SPACE - Astronomers measure most massive, most unusual black hole

Astronomers have used the Hobby-Eberly Telescope at The University of Texas at Austin's McDonald Observatory to measure the mass of what may be the most massive black hole yet-17 billion Suns-in galaxy NGC 1277. The unusual black hole makes up 14 percent of its galaxy's mass, rather than the usual 0.1 percent. This galaxy and several more in the same study could change theories of how black holes and galaxies form and evolve. The work will appear in the journal Nature on Nov. 29.
