Three merging galaxies host three active black holes, offering rare insight into galaxy and black hole growth.

In a remarkable breakthrough, astronomers have uncovered the first known triple system where three galaxies, each harboring ...

In a patch of sky about 1. 2 billion light-years from Earth, astronomers have found a cosmic rarity: three galaxies caught in ...

Three galaxies were found in the merger of a triple system, which was rare in itself, and might help observe hierarchical ...

A new discovery about what happens when a supernova – an exploding star – and a black hole collide could change the way scientists understand the lives and deaths of stars. The finding was the first ...

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) ...

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 ...

WASHINGTON (Reuters) -Astronomers have observed the calamitous result of a star that picked the wrong dance partner. They have documented what appears to be a new type of supernova, as stellar ...

A black hole that was eaten by a star seems to have gotten revenge by consuming the star from the inside, producing a gamma-ray burst spotted about 9 billion light-years from Earth. The burst, called ...

Astronomers have confirmed the first known triple system in which all three galaxies host actively feeding, radio-bright ...

A proposed interstellar mission envisions sending a gram-scale nanocraft, propelled by a laser-driven lightsail to a nearby black hole, achieving approximately one-third the speed of light. Upon ...
