A distant quasar is defying two fundamental expectations of black hole physics. The object, known as ID830, is growing at 13 ...

An ancient, fast-feeding quasar is breaking the rules of how black holes consume matter and generate galaxy-shaping jets.

A burst of X-rays from 8 billion years ago may be the first clear evidence of a white dwarf torn apart by a black hole.

Learn how supermassive black holes may be suppressing star formation in nearby galaxies.

Scientists have long suspected that active supermassive black holes can kill their own host galaxies, but new research suggests these cosmic titans are more like serial killers that can extend their ...

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...

An exotic type of dark matter could explain some of the characteristics of our galaxy’s central supermassive black hole, but ...

Last year, astronomers were fascinated by a runaway asteroid passing through our Solar System from somewhere far beyond. It was moving at around 68 kilometres per second, just over double Earth&rsquo ...

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

If confirmed, this disappearing act might provide the closest and best observational evidence for the birth of a black hole ...

A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes. The star cluster in question is called Palomar 5. It's a stellar ...

Astronomers report a supergiant star in the Andromeda Galaxy, M31-2014-DS1, collapsed directly into a black hole without a supernova, confirming predictions of failed stellar explosions.
