PASADENA, CALIF. (June 8) — The most massive black hole yet weighed lurks at the heart of the relatively nearby giant galaxy M87.
The supermassive black hole is two to three times heftier than previously thought, a new model showed, weighing in at a whopping 6.4 billion times the mass of the sun. The new measure suggests that other black holes in nearby large galaxies could also be much heftier than current measurements suggest, and it could help astronomers solve a longstanding puzzle about galaxy development.
