"Using a combination of instruments on ESO’s Very Large Telescope, astronomers have discovered the most massive stars to date, one weighing at birth more than 300 times the mass of the Sun, or twice as much as the currently accepted limit of 150 solar masses."
Star 136a1 is the most massive star found yet. Since the time of Pierre Laplace, astronomers have believed that stars condensed from rotaing clouds of gas. How such clouds could become dense enough to start nuclear fusion has been a nagging puzzle. This immense star challenges the old theories.
If stars formed around tiny Black Holes, the inward pull of the singularity would cause the star to condense until fusion began. Presence of the singularity would allow stars to form with enormous sizes, hundreds of times our Sun's mass. The centre of star 136a1 would be a good place to find a Black Hole.
