Prepare to be amazed by the celestial wonders on December 27, 2025! The night sky will offer a captivating sight, but here's the twist: it's all about a happy face in the stars. Yes, you read that right!
On this date, the stars align to form a delightful asterism known as the Happy Face in the constellation Auriga. Imagine a celestial smile gracing the eastern sky, with two eyes, a nose, and a broad grin. But wait, there's more to this cosmic spectacle!
Start your stargazing journey with Auriga's brightest star, Capella (magnitude 0.1), and then venture 8.7° south-southeast to Sigma Aurigae. From there, a short hop of 1.7° southeast leads you to the open cluster M38, a stunning sight at magnitude 7.4. Through binoculars or a telescope, you'll witness a cluster spanning 20', with its brighter stars forming the Greek letter pi (π). But here's where it gets intriguing: M38 is part of the Happy Face asterism, forming a dimple in this celestial grin, along with the star Phi Aurigae (magnitude 5.1).
And this is the part most people miss—the Happy Face isn't the only treat in Auriga. Just 2° southeast, you'll find the open cluster M36, a youthful gathering of stars at magnitude 6.3. These clusters are like cosmic jewels, waiting to be discovered by curious sky enthusiasts.
For those eager to plan their stargazing adventure, here are the precise times for this locale (40° N 90° W):
- Sunrise: 7:21 A.M.
- Sunset: 4:42 P.M.
- Moonrise: 12:02 P.M.

But the sky doesn't stop surprising us there! On the same night, the moon's shadow and its moon, Io, will cross Jupiter's disk, adding to the celestial spectacle. And if you're wondering what else the sky has in store, check out our full Sky This Week column for more cosmic delights.
