Giant black hole in tiny galaxy confounds astronomers (BBC) talks about the supermassive black hole at the center of galaxy NGC 1277, "220 million light years away in the constellation Perseus." Scientists studying the movements of the stars orbiting it have weighed NGC 1277's central supermassive black hole at about 17 billion solar masses—"4,000 times larger than the one at the Milky Way's centre [aka Sagittarius A*—which is mentioned in the article : )]." NGC 1277's black hole is so big that the event horizon is as large as our solar system, and accounts for 14 or 15% of its galaxy's total mass, which they say is 100 times larger than the usual ratio of supermassive black hole mass to total host galaxy mass—that's the other thing, that NGC 1277 is a somewhat small, old galaxy, so the current theories don't really explain how such a galaxy gets what may currently be the second largest known supermassive black hole inside of it.

I'm thinking galactic collisions, but who knows!

Selenis takes up luge but aren't you supposed to go feet first?
I think black holes are the Universe's vacuum cleaners.
