See twisting #solar plasma and magnetic fields whirling into space in yesterday's immense filament explosion. 💥

Nothing's coming our way from it ... but there's a huge #sunspot facing Earth, capable of throwing out big flares. Will it?

🪐 Planets have family types, too! And astronomers say there are 2.

Turns out, a planet’s family depends on its home #star. ⭐

These insights might help us know where to look to find life in the galaxy! 🌎

Hi stargazers!

Tonight, just after sunset, watch for the waxing crescent #moon hanging close to the bright star #Antares in Scorpius. They’ll be easier to spot – farther from the sunset – the farther south you are on Earth. 🌒🌌

What is the closest star to our sun? It's #ProximaCentauri! 🌌

It isn’t visible to the eye. Yet it’s one of the most noted #stars in the heavens. Why? Because it’s part of the #AlphaCentauri system, the closest star system to our sun. There are 3 stars in the system.

Did you see a weird cloud from the U.S. East Coast yesterday morning? ☁️

It was a #SpaceX #Falcon resupply mission to the #spacestation, which created a gorgeous plume of light called a jellyfish. 🪼 🚀

Meet Aquarius, the Water Bearer! 🌌💧

#Aquarius is a #constellation located between #Capricornus and #Pisces, best viewed under dark skies. And now is one of the best times of the year to spot it! ✨

Here's when and where to look:

Have you ever seen the Beehive Cluster through a #telescope? Here’s what it looks like with red Mars shining against its stars! Will you give it a try tonight? 🔴🌌 🔭

Tameem Altameemi in Dubai caught red #Mars shining in front of the #Beehive star cluster on Monday morning. Thank you!

Auroras possible tonight!

A stream of fast solar wind is currently billowing from the sun to Earth. Plus, a great burst of solar material might glance our planet later today. Combined, this could trigger #auroras at northerly latitudes. Will you see them from your location?

Moon challenge! 🌙

Can you spot the young crescent moon after sunset? It's trickier in the Northern Hemisphere in autumn, when the moon sits low on the horizon. In the Southern Hemisphere, spring brings a better view!

Bonus: spot bright red star Antares nearby.

Meet the weirdest #cloud on Mars! ☁️🔴

This giant formation appears near the Martian volcano Arsia Mons every spring and summer. It grows and stretches out, then fades away again each day. But what causes this strange behavior? “Exotic physics.”

Amazon #wildfires destroy trees and release CO₂. But a new study reveals another, invisible threat: ozone. The same gas that protects us from UV radiation high in the atmosphere harms trees and human health near the Earth's surface. Find out more:

#Auroras tonight? A burst of solar material could graze Earth today! 🌞🌍

The incoming solar material could trigger a G1 (minor) geomagnetic storm, with a chance of reaching G2 (moderate) or even G3 (strong) levels! Read our #sun news:
