Black Hole Discovered 12 Million Light Years From Earth


Scientists have discovered a black hole that is gulping the nearby stars. The research team reported that the speed at which the black hole is gobbling stars is almost 10 times faster than the previous estimations.

The discovery has been published in the journal Nature. Black holes are basically remnants of former stars. The black holes are so dense that nothing can escape from their powerful gravitational energy. According to scientists, the newly-found black hole named as P13, lies on the outskirts of the galaxy NGC7793, which is almost 12 million light years from earth.

International Centre for Radio Astronomy Research astronomer Dr. Roberto Soria said as gas emitted by the star falls towards a black hole it gets very hot and bright. Dr. Soria added that scientists were able to notice P13 because it was quite luminous than other black holes, but it was earlier assumed that it was bigger in size as well due to which it was easily visible.

Dr. Soria said, “It was generally believed the maximum speed at which black hole could swallow gas and produce light was tightly determined by size. So it made sense to assume that P13 was bigger than ordinary black holes seen in Milky Way”. After measuring mass of P13, Dr. Soria and his colleagues found that it was actually smaller than previously assumed, despite being million times brighter than the Sun.

Dr. Soria said that after analyzing the mass of P13, they realized how much material the black hole was actually consuming. There is no set limit for black holes, they can consume as much gas as they want and produce more light. In addition, Soria said P13 rotates around a supergiant ‘donor’ star, which is twenty times bigger than our own Sun. Also, P13 is a member of a select group of black holes known as ultraluminous X-ray sources. Adapted from: Maine News
