A massive star brightened in infrared light, then vanished without exploding. Astronomers uncovered the quiet birth of a ...
In the nearby Andromeda Galaxy, a massive star bright enough to stand out for years has gone dark. Not in a blaze of glory.
The James Webb Space Telescope and the Chandra X-ray Observatory have captured the clearest image yet of a galaxy cluster in the making, seen when the universe was only one billion years old.
Recent observations suggest that 'runaway' black holes are tumbling through the cosmos. Building on decades of theory, the discovery adds a remarkable new chapter to the story of the universe.
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 mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...
NASA’s NEOWISE has allowed astronomers to get the best and most complete view of a star collapsing into a black hole ever recorded.
Astronomers have captured one of the clearest views ever of a massive star dying—not in a dramatic supernova explosion, but ...
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 ...
