JWST has shown us what the modern infrared telescope is capable of. But it's not far-infrared. There are no space telescopes operating in that spectrum at the moment. But why? And what would we be able to see if we had one? Let's find out with Dr David Leisawitz, Chief at NASA Science Proposal Support Office.

This is an episode of John Michael Godier's show Event Horizon. We explore the extraordinary idea of robo-eels, groundbreaking aquatic automatons designed to unlock the mysteries of water worlds like Enceladus and Europa. Then, we shift gears to discuss NASA's riveting UAP study, exploring unidentified aerial phenomena and their implications for our understanding of the universe. Finally, John and Fraser get into the ever changing realm of Artificial General Intelligence (AGI) and contemplate its potential impact on our future.

When we fly to Moon and Mars, how hard will it be to deal with dust. It can be a much more difficult problem when most of us think. And why is it so hard to clean it off solar panels on Mars. We discuss all that with Dr Christine Hartzell.

Magnetospheres seem to be a very important factor when considering how habitable a planet is. So it was really exciting when it was announced that an Earth-size exoplanet's magnetosphere was detected using radio telescopes. It can also be a method to look for exoplanets by detecting their magnetic fields.
\n\nI'm discussing this discovery with Dr Joe Pesce who is the Program Director at National Science Foundation.

Itβs been 50 years since humans set foot on the Moon. Entire generations were born after this historic accomplishment. But humanity has kept its eyes on the sky and vowed to return. This week marks the end of the beginning of that journey, the completion of Artemis I, sending a human-rated capsule around the Moon and back again. With Orion safely back on Earth, letβs look back at this amazing accomplishment and ponder what comes next.

In this week's Questions and Answers show, I explain how astronauts are trained to deal with medical emergencies if the Universe is expanding smoothly or chaotically, and what would survive longer, a white dwarf or a red dwarf?
\n\n00:00 Start
\n01:34 [Tatooine] What if there's a medical emergency on the ISS?
\n04:13 [Coruscant] Could we see before the Big Bang?
\n09:28 [Hoth] Are there stars below the Earth too?
\n12:22 [Naboo] Is there a way to see something moving faster than light?
\n15:00 [Kamino] Why is the SLS fuel tank orange?
\n16:30 [Bespin] Could Titan serve as a fuel depot?
\n18:19 [Mustafar] Would the expansion of the Universe eventually spaghettify all matter?
\n21:37 [Alderaan] If you rode a space elevator, wouldn't you fall back down?
\n23:36 [Dagobah] What lasts longer, a red dwarf or a white dwarf?
\n25:44 [Yavin] Would I like a solution to dark matter or dark energy?
\n26:41 [Mandalore] Why doesn't the Moon fall down to the Earth?
\n28:28 [Geonosis] Has anyone actually tried going the speed of light?
\n29:20 [Corellia] How could we broadcast our existence to aliens?
\n31:47 [Crait] How will astronomers know where to point JWST to see the first galaxies?
\n32:59 [Endor] Could we be inside a nebula?
\n34:44 [Exegol] What new telescope am I looking forward to?

In this week's questions and answers show, I explain how JWST and other telescopes see color, how images from observatories are released to the public, and how much of the sky can JWST see. Also, a bunch of non-Webb questions too.
\n\n00:00 Start
\n01:55 [Tatooine] How does JWST see color?
\n09:58 [Coruscant] How are astronomical images released to the public?
\n12:52 [Hoth] How does JWST handle spacedust?
\n14:48 [Naboo] How is JWST pointed?
\n16:39 [Kamino] Could dark matter be detected in specific parts of the Universe?
\n18:52 [Bespin] Is dark matter just a smart guess?
\n23:10 [Mustafar] Why does Earth have water and the Moon doesn't?
\n26:09 [Alderaan] Is Panspermia inevitable?
\n28:28 [Dagobah] Is the Big Bang a past event or is it still happening?
\n29:43 [Yavin] What's the best telescope to see planets?
\n31:19 [Mandalore] If we mapped the CMB from Andromeda, would it look different?
\n33:10 [Geonosis] Why do we see light from long ago, shouldn't it have passed us?
\n34:49 [Corellia] How can we promote diversity in STEM?
Want to be part of the questions show? Ask a short question on any video on my channel. I gather a bunch up each week and answer them here.

Dr. Malhotra and her team have discovered that Pluto's orbit is surprisingly chaotic at small timescales and yet surprisingly stable at larger timescale. We'll talk about her research and the science of orbital mechanics that led to the current orbits of the planets in the Solar System.","date_published":"2022-04-27T09:00:00.000-07:00","attachments":[{"url":"https://aphid.fireside.fm/d/1437767933/94f97fb6-b72c-4d98-a80a-1e141b67e50c/8dfddc6e-8b55-4eaa-95b5-685efcad652d.mp3","mime_type":"audio/mpeg","size_in_bytes":53759582,"duration_in_seconds":3359}]},{"id":"9173f9a5-bd89-4a8a-8944-0fcb080dfcbb","title":"811: Mission to Uranus, More SLS Problems, Ban for Anti-Satellite Tests | Space Bites e2","url":"https://universetoday.fireside.fm/811","content_text":"Planetary Science Decadal Survey recommends a mission to Uranus, SLS is set for another delay, Perseverance sees a Phobos solar eclipse, all Hubble's images in a single picture and other most important space and astronomy news of the week. \n\n00:00 Intro\n00:43 Planetary Science Decadal Survey is out\nhttps://www.universetoday.com/155519/planetary-decadal-survey-says-its-time-for-a-mission-to-uranus-and-enceladus-too-1/\n04:11 NASA is Having a Tough Time Testing the SLS\n https://www.universetoday.com/155485/nasa-is-having-a-tough-time-testing-the-sls/\n05:46 US goes for a ban of anti-satellite weapons\nhttps://spacenews.com/dod-a-main-proponent-of-anti-satellite-test-ban-we-are-not-disarming/\n07:13 Wow!

\n\n00:00 Start
\n01:22 Could we launch a copy of Hubble?
\n03:34 Could satellites relay information like a mesh network?
\n06:17 Could plants survive on Mars?
\n08:52 Could Planet 9 be dark matter?
\n11:12 Do globular clusters ever collapse into disks?
\n12:36 Are there any new questions about Lagrange Points?
\n14:07 Would the Solar System change if you build a Dyson Sphere?
\n17:08 Could we see the Oort Cloud?
\n19:39 Could we genetically modify humans to survive on Mars?
\n22:32 Are we the center of the Big Bang?
\n24:32 Could a warp drive escape a black hole?
\n25:58 Could we fix Mars by crashing Phobos into it?
\n27:11 Will there be a servicing mission for James Webb?
\n28:41 Will humans visit anywhere other than Mars?
\n31:13 Could life have formed shortly after the Big Bang?
\n32:50 Could a moon be bigger than its planet?
\n34:43 How could the Universe be infinite if it's expanding for a finite time?

\n\n00:00 Start
\n02:11 How would Starship chipsats communicate with Earth?
\n05:00 How far can we ever explore into the Universe?
\n06:31 Why was the SLS test so short?
\n08:59 This is why we test.
\n09:52 What message would we send to aliens we could never visit?
\n13:52 Is anyone working on a practical artificial gravity?
\n18:32 Do we know which stars can see Earth transiting?
\n21:11 How do spacecraft change their trajectories?
\n23:50 When will LUVOIR launch?
\n26:24 Why is there a solar cycle?
\n29:51 Will AI start answering science questions?
\n32:53 Is a generation ship or seed ship better?
\n35:25 Are gravitational lenses like telescope lenses?
\n36:46 Will we hit light speed or wormholes first?
\n37:49 How prepared are we for a Carrington Event?
\n40:48 Can we predict gamma ray bursts?
\n45:52 What are my news sources?
\n48:41 Do I think there's non-intelligent life out there?
\n52:56 Would a Europa lander see any life in the surface?

Black holes are already mind-bending enough. Matter and energy compressed into a region so dense that the escape velocity exceeds the speed of light. Places where space and time are tangled up so much that even if you could go faster than light speed, youβd still end up at the singularity.
\n\nAstronomers know of two kinds of black holes in the Universe: stellar mass and supermassive, and how we get them have been worked out pretty well.
\n\nBut thereβs a third class of black hole, one which has never been observed nor detected indirectly, and yet it could explain some of the mysteries of the Universe, including the nature of dark matter.
\n\nPrimordial black holes.

Well, did you hear the big news? Life on Venus. Lifeβ¦ on... Venus. Now, where have we heard this before? Oh right, life on Mars. If youβve been watching any of my videos or listening to Astronomy Cast, youβre cautiously optimistic. Skeptical, but hopeful.
\n\nThatβs the right position to take, because buckle up, the internetβs about to run with this news. Itβs going to be difficult to figure out what was really discovered, and what this means for the search for life in the Universe.

When the Apollo astronauts first landed on the Moon, they couldnβt go far on foot. Thatβs why the three final missions were equipped with Lunar Roving Vehicles, or Moon buggies, which allowed the astronauts to cover much more ground and do more science.
\n\nNow that NASA is returning to the Moon by 2024 as part of its Artemis Program, itβs considering a fleet of new vehicles that will help astronauts roam far and wide across the surface of the Moon.

In this week's questions show I explain why it's still important to do science, even if it's difficult, can we use multiple methods to measure distance, and why the Trojan asteroids don't collect into a single object?
\n\n00:00 Start
\n00:40 Why should we bother trying to understand the Universe?
\n05:01 Can different methods be used to measure distances to the same object?
\n07:50 Why don't Trojans collect into a single object?
\n10:24 Split the videos up?
\n13:02 Do supernovae cause a chain reaction?
\n14:27 Why settle the Milky Way?
\n16:48 What if a black hole came close to the Earth?
\n18:04 Is there an escape velocity from the Milky Way?
\n18:51 Could we detect something moving faster than light?
\n20:48 Could we detect pulsars in other galaxies?
\n22:44 When does a planet end, and an atmosphere begin?
\n24:06 Could we store photons for energy?

When the largest stars die, itβs usually pretty obvious. Supernovae are visible from billions of light-years away. But recently astronomers watched a massive star just disappear. No explosion, nothing, it justβ¦ vanished?
\n\nOf course, it could have been dust. Itβs always dust. But one intriguing possibility is that the star just imploded directly into a black hole, without the supernova detonation. And if thatβs the case, is this happening more often, we just didnβt notice it?

This episode is a segment that we did in the Weekly Space Hangout talking about how astronomers are using masers (water lasers) to measure the expansion rate of the Universe.
\n\nYou'd think that another, independent way to measure the expansion rate of the Universe would be helpful, but it's only deepened the mystery of the cosmological crisis.

Earlier this year, NASA announced 4 new Discovery-class missions that they were considering. These are low-cost, rapidly-built missions that will help scientists understand some mystery in astronomy and planetary science.
\n\nOne of these missions is called Trident, and itβs going to be targeting the Planet Neptune. And more specifically, itβs going to be providing close up pictures of its largest moon Triton.

Astronomers have discovered thousands of exoplanets, and still need to confirm thousands more. And over the coming decades, weβll probably learn of millions of planets, orbiting stars weβve never heard of.
\n\nThatβs why itβs reassuring to know astronomers are learning a tremendous amount about the closest star system to our own, Proxima Centauri. In fact, we now know of two planets orbiting the red dwarf star, one of which is in the habitable zone.

Iβd say half the astronomy-related videos on YouTube are all about black holes. Clearly, theyβre a fascinating topic, but theyβre also a mystery. How do you observe something that can absorb all the radiation and matter falling onto them, and nothing can ever escape? How do we know theyβre really there, and what are the best observations we can make?
\n\nToday Iβm joined by Dr. Paul Sutter, a cosmologist, and astrophysicist to talk about how we know black holes are really there and not just a figment of an astrophysicistβs imagination?

On Sunday, May 31st, 2020, a SpaceX Crew Dragon capsule carrying astronauts Robert Behnken and Douglas Hurley docked with the International Space Station. This was a tremendous accomplishment for SpaceX and NASA, giving the United States the capability of launching its own astronauts, and no longer relying on its Russian partners.
\n\nThis was the 5th time that US astronauts went into orbit on a new kind of space vehicle, following in the footsteps of Mercury, Gemini, Apollo, and the Space Shuttle.

When youβre out in space, water is the most precious resource you can get your hands on. It can be used for air, water, to grow food, radiation shielding, and most importantly, as the propellant for your spacecraft.
\n\nExploration of the Moon has revealed that thereβs a tremendous amount of water ice locked into the regolith, but itβs probably very difficult to access. But there are also permanently shadowed craters at the Moonβs poles that could have more than enough water to support a permanently inhabitable station on the Moon.
\n\nBut itβs going to be tricky to get at, considering the fact that temperatures in the shadows plunge to -240 degrees Celsius, just 30 degrees above absolute zero.

The distances to other stars are depressingly enormous. Sure, itβs incredibly far to get to Mars, Jupiter, and even Pluto, but at least you can design a robotic spacecraft to make the journey and see the science results in your own lifetime.
\n\nBut in the case of other stars, interstellar flight times will take thousands and even tens of thousands of years to send just a robotic mission.
\n\nFortunately, the Milky Way has got our back. Other star systems have been hurling comets and asteroids towards the Solar System. All weβve got to doβ¦ is catch them.

The Moon orbits around the Earth. The Earth orbits around the Sun. And out in the distant Universe, astronomers have found a system that takes this logical progression to its most extreme. Thereβs a system where a supermassive black hole with millions of times the mass of the Sun orbits another black hole with billions of times the mass of the Sun.
\n\nHow astronomers discovered this incredible interaction took careful observations, imagination, and the hard work of the Spitzer Space Telescope, taken during its final years of operation.

One of the longstanding questions astronomers have had is, are we normal? Is our Solar System a template for what we might expect to see as we look out into the Milky Way at other star systems?
\n\nAs the data continues to come in, the answer to that question really seems to be no, weβre not normal. Star systems seem to have a huge variety of planets orbiting them. Familiar planets like our own terrestrial, gas and ice worlds. But then there are also super earths, mini-neptunes, hot jupiters.
\n\nAnd it looks like there are planets, located in their starβs habitable zone, which are completely covered with liquid water. Like, oceans which are dozens and maybe even hundreds of kilometers deep.
\n\nWhat would it be like on one of these worlds, and of course, we always want to know, could they be habitable?

Mars has been the destination for so many of our spacecraft, and for good reason, itβs probably the most Earthlike place in the Solar System, with water ice on its surface and reservoirs of the liquid beneath the surface. If weβre going to find life, Mars might be the place.
\n\nBut the tiny moons orbiting Mars, Phobos and Deimos, are scientifically fascinating on their own, and so far, a mission has never reached them.
\n\nLast week, Japan announced that theyβve greenlit their Martian Moon eXploration mission, or MMX, which will launch an orbiter, lander and maybe even a rover to Phobos in 2024, returning samples back to Earth by the end of the decade.

After almost 50 years since the Apollo Moon landing missions ended, NASA announced that theyβre going to return to the surface of the Moon with their Artemis mission, ideally taking the first lunar footsteps in 2024.
\n\nNASA Administrator Jim Bridenstine asked for additional funding to achieve this goal, and the other branches of government havenβt been as enthusiastic about this plan. So donβt be surprised if the landing date slips to 2028 or even farther.
\n\nBut NASA is moving forward on its architecture to return humans to the Moon, from its launch rocket to the entire method of getting astronauts down to the surface.
\n\nExactly which rockets, modules and landing systems that will be used are still getting worked out, with different options still getting considered.

In this week's questions show, I talk about how we're in a new space race, and what this means for returning to the Moon. Of course, lots of follow up answers about the Fermi Paradox. Could Betelgeuse release gravitational waves if it explodes? And what is our responsibility if we are truly alone in the Universe?

Itβs hard to really wrap your mind around the vast distances between stars. The fastest spacecraft ever launched into an interstellar trajectory right now is Voyager 1. If it was directed at the nearest star, it would take tens of thousands of years to make the journey across the interstellar gulf.
\n\nEven so, groups like Breakthrough Starshot and Icarus Interstellar are working on plans right now to try and send spacecraft to other stars, ideally within our lifetimes.
\n\nBut we can see how quickly technology is advancing all around us, from materials science to high energy physics, not to mention reusable rockets.
\n\nIt seems reasonable to ask, should we invest in an interstellar mission now, or wait a few decades or even centuries for better technology to come along which could make the trip much shorter?

Near the end of 2019, astronomers watching the red giant Betelgeuse noted how much the star had dimmed, continuing to steadily fade for months.
\n\nItβs a variable star, and itβs known to get dimmer and brighter, but the big surprise is that itβs still continuing to dim, recently passing magnitude 1.56 and still getting dimmer. This is unprecedented in the decades that astronomers have been watching the star.
\n\nThe worldβs biggest telescopes are on the case, and the European Southern Observatory released dramatic new images of Betelguese, resolving features on the starβs surface and surrounding area showing how itβs dramatically changed over the course of 2019.

00:40 Are there multiple Great Filters?
\n02:35 Could we refuel ships in space to land on Mars
\n06:01 Could we put a light on the Moon to prove what we landed there?
\n08:18 Will James Webb Launch?

On February 9, 2020, the European Space Agencyβs Solar Orbiter spacecraft launched from Cape Canaveral Florida on top of an Atlas V 411 spacecraft. The spacecraftβs mission is to fly inside the orbit of Mercury, on a tilted orbit that takes it above and below the Sun, capturing images of the Sunβs poles for the first time.
\n\nThis is just a year and a half after the launch of NASAβs Parker Solar Probe, which will fly even closer. Together, the two spacecraft will measure the Sun from every angle up close, providing detailed images and insights of our closest star, to help understand how it creates and controls the giant bubble of plasma that surrounds the entire Solar System.

Youβre looking at the highest resolution image that has ever been taken of our Sun, using the brand new Daniel K Inouye Solar Telescope in Maui.
\n\nThese lighter regions are convection cells, blobs of hot gas the size of Texas which have carried heat from deep below the surface of the Sun, releasing it into space. The darker lines are cooler regions, where the material is sinking back down into Sun.
\n\nThis image is just a demonstration of the incredible power of this 4-meter observatory, which will join NASAβs Parker Solar Probe and ESAβs Solar Orbiter in ushering in the golden age of solar astronomy.

On Sunday, January 19th, 2020, SpaceX launched a Falcon 9 rocket carrying its newly designed Crew Dragon spacecraft. 84 seconds into flight, at the moment of maximum aerodynamic pressure, the capsule fired its eight SuperDraco thrusters, detaching from the top of the rocket and flying ahead.
\n\nMoments after, the Falcon 9 rocket exploded in midair, destroying a completely good rocket, but the capsule was completely safe, jettisoning its trunk and landing gently in the ocean a few minutes later.
\n\nNobody was on board the spacecraft, just a couple of test dummies, but this test proved that in the case of an emergency during the ascent stage fo the mission, Crew Dragon would be able to carry its astronaut crew to safety.

In 2006, astronomers spotted the telltale sign of a supernova detonating in the galaxy NGC 1260, located about 240 million light-years away in the constellation of Perseus. As telescopes around the world turned their collective light-gathering power on the expanding explosion designated as SN 2006gy, they realized they were seeing something very unusual.
\n\nThis clearly wasnβt a regular supernova. It grew to be 100 times brighter than the typical stellar explosion and lasted much much longer.
\n\nMore than a decade after that cosmic explosion, astronomers finally think they know what series of events led to the release of this much energy, now called a superluminous supernova. A red giant ate a white dwarf. An event so rare it probably accounts for only 1 in 1000 supernovae.

Whenever I talk about the search for life in the Universe and its emphasis on water, I get comments that scientists arenβt being creative enough. Why does life rely on water? Couldnβt there be lifeforms which are completely different from life on Earth? Isnβt that the textbook definition of alien?
\n\nAstrobiologists have only scratched the surface in their search for life in the Universe, and theyβre going after the low-hanging fruit. Since life on Earth can be found wherever thereβs water, why not check out the water on other worlds? If that doesnβt pan out, then theyβll expand the search.
\n\nBut itβs possible there are aliens living right here on Earth among us, in a shadow biosphere, we just havenβt detected them yet.

In 2015, scientists discovered the telltale signal from ripples of spacetime sweeping over the Earth. It was the very first direct detection of gravitational waves, generated by the merger of two massive black holes 1.3 billion light-years away.
\n\nThis discovery was the culmination of decades of research and construction of huge instruments called interferometers to detect the warping of spacetime caused by gravitational waves.
\n\nToday, the most advanced detectors, the LIGO/VIRGO collaboration, have turned up over 50 gravitational wave discoveries - on average one every week - allowing astronomers to perceive the Universe in a completely different way.
\n\nWhat new gravitational wave instruments are in the works, and what does the future hold for this relatively new field of study?

In this week's questions show, I explain why it doesn't make sense to send a microscope to Mars, how we could use a black hole to see a reflection of Earth and see dinosaurs, and why we don't just send a solar sail down to the Sun.
\n\nFeaturing Stella Kafka from the American Association of Variable Star Observers
\nhttps://www.aavso.org/
00:42 Why no microscopes to Mars?
\n02:38 Could we see a reflection of Earth?
\n04:37 Send a solar sail to the Sun?
\n07:03 How will red dwarfs die?
\n08:51 Do radio telescopes have pixels?
\n10:58 Do aliens have to be close to detect us?
\n13:21 Will civilizations want to settle every star?
\n15:17 What is expanding in between space?
\n17:18 Will we get out of balance with nature?
\n21:42 Do black holes come in different shapes?
\n24:03 How could a civilization go extinct?
\n26:37 Are their models for dying stars?

Weβve now passed the 50th anniversary of the Apollo 11 landing, and all eyes are back on the Moon. NASA is planning to return to the Moon by 2024 with its Artemis mission, the Chinese have put the Moon firmly in their plans for space exploration, and even SpaceX thinks the Moon is the perfect destination to test out the capabilities of its Starship.
\n\nBut what can you do with the Moon? Refuel spacecraft with resources drawn from the lunar regolith? Mine its helium 3 for your fusion reactors? Build a lunar amusement park?
\n\nIn fact, the far side of the Moon might make one of the best platforms we have for radio telescopes. One side of the Moon is completely blocked from Earthβs constantly increasing radio traffic, giving it the perfect view to the most sensitive radio signals in the Universe.

On Monday, January 6th, 2020, another SpaceX Falcon 9 blasted off from Cape Canaveral, carrying another 60 Starlink internet communications satellites, bringing the full size of the constellation to 180. With just three launches, SpaceX becomes the largest satellite operator in the world.
\n\nBut the company is just getting started. Theyβre planning to do this again every couple of weeks during 2020, bringing the total number of satellites in the constellation to about 1440, which is enough to provide high-speed internet services to the United States and parts of Canada.
\n\nShortly after launch, as the satellites are raising their altitude, theyβre clearly visible to the eye as they streak across the sky in a close train.
\n\nAstronomers arenβt happy.

Once again, at the AAS Meeting in Hawaii, I got a chance to sit down with another astronomer to talk about their research. This time it was Dr. David Kipping from Columbia University's Cool World's Lab. We talked about how easy it'll be for aliens to know our planet is inhabited, and some ways we might be able to hide the evidence of our existence.

At the American Astronomical Society's meeting Honolulu I got a chance to talk with Adam Frank about new research he's worked with Caleb Scharf, Jonathan Carroll-Nellenback and Jason Wright about the Fermi Paradox. They calculated how difficult it would be for aliens traveling at 10% the speed of light to settle the entire Milky Way, and it turns out, it's not as simple as you might think.

Over the last weekend, astronomy Twitter started noting that the red giant Betelgeuse, the prominent shoulder of Orion was looking visibly dimmer in the sky, and I had a few people reach out to me and ask me if it was really happening and if I knew what was going on.
\n\nThis is exciting, of course, because Betelgeuse is living on borrowed time, and it could explode as a supernova any day now. Or, it might not detonate for another 100,000 years. We just donβt know.

As Iβm recording this video near the end of 2019, the total number of confirmed exoplanets stands at 4,104. Weβve come a long way since the discovery of the first exoplanet orbiting a sunlike star back in 1995 with 51 Pegasi b.
\n\nAnd the reality is that the race to find new exoplanets is only accelerating. New ground and space-based telescopes are turning up planetary candidates at an increasing rate. New techniques will find planets in entirely new ways. The bottom line is that over the next few decades, this mere 4000ish will multiply by orders of magnitude.
\n\nSo letβs run the clock forward and try to calculate what the future holds for exoplanets. How many worlds will we know about 3 decades from now, in the year 2050?

How old is the Universe? In order to figure that out, all you have to do is figure out how quickly itβs expanding, and then the clock backward until everything is crunched together.
\n\nAnd astronomers have measured the rate that the Universe is expanding with tremendous precision at various times in its history; at the beginning, and much more recently. The problem is, these expansion rates disagree, but theyβve both been measured so accurately that their error bars donβt overlap.
\n\nIn other words, there are multiple, highly accurate estimates for the age of the Universe, and they disagree.

In this week's questions show, I explain why I don't think we always need to be realistic, if galaxies in the local group are bound together gravitationally, and what we should call Earth-moving equipment on Mars.
\n\n00:20 Be realistic.
\n04:24 Are galaxies in the local group bound?
\n05:56 Will gravitational waves give us advanced notice of collisions?
\n08:36 Will we ever be able to live outside on Mars?
\n10:16 Are we going to ruin Mars too?
\n12:42 Mars-moving equipment?
\n14:07 Could the Moon have an atmosphere?
\n15:51 Liquid water on the surface of Mars
\n16:49 Is there a business case for Mars?
\n19:17 What about nitrogen?
\n21:21 What will need to come from Earth?
\n23:06 Are there planets with less gravity than Earth?

Extending humanity to other worlds in the Solar System is at the very limits of our modern technology. And unless there are dramatic discoveries in new propulsion systems or we learn how to build everything out of carbon nanotubes, the future of space exploration is going to require living off the land.
\n\nThe technique is known as In-Situ Resource Utilization or ISRU, and it means supplying as much of your mission from local resources as possible.
\n\nAnd many of our future exploration destinations, like Mars, have a lot to work with. Letβs look at the raw materials on Mars that missions can use to live off the land and the techniques and technologies that will need to be developed to make this possible.

The exploration of Venus has been mainly about getting down to the surface of the planet. The Soviet Union sacrificed lander after lander to discover just how extreme the conditions are down there on the ground.
\n\nBut higher up, among the clouds, the climate on Venus is surprisingly Earthlike in temperature and pressure, and there have been some fascinating ideas for robotic and human explorers to fly the skies of Venus, to help understand our evil twin planet.
\n\nLetβs take a look at them.

In this week's questions show, I explain why we can see meteor showers every year, why we're not 3D printing telescopes in space, why there aren't any plans to launch telescopes with SpaceX Starship. And a lengthy answer to one of the most common James Webb questions we get: can it be refueled? This was answered by Paul Geithner, a Deputy Project Manager for James Webb during a recent livestream.
\n\n01:00 Why do we see meteor showers every year?
\n02:49 Why not also use 3D printing for space telescopes?
\n04:40 Why don't they design telescopes for Starship?
\n07:20 Could there be a privately backed telescope?
\n09:54 Is there glass on the Moon to build telescopes?
\n11:46 Could ISS help build new space telescopes?
\n13:47 Space telescopes on the far side of the Moon?
\n15:06 Is Andromeda actually much closer?
\n16:27 Why spend money on science?
\n19:20 Why is the dark side of the Moon illuminated?
\n21:34 Can James Webb be refueled?

\n\nhttps://caseyhandmer.wordpress.com/
\n\nWe talked about the implications of SpaceX Starship, Starlink, why power beamed from space or asteroid mining will never turn a profit down here on Earth, and why he's not that scared about space radiation.

When it comes to telescopes, bigger is better. Thatβs true down here on Earth, and itβs especially true out in space. As astronomers and engineers design the next generation of giant space telescopes, theyβre running up against the limits of current launch providers. There are only so many ways you can fold a huge telescope to get it to fit inside a 5-meter launch fairing.
\n\nThe upcoming James Webb Space Telescope is pretty much the very limit of what you can construct on Earth and put into space in a single launch. To go bigger, space agencies will need to consider assembling their next-generation space telescopes⦠in space.

In this week's questions show, I tackle all the questions about James Webb generated by the videos we did this week. Can it be refueled? How can it see the entire sky? Is the delay a blessing? And more...
\n\n00:30 How will JWST run out of propellant?
\n03:12 Are there spacecraft that could service JWST?
\n05:00 Can JWST only see half the sky?
\n08:21 Is the delay a blessing in disguise?
\n10:58 Why not construct it in Low Earth Orbit?
\n13:09 Could we build a copy?
\n14:29 Could JWST use gravitational lensing?
\n15:55 Will JWST image black holes?
\n17:52 Is the telescope an antique?
\n18:49 Should we look or explore?
\n20:52 Could it find vegetation?
\n22:00 Is James Webb already a failure?

On March 30, 2021, NASAβs James Webb Space Telescope will blast off from the European Space Agencyβs European spaceport in Kourou, French Giana on board an Ariane 5 rocket.
\n\nItβll fly to the Sun-Earth L2 Lagrange point, a relatively stable spot in space that keeps the glare from the Sun, Earth, and Moon all in a tiny spot in the sky. Then, itβll unfurl its tennis court-sized sunshade, fold out its gigantic 6.5-meter mirror, and peer out into the distant cosmos.
\n\nOver the course of the next 10 years, this infrared observatory will help astronomers learn about the earliest moments of the Universe, directly observe the atmospheres of planets orbiting other stars, and peer at newly forming stars and planets.
\n\nAnd if you listened to the words I just said with equal parts terror and skepticism, I donβt blame you. James Webbβs path to space has been long and tortuous. And the risks that the mission still faces are very real. Hopefully, the science will be worth it. Hopefully, nothing else goes wrong from now until deployment.
\n\nSo today, I want to do a deep dive into James Webb. To talk about the history of the mission, why it exists, how the development went, and where it stands today.
\n\nIβll warn you though, the length of this video is going to go way over budget.

Solar energy is the ideal way to power a spacecraft. Thereβs no weather, thereβs no pesky atmosphere, just pure photons streaming from the Sun to harvest for whatever you need. Well, as long as youβre within the inner Solar System.
\n\nBut solar panels are complicated and fragile made of sensitive electronics and glass - not to mention, really heavy. Any spacecraft equipped with solar panels needs to handle the gravity down here on Earth for the construction and testing, then the shaking and high Gs of launch. The solar panels need to unfold perfectly once they get to space. And the total amount of energy you can harvest is limited by the size of your rocketβs launch fairing.
\n\nMaybe thereβs a new strategy. NASA is currently funding research into a new type of solar panel that can be carried into space as a liquid and then sprayed onto a surface to turn it into a power generating surface.

The race is on to find life in other places in the Solar System, from underground reservoirs on Mars to the subsurface oceans on Europa and Enceladus.
\n\nIf spacecraft, rovers or even astronauts make the momentous discovery of life on another world, thatβll just open up new questions. Did it originate all on its own, completely independently from Earth, or are we somehow related? And if we are related, how long ago did our evolutionary trees branch away from each other.
\n\nEven though Mars is millions of kilometers away, it could be possible that weβre still related thanks to the concept of Panspermia; the idea that meteor impacts could transfer rocks and maybe even living creatures from world to world.
\n\nBut could you go one step further? If we find life on another star system, could we discover that weβre actually related to them too? Is Galactic Panspermia possible?

If youβve watched this channel enough, you might have the impression that I hate Venus. Itβs possible, just possible Iβve even suggested that the planet is so terrible it should be pushed into the Sun.
\n\nThe reality, of course, is that itβs an absolutely fascinating world - the closest twin to the Earth that we have in the Solar System. Itβs nearly the same mass and has the same surface gravity.
\n\nWhile Earth is the beautiful life-filled world we all enjoy, Venus is a tortured hellscape, with temperatures hot enough to melt zinc. With atmospheric pressures more than 93 times what we experience here on the surface of Earth. And I always forget about the sulphuric acid rain.
\n\nThe Soviets sent a series of landers to a horrible demise for a glimpse of the surface of Venus in the 70s and 80s. But nobodyβs been back since.
\n\nThere have been new techniques and technologies in development that might make a serious exploration of the surface of Venus possible again. Exploration that could help us understand why the planet went so horribly horribly wrong.

In this week's questions show, I explain why it's probably not time to reconsider the definition of a moon, if we could make artificial gravity with a chunk of a neutron star, and why a supermassive black hole isn't the anchor for an entire galaxy.
\n\n00:47 Should we reconsider the definition of a moon?
\n03:35 Could we make artificial gravity with mass?
\n05:48 Why didn't the Big Bang collapse back into black hole?
\n07:47 Why can't a black hole be the anchor of the galaxy?
\n10:45 How far and how small can we see?
\n13:37 What is left after a black hole evaporates?
\n15:00 Could you have a star made out of something else?
\n16:32 Could a planet orbit a binary star?
\n18:29 Could aliens Planet 9?
\n19:24 If aliens are advanced, we're no threat
\n21:35 How can aliens not exist?
\n22:30 Why don't they put a microscope in a rover?

Scientists have had the opportunity to examine several asteroids in the Solar System now, and what theyβve learned is how much variety is out there, depending on the mass, distance from the Sun and composition.
\n\nAstronomers currently know of 829,400 asteroids across the Solar System, and theyβd love to visit as many of them as possible to learn more about them.
\n\nConsidering the price of a single spacecraft, thatβs going to get expensive. Fortunately, there are places in the Solar System that have trapped a large number of asteroids in a way that a single spacecraft can visit several of them as part of a mission.
\n\nTheyβre at Jupiterβs L4 and L5 Lagrange points, and this week NASA approved a new mission thatβll explore 7 different asteroids over a 12-year journey.
\n\nItβs called Lucy.

People always ask me how I think humanity will react if we discover life somewhere out there in the Universe, whether itβs bacteria under the surface of Mars, a biosignature of alien life in the atmosphere of another world, or a radio signal from another civilization.
\n\nWill our civilization lose its collective mind and have a temper tantrum on a global scale? Will we become one of those purge planets from Rick and Morty?
\n\nWill the discovery suddenly end all religion, as we wait for guidance from our new alien overlords?
\n\nWill we gather together as a species to present a common front to whatever cosmic horrors await us beyond the Solar System?
\n\nIn my opinion, if I could sum up the collective response in a single word, it would be: meh.

No guest this week, just a live QA with me and the audience about all things space and astronomy. People had questions about how planets can capture asteroids to turn them into moons, what rocket James Webb will use to fly to space, and why you can't use antimatter to destroy a black hole.
\n\n05:45 How can a planet capture an asteroid?
\n07:21 Why are quasars so far from us?
\n09:26 How could you make a black hole of photons?
\n11:25 Would I rather live a year on the Moon or Mars?
\n12:46 What will JWST launch on
\n14:08 What's the limit on a planet's mass for rocketry?
\n17:06 Do I prefer to observe alone?
\n18:55 Why doesn't antimatter destroy black holes?
\n20:43 Will we get space engines from The Expanse?
\n24:05 Shouldn't we solve our problems here on Earth?
\n26:30 What happens to us when the Sun dies?
\n28:28 Why aren't there video cameras on Mars?
\n30:00 How do we learn about what things are made of with radio waves?
\n32:00 Are there any metals in space that can't find on Earth?
\n33:12 How do we measure distances to stars?
\n35:16 EMDrive
\n36:23 Are metals precious to the planet you're on
\n37:05 Will Skylon fly?
\n38:35 Cyanogen gas in comets
\n39:12 Talking to people who don't care about space
\n41:00 How do planets start forming?
\n41:48 What do I think of antimatter rockets?
\n43:09 Could we build an arm to lift us to space?
\n43:32 Should we just colonize space itself?
\n44:20 Is Planet 9 a black hole?
\n50:11 Does Canada have radio telescopes?
\n50:50 When will a black hole turn into regular matter again?
\n51:30 Wildlife on Vancouver Island
\n53:13 Could breakthrough starshot work to redirect asteroids?
\n54:25 Could we see life on Alpha Centauri?
\n57:00 Is Alpha Centauri visible from the North?

Even as the first rockets were launched into space decades ago, aerospace knew it was a wasteful process. Rocket stages, motors, and complex equipment crashed into the ocean or burned up in the Earthβs atmosphere.
\n\nCould spaceplanes bring the costs down? Flying to orbit with a combination of jet engines and rockets and then safely re-enter the Earthβs atmosphere again.
\n\nSingle-stage to orbit spacecraft and spaceplanes have always seemed out of reach, and actually not that practical. But what about a two-stage, fully reusable spaceplane?
\n\nExodus Space Corporation has been secretly working on this concept for a decade now, and what theyβre proposing is pretty revolutionary.

While weβre all waiting for James Webb to launch - which it will - the Extremely Large Telescope to be constructed, and LUVOIR to get approved.
\n\n(Please get approved, please get approved.)
\n\nWeβre going to need a way to pass the time. So letβs have our imaginations take flight, out into the Universe, and consider some of the most incredible ideas suggested for telescopes.
\n\nUnless youβve been crawling through scientific journals like me, I guarantee youβve never heard of any of them. But when Iβm done, youβre going to want to fund all of them.

In this week's questions show, I explain why Starship probably won't contribute to human carbon emissions, if there's a galactic Prime Directive, and if SpaceX has finally perfected the single-stage to orbit.

After decades of research, including multiple landers and orbiters, science can definitively say: Venus sucks. Seriously, that place is the worst, with its boiling temperature, intense pressure, sulfuric acid rain, and more.
\n\nBut was it always this bad? According to new research from NASA and various universities in Sweden and the US, Venus might have actually been the first habitable world in the Solar System. And it might have maintained a reasonable climate for billions of years, finally rolling over into a runaway greenhouse effect just a few hundred million years ago.

On Saturday, September 28th, SpaceX CEO Elon Musk stood in front of an audience in Boca Chica, Texas, and presented the fully assembled SpaceX Starship, 50 meters tall and made from shiny stainless steel.
\n\nAs part of his presentation, Musk showed off the history of the companyβs developments so far and gave us an updated view of what Starship and its first stage Superheavy booster will look like when theyβre fully operational.
\n\nIt was actually a pretty short presentation, and there werenβt a lot of details. But he stuck around to answer questions from many space journalists, and weβve got a much better idea about Starship and what happens next.

In 2017, Elon Musk laid out his grand sweeping plans for the future of SpaceX, the company that would take humanity to Mars. Over decades, tens of thousands of Starship flights would carry a million human beings to the surface of the Red Planet, the minimum Musk expects itβll take to create a self-sustaining civilization.
\n\nThe number of details in an effort like this is mind-boggling. What about the reduced gravity, radiation exposure, and space madness? What about return flights? Replacement parts? Building materials?
\n\nWhatβs everyone going to eat?

One of my most requested guests is Dr. Robert Zubrin, engineer and founder of the Mars Society. It was Dr. Zubrin's "Case for Mars" that helped inspire me to get into space journalism in the first place. We had a wide-ranging interview that updated the Case for Mars, looked at what comes next, and how current efforts are stumbling in their efforts to return humans to the Moon, and then on to Mars.

This week I was joined in a livestream with Dr. David Kipping from Columbia University. We had a great interview about his research into exomoons, what new observatories will do for this field. We also talked about his idea of the Terrascope, using the Earth's atmosphere as a lens to study the Universe. And we talked about how scientists can better use the internet to communicate directly with the public about their research.

Iβve said many times in the past that the Earth is the best planet in the Universe. No matter where we go, weβll never find a planet thatβs a better home to Earth life than Earth. Of course, thatβs because we, and all other Earth life evolved in this environment. Evolution adapted us to this planet, and itβs unlikely we could ever find another planet this good for us.
\n\nHowever, is it the best planet? Are there places in the Universe which might have the conditions for more diversity of life?

Humans to Mars. Thatβs the plan right? The problem is that sending humans down to the surface of Mars is one of the most complicated and ambitious goals that we can attempt. Itβs a huge step to go from low Earth orbit, then lunar landings, and then all the way to Mars, a journey of hundreds of millions of kilometers and 2 years at the least.
\n\nBut there are two places humans can go which are a stepping stone between Earth and Mars. Base camps that would let us gather our resources in relative safety before dropping down into that gravity well.
\n\nIβm talking about the moons of Mars: Phobos and Deimos.

Weβre learning more and more about extrasolar planets, and for the first time, astronomers have discovered water vapor in the atmosphere of a planet orbiting another star. The planet is located in the habitable zone of its star, so this might even be rain.
\n\nOf course, itβs not all good news, itβs much more massive than Earth, with higher gravity, and is probably bathed in radiation from its red dwarf star. But, itβs a good start in the search for habitable places in the Universe, places where there might be life.

Lagrange Points. Stable spots in space that you just canβt stop thinking about. What spacecraft work best in which places? What are some amazing ideas that could utilize these regions across the Solar System?
\n\nIn the last episode, I gave an overview of the Lagrange points, and then went into the details of spacecraft missions sent to L1, the perfect place to constantly observe the Sun, the Earth, or to block radiation coming from the Sun. The best place for a lunar elevator, or a spot to put a space station at the Moon.
\n\nThis week, weβre going to talk about L2 and L3, the other meta-unstable spots that you can park a spacecraft at.

Thanks to gravity, there are places across the Solar System which are nicely balanced. Theyβre called Lagrange Points and they give us the perfect vantage points for a range of spacecraft missions, from observing the Sun to studying asteroids, and more.
\n\nVarious spacecraft have already visited Lagrange Points, used them for some or all of their missions, and there are fascinating plans in the works that could put new missions and even space colonies into these balanced places in the Solar System.
\n\nLetβs explore the Lagrange Points.

One of the great accomplishments of the Apollo missions was to bring home hundreds of kilograms of lunar rock. Suddenly, geologists had a lifetimeβs worth of lunar samples captured from several different spots across the Moon. These rocks and dust have been under continuous analysis since the Apollo 11 astronauts came home over 50 years ago.
\n\nAnd theyβre still making discoveries.
\n\nScientists have samples of the Sunβs solar wind, particles from a cometβs tail, a few grams from an asteroid, with more coming shortly.
\n\nBut thereβs one world, the focus of so much scientific study, which has never had a sample returned: Mars.
\n\nNASA and the European Space Agency have been making plans to bring a sample home from Mars for decades, and now, missions could fly in the next few years, finally bringing a chunk of the Red Planet home to Earth for us to study directly.

As Iβve mentioned in several episodes now, humanity is in a bit of a transition period, a time when it makes sense to launch material up and out of Earthβs gravity well into orbit, and beyond. But itβs really expensive, costing up to $10,000 per pound you want in orbit, and 10 times if you want it on the Moon.
\n\nBut over the coming decades, more and more of our space-based infrastructure will be built in space, manufactured out of materials that were mined in space.
\n\nThe only thing thatβll actually need to leave the Earthβs clingy gravity well will be us, the humans, the tourists, wanting to visit all that space infrastructure.
\n\nOf course, in order to achieve that space future, engineers and mission planners will need to design and construct the technology that will make this possible.
\n\nThat means testing out new prototypes, technologies and methodologies for mining and space-based manufacturing.

Mars is the place that most of our spacecraft, landers and rovers are studying, searching for any evidence that life ever existed somewhere else in the Solar System.
\n\nBut talk to planetary scientists, and theyβre just as excited about the ocean worlds of the Solar System; the moons, asteroids, dwarf planets and Kuiper Belt objects where there could be vast oceans of liquid water under thick shells of ice.
\n\nThe perfect environment for life to thrive.
\n\nWeβve only had tantalizing hints that these oceans are there, but NASA is building a spacecraft that will study one of these worlds in detail: the Europa Clipper. And theyβre not the only ones. The European Space Agency is building their own mission, the Jupiter Icy Moons Explorer.

On Tuesday, July 30th, NASA announced 19 different partnerships with 13 different companies to use their expertise to help them develop space technologies, from advanced communications systems to new methods of entry, descent and landing.
\n\nInstead of contracting out specific projects, NASA will make its employees, facilities, hardware and software available to these companies, for free.
\n\nOne of the most notable of these partnerships will be with SpaceX and NASAβs Glenn and Marshall Centers to help advance the technology of transferring propellant in orbit.
\n\nIn other words, NASA is going to help SpaceX figure out how to refuel a spacecraft while itβs in space. And if they can figure this out, it could completely change the way missions are launched and flown.

Itβs amazing to think there are telescopes up in space, right now, directing their gaze at distant objects for hours, days and even weeks. Providing a point of view so stable and accurate that we can learn details about galaxies, exoplanets and more.
\n\nAnd then, when the time is up, the spacecraft can shift its gaze in another direction. All without the use of fuel.
\n\nItβs all thanks to the technology of reaction wheels and gyroscopes. Letβs talk about how they work, how theyβre different, and how their failure has ended missions in the past.

NASAβs Transiting Exoplanet Survey Telescope launched back in April, 2018. After a few months of testing, it was ready to begin mapping the southern sky, searching for planets orbiting stars relatively nearby.
\n\nWeβre just over a year into the mission now, and on July 18th, TESS has shifted its attention to the Northern Hemisphere, continuing the hunt for planets in the northern skies.
\n\nAs part of this shift, NASA has announced a handful of fascinating new planets turned up by TESS, including a couple of worlds in categories which have never been seen before.

When we look outward into space, weβre looking backwards in time. Thatβs because light moves, at the speed of light. It takes time for the light to reach us.
\n\nBut it gets even stranger than that. Light can be absorbed, reflected, and re-emitted by gas and dust, giving us a second look.
\n\nTheyβre called light echoes, and allow astronomers another way to understand the Universe around us.

There are few places in the Solar System which are as fascinating as Saturnβs moon Titan. Itβs a world with a thicker atmosphere than Earth. Where itβs so cold that it rains ammonia, forming lakes, rivers and seas. Where water ice forms mountains.
\n\nLike Europa and Encleadus, Titan could have an interior ocean of liquid water too, a place where there might be life.
\n\nTitanβs got layers, and fortunately, thereβs an awesome new mission in the works to explore it: the Titan Dragonfly mission.

As NASA prepares to return to the Moon by 2024 as part of its Artemis program, the agency is focusing its efforts on exploring the Moonβs polar regions. These are areas of the Moon which seem to have a lot of water mixed in with the regolith.
\n\nSome of these craters are permanently in shadow, and might still have large quantities of water, thatβs accessible to human and robotic explorers. This is a critical resource, and the Moon might be just the place to help humanity as it pushes out to explore the rest of the Solar System.
\n\nBut it might also be an illusion. We really wonβt know until we look up close.

Where you can travel in space depends on how much propellant youβve got on board your rocket and how efficiently you can use it. But thereβs a source of free propellant right here in the Solar System - the Sun - which is streaming out photons in all directions. You just need to catch them.
\n\nAnd right now, the Planetary Societyβs new LightSail 2 spacecraft is testing out just how well itβll work.

In this week's QA, I tackle constant acceleration. Do we have anything that can accelerate at 1G for long periods of time? Why are there different sized stars? And do the heavier elements come from supernovae or colliding neutron stars?

On October 19th, 2017 astronomers detected the first interstellar asteroid (or maybe comet) passing through the Solar System: Oumuamua. It had a brief encounter with the inner Solar System and then hurtled back out into interstellar space.
\n\nOnce astronomers noticed it, they directed the worldβs telescopes on the object, but it was too far away to reveal anything more than a faint dot.
\n\nUntil now, weβve only been able to study objects in our own Solar System. We have no idea what the rest of the Milky Way is like.
\n\nBut we were too late to catch it, no spacecraft was ready to make a quick intercept.
\n\nWell, scientists arenβt going to make that mistake again. The European Space Agency announced their plans to build a comet interceptor. A spacecraft that will lurk out at the Earth-Sun L2 Lagrange point, waiting for a long-period comet or interstellar object to pounce on, and give us the first close up view ever.

People are always worried that alien civilizations will detect the transmissions from our old radio shows and television broadcasts, and send in the invasion fleet. But the reality is that life itself has been broadcasting the existence of life on Earth for 500 million years.
\n\nBlame it on the plants.
\n\nIn addition to filling the atmosphere with oxygen, plants give off a very specific wavelength visible in infrared radiation. Itβs the kind of signal that other civilizations could search for as theyβre scanning the galaxy.
\n\nItβs what weβll be looking for too.
\n\nBut donβt just blame the plants. Other forms of life have been giving off signals too, signals we can search for as we discover new exoplanets and wonder if they have life there.

This past weekend Skylias moderated a debated between John Michael Godier and Fraser Cain over their Fermi paradox theories. If there are aliens where are they? The Fermi paradox theory asks where are the alien civilizations in the galaxy? And in the universe. If they exist. Where are the extraterrestrials?

The Solar System is a really big place, and it takes forever to travel from world to world with traditional chemical rockets. But one technique, developed back in the 1960s might provide a way to dramatically shorten our travel times: nuclear rockets.
\n\nOf course, launching a rocket powered by radioactive material has its own risks as well. Should we attempt it?

Explorers have always brought stowaways with them on board. Thanks to our travels around the world, hardy creatures like rats, goats, pigs and starlings and more have found their way to every corner of the globe. Not to mention our plants, microbes and viruses.
\n\nWherever we go, life goes with us, whether we want it to or not. And when we travel to other worlds, it looks like the most extreme life Earth has ever cooked up is ready and willing to make the journey with us.
\n\nNow that the big flybys are over, itβs time to dig into the regolith, search for life in underground lakes and oceans, return samples back to Earth. Weβre going to give life every opportunity to contaminate other worlds.
\n\nWhat can we do to prevent it?
