Walkabout the Galaxy

Aug 31, 2022

We take a journey to the Radius Valley to explore an exoplanet larger than the "Super Earths" and smaller than Neptune and Uranus. This one in particular is interesting not only because of its unusual size but also its composition appears to have a huge amount of water that may be in liquid form. We'll also check in with Up Quark Hannah Sargeant in the Artemis Corner, and cover a lot of space news and trivia.
