The release of the Gaia space telescope’s Early Data Release 3 has paved the way for a 3D map of the Milky Way, a glimpse at its history, and the acceleration of our own solar system. Plus, Alaskan volcanoes, the sound of a perfect fluid, bending light with the Sun, the Stingray Nebula fades, and yes, that really was a Centaur rocket booster captured by the Earth. And we announce our first CosmoQuest Book Club selection!
