Ancient Black Hole Speeds Through Sun's Galactic Neighborhood, Devouring Companion Star

February 9, 2005
Data from the Space Telescope Science Institute's Digitized Sky Survey has played an important supporting role in helping radio and X-ray astronomers discover an ancient black hole speeding through the Sun's galactic neighborhood. The rogue black hole is devouring a small companion star as the pair travels in an eccentric orbit looping to the outer reaches of our Milky Way galaxy. It is believed that the black hole is the remnant of a massive star that lived out its brief life billions of years ago and later was gravitationally kicked from its home star cluster to wander the Galaxy with its companion.
