Universe Today Podcast

What's the most challenging part of Astronomy? What happened to Uranus? Which telescope to get for $200? Could we detect Voyager-like spacecraft flying through the solar system? Answering all these questions and more in this week's Q&A.

Interstellar travel might not be as impossible as most people think. Especially if we adopt the multi-stage approach that we already use in everyday rockets. How can we do it and what results we can expect? Finding out in this interview. Guest: Jeff Greason

It’s time for the Perseids meteor shower, Gaia has found hundreds of asteroid moons, Starliner is still in question, and where does the Moon’s atmosphere come from?

Future telescopes like Vera Rubin and Nancy Grace Roman will generate a lot of data. This will be a big challenge. To get ready for it astronomers use simulated observation data. Why is it important and how is it done? Finding out in this interview.

What happens to the stuff that falls into black holes? Do supergiants have sunspots? How can you do a gravitational slingshot from the Sun? Answering all these questions and more in this week's Overtime Q&A.

TRAPPIST-1 is one of the most interesting systems out there. JWST did observe them but we still don't have the results from all of them. Why is that and when can we expect to know something about their atmospheres? Finding out in this interview.

We’ve learned much more from the DART mission, dark oxygen is being generated at the bottom of the ocean, Starliner is almost ready to come home, and we might not need to dig deep to find life on Europa.

John Michael Godier and Universe Today's Fraser Cain discuss the exciting developments in space exploration, focusing on Spacex and the upcoming fifth test launch of Starship. Join us as we discuss the details, analyzing the performance, challenges, and future implications of SpaceX's ambitious project.

What happened at the earliest stages of the Universe and what is it expanding into? Can they just put a telescope inside a Starship? Why do I like the NIAC program so much? Answering all these questions and much more in this week's episode of Overtime Q&A.

Fluids behave very differently in space. We can make good use of it. For example, a recent NIAC grant was awarded to investigate a Magnetohydrodynamic Drive for Hydrogen and Oxygen Production in Mars Transfer. This is a system that should provide breathing oxygen for a journey to Mars made out of water with no moving parts in it. 🟣 Guest: Dr Alvaro Romero-Calvohttps://ae.gatech.edu/directory/person/alvaro-romero-calvo👉 More about the NIAC project:https://www.nasa.gov/general/magnetohydrodynamic-drive-for-hydrogen-and-oxygen-production/🦄 Support us on Patreon: https://patreon.com/universetoday📚 Suggest books in the book club:https://www.goodreads.com/group/show/1198440-universe-today-book-club00:00 Intro01:39 Water in space09:18 The NIAC project28:31 Nightmares in space35:56 Propulsion 44:19 Current obsessions51:53 Final thoughts📺 VIDEO VERSIONhttps://youtu.be/fnKwzi7nvOU📰 EMAIL NEWSLETTERRead by 60,000 people every Friday.
