Black hole born without a bang in neighboring galaxy
A research paper argues that a star in the Andromeda galaxy collapsed into a black hole after failing to go supernova
TL;DR
- A massive star in the Andromeda galaxy has become a black hole without a supernova.
- This event challenges previous scientific understanding of how massive stars die.
- The star, M31-2014-DS1, exhibited unusual changes in infrared brightness before nearly vanishing.
- Researchers theorize that ejected matter did not have enough velocity to escape the black hole's gravity.
- The faint infrared glow from a surrounding dust cloud and future X-ray observations may confirm the theory.
- This quiet stellar death offers valuable insights into stellar physics.
