Universe Today Podcast

An interstellar meteorite could be hiding in the ocean. Why doesn’t Jupiter have rings like Saturn. The time when Earth’s magnetic field almost collapsed. The shortest day on Earth, and Planet 9 is running out of places to hide.

How JWST is doing after its micrometeorite strike, two more helicopters are flying to Mars, and how do you stop the Milky Way from turning into self-replicating robot probes?

SLS finally gets a launch date for Artemis I, JWST keeps giving the goodness, Percy finds another weird thing on Mars, astronomers find a dormant black hole and NASA will launch a flagship telescope on a SpaceX Falcon Heavy.

Even more pictures from James Webb Space Telescope, China's planning a mission to Neptune, SpaceX's Booster 7 suffers from an explosion, black holes are messy eaters, going under Europa's ice crust and more.

NASA finally released James Webb's first full-color images. We have 5 great photos of different regions of space. So, in this video we're digesting all the great pictures we got from JWST.

In this week's questions and answers show, I explain how Starship will enable enormous space telescopes, if James Webb can look at Hubble, and if future astronomers will have any way of learning about the expansion of the Universe and the Big Bang.

NASA teases JWST images, Rocket Lab launches CAPSTONE, mystery rocket's crash site found on the Moon, how magnetars are created, ISS gets more independent from Russia and more.

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?

SLS finally got through WDR (almost), Falcon 9 are setting new reuse records, China is about to beat NASA to Mars with a sample return mission, Charon red spot explained and more.

Dr. Martin Barstow is is a Professor of Astrophysics and Space Science at the Department of Physics and Astronomy at the University of Leicester and the former President of the Royal Astronomical Society. Dr. Barstow was part of the team who worked on the recent Gaia Data Release 3, which categorized almost 2 billion stars in the Milky Way.

In this week's questions and answers show, I explain why most quasars are very far away, consider what would happen if you brought Pluto into the inner Solar System, and deliver the heartbreaking news of why the ISS won't be recycled.

Dr. Sonny White is a physicist and mechanical engineer. He previously worked at NASA's Eagleworks Lab testing advanced propulsion systems, and developing ideas for faster-than-light travel. He's now working with Limitless Space, founded with the vision of advancing human space exploration beyond the Solar System by the end of the 21st century.

FAA finally gave its approval to SpaceX for Starship launches from Boca Chica, Gaia released its third data drop, China stars continuous space presence, Perseverance finds another weird rock on Mars.

Annika Rollock is a Ph.D. student at the University of Colorado, Boulder. She is studying next generation space habitats and recently published a paper about how future space stations can remain self-sufficient, especially when support and communication from Earth are far away.

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.

Dr. Paul Hickson is a professor of astronomy and astrophysics at the University of British Columbia. Dr. Hickson is overseeing a team that built a telescope out of liquid mercury in India. The International Liquid Mirror Telescope is 4 meters across and built on top of a 3,000-meter mountain in India. This will prove the technology and allow for larger and larger liquid mirror telescopes on Earth (and eventually in space).
