Hubble has spent 35 years in orbit! Celebrate with an array of compelling images recently taken by Hubble: Mars, dramatic views of stellar birth and death, and a magnificent spiral galaxy: bit.ly/4jjsAs7

Ooh! NASA’s Lucy spacecraft flew by asteroid Donaldjohanson yesterday. They just released the images.

Look at that cool space potato! 🥔

Did you find the #StarWars world, Tatooine, and its companion stars impressive? Then check this! 😉

ESO's Very Large Telescope (VLT) has discovered the first planet that not only orbits a pair of stars but does so at an angle of 90 degrees.

Both stars are brown dwarfs, objects bigger than gas-giant planets but too small to be proper stars. When tracking their orbits, astronomers found that the orbits themselves change over time. After carefully ruling out other explanations, they concluded that the gravitational tug of a planet in a polar orbit was the only way to explain the motion of the brown dwarfs.

"Big surprise": astronomers find planet in perpendicular orbit around pair of stars

Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these ‘polar planets’ orbiting a stellar pair. The surprise discovery was made using the European Southern Observatory’s Very Large Telescope (VLT).

Ground-based image of Arp 25, also known as NGC 2276.

NGC 2276 (left) is being pulled by the neighboring galaxy NGC 2300 (right). NGC 2276 is rich in new star formation along its spiral arms. The companion, NGC 2300, consists of aging yellow-white stars and lacks any spiral arm structure.

NGC 2276 Wide-Field

This pair of galaxies are close enough together they are in a "tug of war" as they pass close enough to feel each other's gravitational pull. This is evident in the lopsided appearance of the blue galaxy on the left, NGC 2276. It is being pulled by the neighboring galaxy on the...
