Binary black holes spotted dining together near two merging galaxies

Two supermassive black holes found in the vicinity of a galaxy merger appear to be the closest pair found at different wavelengths, notes a recent study. Scientists discovered that the black holes were growing simultaneously near the center of the newly coalescing galaxy called UGC 4211. The "super-hungry giants," which lie 750 light-years apart, were devouring remnants resulting from the galactic merger.
