BH1 and Gaia BH2

  • Scientists have made a groundbreaking discovery by finding the closest black hole to Earth.
  • BH1 is the closest black hole ever detected till date.
    • It is situated just 1,560 light-years away from Earth in the direction of the constellation Ophiuchus.
  • It was discovered by a team of astronomers using the European Space Agency’s (ESA) Gaia satellite, which is designed to precisely measure the positions and movements of stars in the Milky Way
  • In addition, Gaia also found the second closest black hole to Earth, Gaia BH2, which is 3800 light-years away in the constellation Centaurus.
  • Black holes are formed when massive stars collapse under the force of their own gravity, creating incredibly dense objects.
    • They are so dense that their gravity is strong enough to trap anything that comes too close, including light itself.
