Wow! signal - Long far and ago away, a duo of dancing supermassive black holes appear to be spiraling in towards each other, eventually doomed to collide within a stupendous, almost unimaginable, cosmic smash-up. Dancing at nighttime, the strange pair will merge merely a million years from now, liberating energy equal to 100 million supernova blasts, by which massive stars perish. If not all, large galaxies in the Universe--including our own Milky Way--contain supermassive black holes with masses equivalent to millions, or even billions, of Suns, and these objects of incredible darkness and their host galaxies appear to evolve together, or "co-evolve", the dark-hearts of most. Theory predicts that as galaxies collide and in the end merge, growing a lot more massive as a result, so too do their hearts of darkness. Inside the January 7, 2015 issue in the journal Nature, a team of astronomers report on a weird repeating light signal from the distant quasar which they say is most probably the consequence of a duo of dancing supermassive black holes in the last act of a merger--something which is predicted from theory but which has never been seen before! A quasar is certainly a brilliant, luminous object that out-dazzles all the stars in its host galaxy combined, and it is visible from throughout the entire Universe!
