Universe Today Podcast

White dwarf stars should be cooling down practically till the end of the Universe. But yet, they don't. They stop cooling at some point. Why does this happen? Figuring out the answers with Dr Simon Blouin from the University of Victoria.

How do we plan a mission that can go to Enceladus and grab a sample of its plumes? How fast does it need to go? Will it bring samples to Earth or analyse them on the spacecraft? Figuring out the answers with Professor Mark Burchell from the University of Kent.

Understanding the surface of Betelgeuse, James Webb’s third observing cycle has been announced, Starship’s upcoming third test, and the most massive pair of black holes ever seen.

Why won't NASA send a copy of Perseverance to the Moon? Can life exist on a planet around a blue giant star? How do satellites stay safe in orbit and don't collide with each other? Answering all these questions and more in this week's Q&A show.

Self-replicating space robots seems as an obvious way to explore the Universe. How close are we to such a scenario and what do we need to fill outer space with Von Neumann probes? Figuring out with Professor Alex Ellery.

What is cosmic dust? What is it made of and what can it tell us about the Universe? Could cosmic dust be responsible for life starting on Earth? Figuring it all out with Dr Craig Walton from Cambridge University.

We’ve learned what happened to the Odysseus Lander. SLIM survived the lunar night. Experience a fiery trip from orbit to the Utah desert. James Webb completes one of its major science goals.

How serious is the threat from space weapons? How should we handle the situation with international treaties? Is there a way to ensure the enforcement of them and what are the risks if somebody breaks them? Figuring out the answers with Dr Matthew Powell from the University of Portsmouth.

Where do auroras come from on rogue planets? Can we refuel the Sun to make it last longer? What's going on with space nuke tests? Answering all these questions and more in this week's Q&A show.

Odysseus lands successfully on the Moon, China is planning to build bricks on the lunar surface, James Webb finds the neutron star at the heart of supernova 1987 A, and Blue Origins finally rolls out New Glenn.

Why doesn't JWST look at Apollo landing sites? What happened to TRAPPIST-1 atmospheres? What's the biggest thing we can measure our velocity relative to? Will the Universe ever start bouncing back? Answering all these questions and more in this week's Q&A show.

Huge Kuiper Belt discovery! With James Webb astronomers were able to see that Eris and Makemake show signs of geothermal activity. How exactly did that happen? Figuring out with Dr Christopher Glein, Lead Scientist at Southwest Research Institute.

Solar sails aren't just a tool to send tiny spacecraft to Alpha Centauri. They can also be used to optimise exploration of the Solar System. How can we do that? Figuring it out with Alexander Alvara.

More oceans across the Solar System. The Event Horizon Telescope zooms into an active galactic nucleus. Another lunar lander sets off to the Moon.

What are the main problems of modern-day science? Why there's a growing trust gap between the scientists and the public? How can we fix those problems and restore the trust? Figuring out with Dr. Paul M. Sutter.

How sure can astronomers be when estimating asteroid strikes? Why is Jupiter so radioactive? What happened to the methane on Mars story? Are black holes 2D or 3D? Answering all these questions and more in this week's Q&A show.
