Astronomers have
discovered a giant black hole that is surprisingly heavy in relation to the
galaxy hole live in. Super Heavy black holes in galaxies are typically several
million times heavier than our Sun. But now, astronomers have found a black
hole that is 17 billion times more massive than the Sun! The giant black hole
at the heart of a galaxy called NGC the 1277th.
The enormous black hole
is possibly the heaviest astronomers have ever found - it is also certainly the
second-heaviest. The astronomers namely previously found a black hole that is
between 6 and 37 billion times more massive than the Sun. If this black hole
turns out to be at the low end of this range, then it will be the black hole in
NGC 1277 can be titled as the heaviest.
The most surprising
thing about the black hole in NGC 1277 is not that it is so heavy, but that it
is unusual significance in view of the galaxy, it lives in. Normally,
supermassive black holes approximately 0.1% of the total mass of their galaxy,
but for the black hole in NGC 1277, this figure is as much as 14%. The
researchers are now investigating other galaxies to see if the huge black hole
in NGC 1277 is the exception that proves the rule. If several similar examples
will be found, astronomers could be forced to fundamentally rethink their
theoretical models of how galaxies and their supermassive black holes are
formed and evolve.
