Collisions between stars in the early universe were common, and this could explain the growth of supermassive black holes and ...

Gravitational wave detectors have revealed that black holes frequently collide, in the process merging to produce larger ...

Scientists have discovered a possible loophole in the laws that normally prevent black holes from splitting apart, suggesting that extremely fast-spinning black holes might divide into two. The ...

In our solar system's corner of the galaxy, stars rarely collide. It makes sense: Space is vast, and stars have room to roam.

Nov. 6, 2026 After nearly 22 years of exploring the universe’s most violent explosions, NASA’s Swift Observatory has re-entered Earth’s atmosphere over Indonesia. Originally designed to last just two ...

The giant black holes in the Markarian 501 galaxy complete one orbit in just 121 days. Astronomers have estimated when they might collide.

Astrophysicists think that the supermassive black holes (SMBH) we see in the modern universe are the result of a long, ...

Black holes sometimes merge. But could 1 split into 2 or more? A new study explores the conditions that might allow it, ...

James Webb observations of Little Red Dots suggest ultra-dense star clusters merging into giant black holes shortly after the ...

After more than two decades of observing some of the universe's most powerful explosions, NASA's Neil Gehrels Swift ...

Astronomers have discovered a star being torn apart by a massive black hole more than 1,000 parsecs from the center of its host galaxy. The tidal disruption event, TDE 2023mfm, was first discovered by ...

An apparently modest cosmic explosion produced one of the brightest afterglows astronomers have seen in two decades.
