Using two NASA satellites, astronomers have discovered the heftiest known black hole to orbit a star.The new black hole, with a mass 24 to 33 times that of our Sun, is more massive than scientists expected for a black hole that formed from a dying star.
The newly discovered object belongs to the category of "stellar-mass" black holes.
Formed in the death throes of massive stars, they are smaller than the monster black holes found in galactic cores.
The previous record holder for largest stellar-mass black hole is a 16-solar-mass black hole in the galaxy M33.
The black hole is located in the nearby dwarf galaxy IC 10, 1.8 million light-years from Earth in the constellation Cassiopeia.
