Two dots, one bigger and brighter (Venus) than the other (Saturn) in a bluish and orangish sky. There is a city below.

Juan Manuel Pérez Rayego captured #Venus and #Saturn yesterday, after sunset, from Mérida, Spain, and wrote: "Bright Venus and Saturn to its lower left, with an airplane and its trail above them. Thank you, Juan Manuel!

A new large coronal hole has emerged from the eastern horizon of our #sun. As it moves into a geoeffective position in the next days, the fast solar wind it produces will be sent our way, disturbing our magnetic field and potentially triggering #auroras. Stay tunned:

In May 2024, the biggest solar storm recorded in 20 years hit Earth. It sent our planet’s atmosphere into overdrive, triggering #auroras. This storm also hit Mars. Read about what happened on the Red Planet at: buff.ly/unepnU8

Aurora borealis glows green over snowy Finnish forest and cabins beneath a clear starry night sky.

A G1 (minor) geomagnetic storm brought gorgeous #auroras to high northern latitudes last night. EarthSky’s own C. Alex Young - a sun scientist and co-author of EarthSky's daily sun update - got to see them! More of Alex's photos here, along with tonight's prospects: buff.ly/WNDBg5Z

At 2 a.m. today, clocks in most U.S. states and many Canadian provinces leapt forward one hour. #Daylightsaving time (DST) began. Don’t like daylight saving time? Blame New Zealand entomologist G.V. Hudson.

Star chart: 2 ladle-shaped patterns of stars, with an arrow between them pointing from the Big Dipper to Polaris.

The Big Dipper's "pointer stars" help you spot #Polaris, the North Star. The #BigDipper is an easy-to-locate star pattern visible from the Northern Hemisphere. Both it and the Little Dipper look like big dot-to-dots of a kitchen ladle.

Star chart showing the three constellations that formed the ancient Argo Navis—Carina, Vela, and Puppis—with bright stars Sirius and Canopus labeled.

The #constellation of Puppis the Stern was once part of a much-larger constellation named Argo Navis, the Ship. In the 1700s, Nicolas Louis de Lacaille divided the Ship into 3 constellations. They are Puppis the Stern, Carina the Keel and Vela the Sails. 🔭 Read more about Puppis at: buff.ly/bGRE1RL

Oval map of near side of the moon. The yellow spots mark ridge-adjacent small mare ridges and the red spots mark standalone small mare ridges.

When #asteroid 2024 YR4 was first discovered, in December 2024, there were only a few observations to draw from. But yesterday, NASA said new Webb observations have allowed scientists to safely rule out a lunar impact in 2032. Read more: buff.ly/5ndMhgF

Water bears on Mars: Wrinkly, kind of oval-shaped creature with no eyes and 6 stubby legs with claws.

It's the Jellyfish #Nebula! Andrew Stone in Cave Creek, Arizona, captured it last month and wrote it's a ... “galactic supernova remnant in the constellation Gemini, roughly 5,000 light-years from Earth." Thank you, Andrew!

Sky photo with many stars and the Winter Hexagon outlined, its stars and a few more objects labeled.

Throughout history, humans looked at the stars and saw mythical beings, beasts and cultural touchstones. Our #constellations provide links to our ancestors. But most #asterisms - patterns within a constellation or stars in multiple constellations - are relatively new. 🌌🔭

Why do female #caribou have #antlers? Males in many #deer species grow antlers, but not females. Only female caribou have them. Now, a new study says the antlers of female caribou are a crucial source of nutrition, especially for mothers with newborn calves. 🦌

A rocky body in space with debris trailing behind. Bold white text says 'Life forms could planet-hop on asteroids, study finds'.

Interesting! Tiny lifeforms in debris from an #asteroid impact could catapult to other planets and survive. A certain #bacterium can withstand extreme pressure comparable to an ejection from Mars after an asteroid hit, and survive the interplanetary journey. 🦠🔭
