Scientists discover closest black hole to earth in a naked-eye-visible star system just 1,000 light years away.

  • The star system is location in the Telescopium constellation.
  • The black hole’s two bright companion stars helped astronomers pinpoint the black hole’s location.
  • The two companion stars can been seen with the naked eye in the southern hemisphere,. “We were totally surprised when we realized that this is the first stellar system with a black hole that can be seen with the unaided eye.”
  • Scientists noted that one of the stars was rotating around an invisible object every 40 days. This led scientists to recognize they were seeing a triple star system that included the two stars and the black hole.
  • The observation was made using the MPG/ESO 2.2-meter telescope at the European Southern Observatory’s La Silla Observatory in Chile.
