Astronomers observed the supermassive black hole in galaxy NGC 3783 ejecting ultra-fast winds after a powerful X-ray flare.

A new ultramassive black hole has been discovered, and we’re not even going to try to get our heads around its scale. The enormous object observed for the first time is 30 billion times bigger than ...

A sudden black hole flare unleashed stunning, near light speed winds that echo the Sun’s most powerful eruptions.

Scientists have confirmed that colossal collisions between galaxies trigger titanic eruptions in the centers of those galaxies, and the discovery is thanks to an artificial intelligence tool that was ...

A supermassive black hole has astonished astronomers after it was observed blasting out powerful winds raging at roughly one-fifth the speed of light. Two X-ray observatories, the European Space ...

A team of astronomers including George Washington University physics Ph.D. student Eliza Neights recorded an extraordinary ...

Dusty stars close to the Milky Way’s black hole stay stable for years. New infrared data shows they survive gravity and ...

This infrared view offers the clearest look yet at how dwarf galaxies merge, evolve, trade gas and ignite waves of new stars.
