Astronomers have discovered what may be the most massive black hole ever known in a small galaxy about 250 million light-years from Earth, scientists say.
The supermassive black hole has a mass equivalent to 17 billion suns and is located inside the galaxy NGC 1277 in the constellation Perseus. It makes up about 14 percent of its host galaxy's mass, compared with the 0.1 percent a normal black hole would represent, scientists said.
"This is a really oddball galaxy," said study team member Karl Gebhardt of the University of Texas at Austin in a statement. "It's almost all black hole. This could be the first object in a new class of galaxy-black hole systems." . . .
