Black Holes Discovered in Star Cluster M62
Scientists discovered a black hole in a collection of stars in the constellation Ophiuchus, which is about 22000 light years from Earth. The globular cluster in which black hole was spotted is known as M62. The globular cluster M62 is located in the constellation Ophiuchus.The discovery was done by the team of astronomers led by a Michigan State University professor. Black holes are stars that have died, collapsed into themselves and possess such a strong gravitational field that even light cannot escape from them.Prior to this discovery, astronomers had assumptions that the black holes did not exist in globular clusters- some of the oldest and densest collections of stars in the universe.There are numerous stars in such a condensed area that they often interact with one another. Massive black holes will have most violent encounters.
