Supermassive black holes spiral towards each other in this simulation created by NASA's Goddard Space Flight Center that shows how they glow in ultraviolet and X-ray light. The black holes are only 40 ...

Astronomers were puzzled by a black hole around 50 million times the mass of the sun with no stars, spotted by the James Webb Space Telescope – now simulations suggest it could be a primordial black ...

When astronomers look deep into the early universe, the expectation is simple. You should see young galaxies still assembling ...

The Hubble Space Telescope has imaged a "200,000 light-year-long trail of newborn stars" that may have been left behind by a ...

The first black hole images stunned the world in 2019, with headlines announcing evidence of a glowing doughnut-shaped object from the center of galaxy Messier 87 (M87 —55 million light years from ...

If dark stars existed, they would have been capable of forming in the universe before ordinary stars could have formed. When ...

Nearly every galaxy has a supermassive black hole in its core. Whether the black hole forms first and then the galaxy around ...

A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

Everything about the Infinity galaxy is unusual. It looks very strange and it has a supermassive black hole pulling a lot of ...

New simulations suggest magnetic fields hold the key to forming black holes that defy known mass limits. When powerful magnetic forces act on a collapsing, spinning star, they eject vast amounts of ...

A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen object called a black hole pulsar. When you purchase through links on our site, ...

Some of the most puzzling worlds in our telescopes’ catalogs may not be worlds at all, but relics from the first instants ...
