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

The event horizon of a nonspinning billion-solar-mass back hole has a radius of 1.8 billion miles — the distance of Uranus from the Sun.

Astronomers have traced the origins of an unusual cosmic formation resembling a musical treble clef to an ancient black hole ...

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 ...

Researchers have used radio observations of rapidly spinning neutron stars to search for signals from supermassive black hole pairs at the dawn of galaxy formation.

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

Back in 2018, an array of telescopes spotted something extraordinary in the night sky, a still-unexplained explosion larger ...

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

Space is a scary place. Certainly, many objects in it appear scary to our human brains, and we interpret their shapes as ...
