From orbit, star trails streak the lights of cities at night and stamp lightning flashes into the time history, pulling spectacular colors from the darkness of space.
Our first image of Betelgeuse's companion star revealed ⭐
This is NASA's discovery of a close-orbiting star to Betelgeuse, the 10th brightest star in our night sky. A @nasaames scientist confirmed the century-old hypothesis by using one of the largest ground-based telescopes in the world paired with a high-resolution camera built by NASA.

A two-for-one special! ✨
In this 2016 image, the galaxy NGC 3274 glitters from 20 million light-years away.
Located even farther, the galaxy PGC 213714 is also visible in the upper right: https://t.co/MzG0IbzFVN
The fabulous Lagoon Nebula (M8) is a large, kaleidoscopic emission nebula located about 4,000 light years away in Sagittarius. Comprised primarily of ionized hydrogen, the nebula is about 55 light years wide and energized by the nearby young star, Herschel 36. 📷 John Nemcik #M8
More than a hundred galaxies can be seen in this image of Abell 209 – but there’s even more to this galaxy cluster! 🤯 A more elusive part of it is dark matter: a form of matter that does not interact with light. 1/3
Our #HubbleTopImage features a star among galaxies! 🤩
Messier 77 is one of the most famous galaxies, with more papers written about it than many other galaxies put together! However, it has twice been the victim of mistaken identity… 1/3
NGC 3982 is an elegant face-on intermediate spiral galaxy located about 68 million light years distant in Ursa Major. Discovered in 1789 by William Herschel, this beautiful galaxy is adorned with pink star-forming regions and newborn blue star clusters. 📷 NASA #NGC3982
