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

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

A supermassive black hole in J1007+3540 has roared back to life after 100 million years, firing jets across nearly one million light years and revealing a turbulent battle inside a galaxy cluster.

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.

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 ...

A supermassive black hole roughly 11.6 billion light-years from Earth is consuming matter at 13 times the theoretical maximum rate, forcing astrophysicists to reconsider how these cosmic giants grew ...

An unusual tidal disruption event spotted by astronomers may be the result of an elusive intermediate mass black hole ripping ...

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.

During the survey, researchers identified a promising 8.19-millisecond pulsar (MSP) candidate located close to Sagittarius A*, the supermassive black hole at the center of our galaxy.

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

The KM3NeT collaboration is a large research group involved in the operation of a neutrino telescope network in the deep ...

A ‘runaway’ black hole ejected from its host galaxy is barrelling across space — and leaving behind a wake of newborn stars.
