Scientists discover largest black holes ever recorded
Astronomers have recorded the biggest black holes ever detected — a pair of stellar monsters that somehow have managed to swallow the equivalent of 10 billion suns each.
“That’s a fairly healthy diet,” said James Graham of the University of Toronto, who is at a loss to explain how they grew so massive.
One of the black holes has a mass of 9.7 billion suns and lurks in the elliptical galaxy NGC 3842, the brightest galaxy near the Leo constellation 320 million light-years away.
