Among the most unimaginable: "Two black holes most massive ever found, astronomers say" December 5, 2011 7:53 pm bowser

“The mass of each is about 10 billion times the mass of our sun. The previous black hole record holder, first measured in 1977, has a mass of about 6 billion suns.

“And for each black hole, the “event horizon” – basically areas from which nothing can escape their gravity – is about five times the distance between our sun and Pluto.”
