Astronomers Watch a Massive Star Collapse Into a Black Hole without a Supernova

Astronomers watch a massive star collapse into a black hole without a supernova

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 slow-motion cosmic fade-out. The leftover debris continues to glow in infrared light, offering a long-lasting signal of the black hole’s birth. The finding reshapes our understanding of how some of the universe’s biggest stars meet their end.

Scientists Capture the Clearest View Yet of a Star Collapsing Into a Black Hole: an event astronomers have anticipated for decades, but have had limited evidence for. The star appears to have undergone direct collapse, turning into a black hole without fi

Scientists Intrigued as Prominent Star Suddenly Winks Out of Existence

The end of a star’s life can be an extremely violent event. Once it runs out of fuel, its core collapses, and if its original mass is large enough, it can erupt in a supernova, a runaway nuclear fusion event that can release as much energy as the Sun will produce over its entire lifespan of roughly ten billion years. The remains are either a neutron star, an immensely dense lump of matter, or a black hole. Now, scientists believe they may have o…

Astronomers document star’s vanishing act in rare ‘failed supernova’

Astronomers have captured what they describe as the most complete observational record of a massive star disappearing in what researchers interpret as a collapse into a black hole, without the dramatic supernova explosion that usually marks such stellar deaths.

How can a star collapse without exploding?

A stealthy route to black hole birth Astronomers have captured what appears to be a star that vanished by collapsing directly into a black hole rather than exploding as a supernova. This “failed supernova” scenario was long predicted by theory but rarely observed; the new record used archival…

Supergiant Star Collapsed into Stellar-Mass Black Hole in Andromeda Galaxy

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 and vanishing into a black hole -- an event once theorized but rarely seen.
