Quite a fascinating region of space:

"An international team of astrophysicists, led by D. Hudson from the University of Bonn and including the U.S. Naval Research Laboratory and the University of Virginia, presents their X-ray detection of a proto supermassive binary black hole."

"A pair of supermassive black holes in the distant universe are intertwined and spiraling toward a merger that will create a single super-supermassive black hole capable of swallowing billions of stars...Sarazin's team found that the two merging supermassive black holes in Abell 400 appear to be swallowing gas from their host galaxy, and each is ejecting a pair of oppositely-directed jets of radio-emitting plasma. As the supermassive black holes fall through the gas in the cluster Abell 400, jets of radio-emitting plasma are swept back behind them."

Nothing like two black holes battling it out.
There are some incredible X-Ray images of this region available on other sites as well.
