Astronomers have discovered a black hole lying just 1,000 light-years from Earth. The black hole is closer to our solar system than any other found to date and forms part of a triple system that can be seen with the naked eye. The astronomers found evidence for the invisible object by tracking its two companion stars using the MPG/ESO 2.2-meter telescope at ESO's La Silla Observatory in Chile. They say this system could just be the tip of the iceberg.
