The team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s ...

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 ...

Astronomers tracked a star in Andromeda as it dimmed and vanished without the usual fiery explosion, offering rare clues to how black holes form.

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.

Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's ...

Astronomers combing through years of images collected by the NEOWISE mission have found the clearest known evidence of a star converting directly to a black hole, without passing through the supernova ...

DS1, collapsed into a black hole without exploding, revealing how stars die in silent “failed supernova” events.

"Measuring the properties of neutron-star matter is indeed very hard and this is because while we can measure the mass of a neutron star very accurately, it is very hard to measure its radius ...

A stellar black hole is one that’s created from the gravitational collapse of particularly massive stars, typically greater than eight solar masses. For context, one solar mass is about equivalent to ...

New simulations suggest magnetic fields hold the key to forming black holes that defy known mass limits. When powerful magnetic forces act on a collapsing, spinning star, they eject vast amounts of ...
