Incredible dancing "corona" aurora filmed in real-time during an intense geomagnetic storm. Location: Fairbanks, Alaska

This time-lapse technique that makes you truly feel that it's not the sky that's spinning, but the Earth rotating—it's amazing.

In the rare case you haven’t seen it yet:
Here is the 10-day trajectory of Artemis II around the Moon and back.
It follows a figure-eight loop around the Moon, reaching over 230,000 miles away from Earth.

Halley's Comet, as depicted in the Bayeux Tapestry. The comet was seen over the skies of England in April of 1066

More than 400 years ago, Galileo Galilei proposed that mass does not affect the speed with which an object falls. Now, using the world's largest vacuum chamber at NASA, we can confirm this fundamental principle of physics. xitter.cf/i/status/2031710479748…

⚡️This is the clearest image ever taken of Saturn’s North Pole.
A perfect hexagonal storm is raging for decades now and it is over 30,000km across.
First spotted by Voyager 1 back in 1980s.

Almost a thousand years ago, someone carefully embroidered a fiery comet on a long strip of linen. I love the expressions of the guys pointing at it, and the man informing King Harold.
It was Halley's Comet, which orbits the Sun every 76 years. The linen is the Bayeux Tapestry, and the comet was seen as a bad omen causing wars, famines and the death of kings.
It's named for British astronomer Edmond Halley, but it had been seen and recorded for thousands of years prior, including an elderly monk, Eilmer of Malmesbury, who noted the 76-year reappearance in 1066.

Glow mode: activated. ✨🌍
From the International @Space_Station, green auroras ripple across Earth as charged particles from the Sun collide with atmospheric gases, guided by our planet’s magnetic field. The thin orange glow marks the edge of our atmosphere — a reminder that Earth is alive, protected, and glowing.
