After decades of study, scientists sound genuinely optimistic about the possibility of detecting primordial black holes, which might explain dark matter.

Space-time may hide a bizarre new kind of black hole that causes Einstein’s theory of gravity to fail – and could solve the ...

Researchers in South Korea are developing a constellation of satellites that could reveal what goes on in the vicinity of supermassive black holes like never before.

Black holes are interesting and fascinating objects in the universe. They are highly dense areas of space where gravity is so ...

A small black hole would plunge straight into the event horizon, while a normal star would quickly be torn apart by tidal forces. But astronomers theorize that a low-mass white dwarf, a compact ...

A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be?

Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle ...

Strange x-ray pulses hint at a surprisingly long-lived white dwarf orbiting precariously close to a supermassive black hole ...
