Astronomers Discover Largest Stellar Black Hole in the Milky Way, Just 2,000 Light Years Away

Named Gaia BH3, the black hole's massive size of 33 solar masses was identified using data from the ESA's Gaia spacecraft.

  • Gaia BH3 is the largest known stellar black hole in our galaxy, significantly surpassing the mass of others.
  • It was discovered through its gravitational effects on a nearby companion star, which revealed its presence.
  • The black hole and its companion star likely originated from a metal-poor progenitor, shedding light on stellar evolution.
  • Despite its proximity, Gaia BH3 is dormant, posing no immediate threat to Earth.
  • This finding is part of ongoing research that could unveil more such black holes in future Gaia data releases.
