An international team of scientists have detected a huge black hole with a mass 70 times larger than the Sun, which is believed to be the biggest individual stellar black hole that has been discovered in our galaxy till now.
The discovery was announced in the latest issue of Nature on Thursday morning.
The newly found black hole, located 15,000 light years from Earth has been named BL-1.
Scientists said the size of BL-1 is impossible to form in the Milky Way and its finding might challenge the existing models of how stars evolve, and lead to a new class of black holes.
might challenge the existing models of how stars evolve
Current standard stellar evolution models appear to be consistent with the formation of black holes upto 70 Msun at high metallicity, but unable to explain how a binary star system like LB-1 could have formed without invoking some exotic scenarios.
HD 188753 is a hierarchical triple star system approximately 151 light-years away in the constellation of Cygnus, the Swan. In 2005, an extrasolar planet was announced to be orbiting the primary star (designated HD 188753 A) in the system. Follow-up measurements by an independent group in 2007 did not confirm the planet's existence.
