Description
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.

Hertzsprung Gap
Ready for some adventure in your life? Cross the Hertzsprung gap. If a star can jump across several spectral cloud masses in a relative blink of an eye, you can absolutely make the leap across the Hertzsprung gap and leave that run of the mill main sequence behind. And while you're on your way to the bright lights of the red giant branch, you can marvel at the pulsating glow from the instability strip. So if you're looking for a change of scenery, take a hop, skip, and a jump over the Hertzsprung gap to brighten up your life. The Hertzsprung gap, for every generation there's a gap (Gap).
