  • Episode 678: Q&A 126: When Did Mars' Dynamo Shut Off? And More...

    July 30th, 2020  |  20 mins 57 secs
    astronomy, space, space exploration

    In this week's questions show, I consider what the benefits might be to humanity if we discover that we aren't alone in the Universe. How long did Mars planetary dynamo take to turn off? Could we find and repair the lunar rovers?

  • Episode 677: Q&A 125 Can Stars Orbit So Close They're Touching? And More...

    July 24th, 2020  |  33 mins 13 secs
    astronomy, space, space exploration

    In this week's questions show, I explain how it's possible for stars to orbit so closely they're actually touching. What are the limits to gravitational slingshots, and how astronomers know where to point their telescopes in the Universe.

  • Episode 676: Lunar Rovers. From Apollo to Artemis

    July 21st, 2020  |  10 mins 16 secs
    astronomy, space, space exploration

    When the Apollo astronauts first landed on the Moon, they couldn’t go far on foot. That’s 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.

    Now that NASA is returning to the Moon by 2024 as part of its Artemis Program, it’s considering a fleet of new vehicles that will help astronauts roam far and wide across the surface of the Moon.

  • Episode 675: Q&A 124: Are We Even Mentally Capable of Understanding the Universe? And More...

    July 20th, 2020  |  26 mins 17 secs
    astronomy, space, space exploration

    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?

  • Episode 674: A Massive Star Just Disappeared. No Supernova, Just Straight to Black Hole

    July 14th, 2020  |  9 mins 4 secs
    astronomy, space, space exploration

    When the largest stars die, it’s 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 just… vanished?

    Of course, it could have been dust. It’s always dust. But one intriguing possibility is that the star just imploded directly into a black hole, without the supernova detonation. And if that’s the case, is this happening more often, we just didn’t notice it?

  • Episode 673: A New Way to Measure The Expansion of the Universe. The Cosmological Crisis Deepens.

    July 8th, 2020  |  22 mins 19 secs
    astronomy, space, space exploration

    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.

    You'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.

  • Episode 670: NASA is Considering the Trident Mission. Going Back to Neptune and Triton.

    July 3rd, 2020  |  9 mins 29 secs
    astronomy, space, space exploration

    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.

    One of these missions is called Trident, and it’s going to be targeting the Planet Neptune. And more specifically, it’s going to be providing close up pictures of its largest moon Triton.

  • Episode 672: Open Space 85: Final Open Space Before Hiatus, Live QA with Fraser

    July 3rd, 2020  |  1 hr 1 min
    astronomy, space, space exploration

    This week, it'll be the last Open Space with Fraser before the show goes on its summer hiatus until September. If you've got some burning space questions, no will be your chance to ask them.

  • Episode 671: Q&A 123: What if a Supernova Exploded Beside a Black Hole? And More...

    July 3rd, 2020  |  28 mins 33 secs
    astronomy, space, space exploration

    In this week's questions show, I answer what would happen if a supernova exploded right beside a black hole, how do we know that it's impossible to travel faster than the speed of light, can we hitch a ride on an interstellar object, and more...

  • Episode 669: Interview with Fraser on Space Junk Podcast - Mars is the Worst Place to Live

    June 29th, 2020  |  1 hr 1 min

    This is a recent interview with me on the Space Junk, hosted by Tony Darnell and Dustin Gibson about the future of Solar System settlement. Although I'm a huge fan of space exploration in general, I'm not a huge fan of living on other words.

  • Episode 668: Q&A 122: How Will We Know It's Alien Life? And More...

    June 29th, 2020  |  24 mins 9 secs
    astronomy, space, space exploration

    In this week's episode, I answer questions about alien life, why the ISS is at its current altitude, and of course, many questions about black holes.

  • Episode 666: Two Confirmed Planets at Proxima Centauri. One in the Habitable Zone!

    June 23rd, 2020  |  9 mins 17 secs
    astronomy, space, space exploration

    Astronomers have discovered thousands of exoplanets, and still need to confirm thousands more. And over the coming decades, we’ll probably learn of millions of planets, orbiting stars we’ve never heard of.

    That’s why it’s 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.

  • Episode 667: Open Space 84: Are Red Dwarf Planets Doomed? Should the Space Shuttle Have Been Built? And More

    June 23rd, 2020  |  1 hr 51 secs
    astronomy, space, space exploration

    Another week, another Open Space. In this week's questions show, I talk about planets orbiting red dwarf stars, if planets could steal moons from each other, and whether or not the space shuttle should have ever been built.

  • Episode 663: Interview with Fraser on the Interplanetary Podcast

    June 22nd, 2020  |  1 hr 25 mins
    astronomy, space, space exploration

    As you know, I sometimes throw interviews with me on the feed. And this is one I did about a week ago on the Interplanetary Podcast. We talk about a range of things in space and astronomy, and my portion shows up around the 30-minute mark.

  • Episode 664: Open Space 82: What Will Happen in the Next 5 Decades? And More...

    June 22nd, 2020  |  59 mins 11 secs
    astronomy, space, space exploration

    Another week, another Open Space. This week I answer questions about what we might see in the next 5 decades. When dark matter will get debunked, and who will carry the Mars torch after Elon Musk passes away.

  • Episode 665: Open Space 83: Dr. Jamie Molaro on Asteroid Bennu and OSIRIS-REx

    June 22nd, 2020  |  1 hr 1 min
    astronomy, space, space exploration

    In this week's episode of Open Space, I talk with Dr. Jamie Molaro, a planetary scientist who helped discover that the surface of asteroid Bennu has rocks that crack because of the constant day/night cycle.
