The article “Milky Way’s monster black hole is the heaviest ever found by Gaia” reports that astronomers have discovered the heaviest black hole in the Milky Way galaxy using data from the European Space Agency’s Gaia spacecraft. The black hole has a mass that is 70 times greater than that of the Sun, making it the largest stellar-mass black hole ever found in our galaxy.
This groundbreaking discovery was made by a team of researchers led by a scientist named Daniel Michalik, using data gathered by the Gaia spacecraft, which mapped the positions and velocities of over a billion stars in the Milky Way. The black hole, known as LB-1, is located about 15,000 light-years away from Earth in the constellation of Sagittarius.
According to the article, the discovery of this massive black hole challenges current theories of black hole formation, as it is much heavier than expected. The researchers believe that LB-1 may have formed from the collapse of a giant star or by merging with other black holes.
The findings of this study have been published in the journal Nature Astronomy, and have generated excitement among the scientific community, as it sheds light on the mysterious and enigmatic nature of black holes in our galaxy. The discovery of LB-1 opens up new possibilities for further research and exploration of these cosmic phenomena.
