The night sky is shifting this week as Venus and Mercury take their leave from the evening sky—at least for now. Jupiter shines in Taurus, Mars lingers near Gemini’s twin stars, and Leo rises high, showcasing its dazzling triplet of galaxies.

Speaking of cosmic wonders, a listener wrote in with a great question: Why do astronomers say “water ice” instead of just “ice”? We break it down, from Martian polar caps to the frozen landscapes of Europa and Enceladus.

Then, we take a look at the Pleiades, a stunning open star cluster best viewed with binoculars, and the mighty Leo Triplet, a trio of galaxies locked in a cosmic dance. And don’t forget—March 20th marks the Spring Equinox!
