Astronomers watch a massive star collapse into a black hole without a supernova
SMRTR summary
Astronomers observed a massive star in the Andromeda Galaxy collapse directly into a black hole without exploding as a supernova, providing the most detailed view ever of stellar black hole formation. The star dramatically faded over several years as convection processes caused its outer layers to slowly spiral into the newly formed black hole rather than fall straight in, creating a lingering infrared glow.
