A massive star brightened in infrared light, then vanished without exploding. Astronomers uncovered the quiet birth of a black hole.

Astronomers watched a massive star in the Andromeda Galaxy vanish over a decade, providing rare evidence of a "failed supernova" forming a black hole without exploding.

In the nearby Andromeda Galaxy, a massive star bright enough to stand out for years has gone dark. Not in a blaze of glory.

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 ...

Using archival data from NASA’s NEOWISE mission along with data from other space and ground-based observatories, astronomers identified the clearest observational record yet of a massive star fading ...

A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...

It is easy to observe when stars explode in a supernova and become a black hole. It is different when they simply collapse.

One of the brightest stars in the Andromeda galaxy quietly collapsed into a black hole without any of the fanfare of a spectacular supernova.

A “disappearing” star in the Andromeda galaxy is the closest and best candidate for a newborn black hole that astronomers have ever seen ...

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 ...

Scientists have captured the moment a supergiant star collapses into a black hole, revealing the star's death in an ...
