Star Orbiting a Medium Sized Black Hole
Astronomers have found evidence of monstrous black holes at the heart of galaxies with the mass of millions of stars, or ones with just the mass of a single star. But not much in between (100 to 10,000 stellar masses). One of the newest pieces of evidence for a medium-sized black hole was captured by NASA’s Chandra X-Ray Observatory. It measured the orbit of a star trapped in a death spiral around one of these medium-mass black holes.
