During December you can watch for some impressive shooting stars and spend some time with the “Demon Star,” which can’t decide how bright it wants to be. Bundle up, grab your curiosity, and head outdoors for this month’s fun and informative Sky Tour. Read more: buff.ly/bv8vyWH Sponsored by Celestron

This week Comets C/2025 A6 Lemmon and C/2025 R2 SWAN will both be passing their closest to Earth and will probably be at their brightest. Lemmon should be about 5th magnitude, SWAN about 6th. Both are in binocular range in a good sky. . . #astronomy #stargazing #comet #CometLemmon #CometSWAN

The low waxing Moon passes the head of Scorpius. The best view will actually be in a darker sky than this, near the end of twilight: maybe 75 minutes after sunset. But you'll need a clear horizon in this direction. skyandtelescope.org/astronomy-ne... . . #astronomy #stargazing #scorpius #moon

On these dark evenings the Perseus Double Cluster and the Andromeda Galaxy, M31, await in the northeast. They're only two fist-widths apart. skyandtelescope.org/astronomy-ne... . . #astronomy #stargazing #doublecluster #starcluster #galaxy #andromedagalaxy

With just a one-minute setup and no technical skills required, students can explore the universe with Unistellar’s smart telescopes. And with NASA and SETI as their partners, the science behind it is as real as it gets. Learn more at buff.ly/94rMnzV and @unistellar.bsky.social

A surge of asteroids might have peppered the inner solar system some 800 million years ago, in a short-lived shower that left its mark — literally — on Earth and its neighbors. skyandtelescope.org/astronomy-ne... . . #astronomy #moon #asteroids #craters

In eight days Saturn will be at opposition. So now's the time to carefully examine the brightness of Saturn's nearly edge-on rings — to compare with how they bright they will appear right around opposition date. skyandtelescope.org/astronomy-ne... . . #astronomy #stargazing #saturn
