The planets are less dense than expected, suggesting they are not purely rock but half-rock and maybe half-water. Plus, star factories in the Milky Way, glaciers on ancient Mars, and This Week in Space History.

Climate Change Melts Glaciers, Greens the Arctic

As global temperatures rise, Earth observations show that glaciers are retreating and ice sheets are melting everywhere from Greenland to Antarctica while regions of the Arctic are getting greener. Plus, collaborations lead to new Mars and exoplanet discoveries, several rockets launched, and this week’s What’s Up involves Dr. Brian May of Queen.

SEASON PREMIERE: Catching up on news and rockets!

As we return from our summer hiatus, we are back with a rundown of some of the stories that came out during the break. On the planetary front, JWST has been taking amazing images and learning about exoplanets. On the astrophysics front, we’ve got stories on dark matter and Betelgeuse. And there were thirty orbital launches, including a whole lot of Starlinks… but not including Artemis.
