Join EarthSky's Marcy Curran in a video preview of the #moon phases for March. There will be a total lunar eclipse of the full moon and a partial solar eclipse by the new moon this month. Also, the moon will visit Venus, Jupiter and Mars in the evening sky. Watch the video here! buff.ly/3EY44Oy

If you ask an astronomer when the first day of #spring is this year, they’ll say 9:01 UTC (4:01 a.m. CDT) on March 20. But if you ask a meteorologist or climatologist, they'll tell you spring starts March 1. How are there two different spring seasons? Read here: buff.ly/41bCy7q πŸ“Έ Pexels/ Pixabay.

EarthSky's RaΓΊl CortΓ©s caught dancing aurora in Lapland last night! The solar wind has been strong, leading to geomagnetic storming. Have you seen the aurora lately? πŸ”­ Keep up with the #sun news at buff.ly/4a84cpK

Tonight a slender waxing crescent #moon - only a little over a day old - will float above the western horizon about 30-40 minutes after sunset. Far above it, Venus will glow brightly. Look for bright Mercury close to the moon. Visit EarthSky’s night sky guide and watch a video at: buff.ly/3pjX4RP

Interesting! Scientists at a research station with the Max Planck Institute of Animal Behavior said they noticed something curious about wild #fish. The fish were able to recognize #human divers based on visual cues from their dive gear. 🐟🀿 buff.ly/41yutuU πŸ“Έ MPIAB/ MaΓ«lan Tomasek.

The last leap year was 2024. So 2028 will be our next leap year, a 366-day-long year, with an extra day added to our calendar (February 29). We’ll call that extra day a leap day. Why do we need the extra day? Blame Earth’s orbit. Read about leap years at: buff.ly/3uqy1iP πŸ“Έ NASA.

2025 has a lot of supermoons, and the 1st one – a new #supermoon – falls at 0:45 UTC tonight. We'll have 5 new supermoons in a row. Then we'll have 3 full supermoons in a row around the end of 2025. So … what’s a supermoon? πŸŒ•πŸ”­ buff.ly/47BuT3r πŸ“Έ Michael Flynn.

Meet the wooly devil! 😈 In March 2024, staff members of Big Bend National Park in Texas spotted a tiny #flower with fuzzy foliage they didn't recognize. On Monday, the National Park Service said the new #plant species is previously unknown to science. buff.ly/3EVFAW9 πŸ“Έ NPS/ D. Manley.

A minor geomagnetic #storm began this morning! Are any of you seeing #auroras? Solar wind speeds are rising due to coronal holes on the #sun. And we have a slight chance of additional geomagnetic storming in the coming 2 days. πŸ”­ Read the sun news: https://buff.ly/4a84cpK πŸ“Έ Spaceweatherlive.com.

New lunar lander #Athena is on its way to the #moon! At 7:17 p.m. EST last night, Intuitive Machines' 2nd mission successfully launched to the moon on a Falcon 9 rocket from Florida. The mission should arrive on the lunar surface in 1 week. πŸš€πŸŒ•πŸ”­ https://buff.ly/3XekMzt πŸ“Έ Greg Diesel Walck.

See some exciting new images from the #Lucy spacecraft! It's on a 4-billion-mile journey to explore a couple main-belt asteroids and 7 of Jupiter's Trojan asteroids.

Word is spreading that you can see all 7 #planets in the #sky together in late February and early March 2025. Want the truth? EarthSky's veteran stargazers Deborah Byrd, Marcy Curran and John Goss have your answer. πŸͺπŸŒŒπŸ”­ https://buff.ly/3CUbZfc πŸ“Έ EarthSky.org.

Hawaii is famous for its #rainbows. But when EarthSky's Kelly Kizer Whitt visited Haleakala National Park on Maui, Hawaii, last month, she saw a white rainbow, also called a #fogbow or ghost rainbow. Watch the video! 🌈 https://buff.ly/43cAPl3 And read about fogbows. https://buff.ly/49pb1mj

We reported an X flare yesterday, which came from the western (outgoing) edge of the #sun. And yesterday night, another #blast gave us a surprise! The event was an M3.9 flare. It probably came from the same sunspot region that produced the X #flare: https://buff.ly/4a84cpK πŸ“Έ SDO.

For the 1st time ever, astronomers have created a 3D map to study the weather on an alien #exoplanet. The exoplanet - called #WASP121b, aka Tylos - is a hot Jupiter found 900 light-years away in the direction of the constellation #Puppis the Stern. πŸŒŒπŸ”­ https://buff.ly/41hxJK4 πŸ“Έ ESO/ M.

Good news! On February 18, we were up to a 3.1% - or 1-in-32 odds - that #asteroid 2024 YR4 would hit #Earth on December 22, 2032. But as of today, the odds have dropped to 1-in-20,000. Why? πŸ”­ Read more: https://buff.ly/3PU8jwU πŸ“Έ EarthSky.org.
