Astronomers spotted one of the biggest black holes ever found sitting in a cosmic backwater.
The black hole contains 17 billion times the mass of the sun and is making researchers question their ideas about where gigantic black holes reside and how many there may be.
"The black hole is much bigger than we expected for the size of the galaxy or where this galaxy lives, the environment," said study co-author Chung-Pei Ma, an astronomer at the University of California, Berkeley.
