James Webb detects carbon dioxide on the surface of Europa. A full metal exoplanet. Searching for tiny dyson spheres. And learning how black holes eat so quickly.

Have astronomers found the first signs of life on an exoplanet? So much James Webb news. The closest black hole to Earth. NASA gives its report on UAPs.

What's going on with the Hubble Tension and does it really imply a Crisis in Cosmology? How to stay sceptical but at the same time keep an open mind? What big discoveries should we expect in the coming future? Looking for answers to all these questions with Dr Ethan Siegel.

Starship could be almost ready to fly. The smallest possible Mars colony. Three more space missions launched this week. And a new look at China’s next-generation crew capsule and lunar lander.

The center of our Galaxy is a mystery. It is full of dust which most telescopes can't see through. But with James Webb we can look into it. What hides deep in the middle of the Milky Way? Finding out with Dr Adam Ginsburg.

Which JWST image is the best so far? To answer that, we did a series of polls among our community with a quarter-final round, semi-final and the final. Can my fellow space YouTubers guess which one turned out to be the winner? Do they agree with your decision? Let's find out!

An exoplanet denser than steel. The Whirlpool Galaxy from JWST. We finally learn where the solar wind comes from. The ISS is getting gigabit internet.

There is a disagreement in measurements of the Hubble constant often referred to as The Crisis in Cosmology. One way to solve it is to observe redshift drift. However, it requires lengthy observations. But my guest, Dr Geraint Lewis, has a hack up his sleeve — gravitational lensing.

India lands on the Moon. Another Ring Nebula image from JWST. One of the coolest exoplanet videos you’ve ever seen. New images of Neptune.

The farthest star and the farthest galaxy seen by JWST. Measuring the darkness of the Universe from deep space. New evidence for MOND vs dark matter.

Superconductor update. Contact re-established with Voyager 2. Two stars orbiting so closely they could hide inside the Sun. A field of gravitational lenses in a new JWST image.

Classical space telescopes have their limit. You can't simply build bigger mirrors all the time. Instead, you can build more mirrors and combine them into a telescope array. That's the concept behind the Nautilus Array which we discuss with Prof. Daniel Apai from The University of Arizona.

NASA Loses Contact with Voyager 2 because of a mistake. Euclid sends its first images. Finally, The Ring Nebula from JWST.

Dealing with space debris is an increasingly important aspect of spaceflight. Can we take it under control? What technical challenges will we need to overcome? What will it mean for the future of space infrastructure? Answering all these questions with Alex Godfrey from Astroscale.

What will it take to ditch chemical rockets and make space launches fully electric? What tech will it require and when will it be reasonable to use such a system? What technical challenges are associated with it? Answering all these questions with David Dillon, the founder of Electromagnetic Launch.

NASA reveals nuclear rocket partnership with Lockheed Martin. Witnesses claim there’s a UAP coverup. There could be trillions of rogue planets wandering the Milky Way.
