Scientists Find Huge Black Holes

American scientists have found the biggest black holes known to exist. Each one of these black holes is ten billion times bigger than the size of our sun. A team led by astronomers at the University of California, Berkeley, discovered the two gigantic black holes in clusters of elliptical galaxies more than 300 million light years away. That's considered to be relatively close to Earth on the galactic scale. The previous black hole record-holder is as large as six billion suns. Black holes are objects so dense that nothing, not even light, can escape. Source
