    The black hole heavyweight of the nearby universe could be an even heftier behemoth than previously believed. Now, using a supercomputer at The University of Texas at Austin, astronomer Karl Gebhardt and colleagues have re-run the numbers that suggest the supermassive black hole at the heart of the giant galaxy M87 weighs the same as 6.4 billion suns — two to three times heavier than previous estimates. The new estimate suggests that a large bulk of the mass initially thought to belong to stars at M87′s core is actually locked up in the halo at the galaxy’s outer edge.
