In this episode of The AstroGuy Podcast, Wayne walks you through everything unfolding in the December 2025 night sky, one of the best observing months of the year thanks to long, dark winter nights and crisp, steady air. We start with a full planetary roundup, including Jupiter’s stunning December performance, Saturn’s nearly edge-on rings, and a look at Mercury’s early-morning apparition. We also cover the ongoing activity from Comet Lemmon, the fragmented C/2025 K1 ATLAS, and the rare interstellar visitor 3I/ATLAS, along with clear explanations of what it is, and what it isn’t.
December brings two meteor showers, with the Geminids once again offering the year’s most reliable performance, and the Ursids providing a second chance for shooting stars under dark skies. In space news, we discuss NASA’s ESCAPADE mission and Blue Origin’s major landing milestone, along with the final chapter for Japan’s Akatsuki Venus orbiter.
This month’s Lunar Feature spotlights the Bay of Rainbows a favorite target for lunar observers. Then we wrap up with a deep-sky tour through Taurus, highlighting Aldebaran, the Pleiades, the Hyades, and the spectacular lunar occultation of M45 on December 3rd and MORE.
Whether you’re observing with binoculars, a telescope, or just your winter coat and a clear sky, December has something worth getting outside for.
