A commercial robotic spacecraft called LINK launched on an emergency mission to save NASA’s Neil Gehrels Swift Observatory, which has been slowly falling toward Earth, on July 3, 2026. Over the coming weeks, LINK, built by Katalyst Space Technologies, will try to grasp the telescope, then spend months raising it to a safer orbit.

The Whirlpool galaxy (M51) is a classic grand spiral galaxy. It was the first object identified as a spiral, way back in 1845. At the time, it and other galaxies were considered spiral nebulae, since astronomers didn’t know other galaxies existed. Edwin Hubble finally proved that there were other galaxies in the early 1920s.

A black hole may be stirring a “pot” of gas containing a neighboring galaxy in the early universe, according to a new study published in Astronomy & Astrophysics that used observations from NASA’s Chandra X-ray Observatory. The galaxy slowly being “cooked” is named MQN01 J004131.9-493704, but astronomers have nicknamed it the “red potato” because of […]

Mysterious high-speed “bullets”—clumps of possibly oxygen-rich gas traveling at up to 20 million miles per hour—have been discovered shooting out of the rarest stellar explosion in our galaxy.

The star that formed the Jellyfish nebula may have had a partner star that exploded 100,000 years earlier, according to international researchers, who say that this may be the first known discovery of a binary star system in which both stars have gone supernova.
