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.

It's already been one year of JWST operations. In this episode, we accumulated all the major science results, all the amazing images and graphs, all the important discoveries and controversies. Enjoy the ULTIMATE GUIDE to the first year of James Webb.

A white dwarf was found that literally has to sides. One is Hydrogen. The other one is Helium. And it constantly rotates and changes those two sides. What's going on and how could this possibly happen? We're figuring it out with Dr Jeremy Heyl from the University of British Columbia.

Is the Universe twice as old as we thought? China updates its lunar exploration plans. Astronomers might have found an exoplanet in a Lagrange Point.

Enceladus is the most interesting world in our Solar System in terms of exploration potential. It just is. But at the moment there are no approved missions to come back there. In this interview I'm discussing a New Frontiers class mission concept, the Astrobiology eXploration at Enceladus (AXE) with Dr Marshall Seaton from NASA JPL.

James Webb recently celebrated its first anniversary at work. What science results did it bring? Why graphs of spectra are as great as the nice pictures? How did JWST change Cosmology? What to expect from the next year of observations? All the answers in this Special Episode.
