LOS ANGELES (February 27, 2013)--Using two space telescopes, an international team of scientists measured the rotation of a nearby gigantic black hole and discovered that it's spinning at close to the speed of light.
Astronomers have long suspected that supermassive black holes in the center of galaxies rotate faster and grow larger as they feed on gas, dust, stars and matter, but until now there hasn't been a reliable measurement of the spin rate.
Scientists say it's hard to know how fast the giant black hole in the Milky Way is spinning because it's not as active as the one they observed.
The study was published in Thursday's issue of the journal Nature.
