  1. A study using NASA's Swift satellite and the Chandra X-ray Observatory has found a second supersized black hole at the heart of an unusual nearby galaxy already known to be sporting one.

    Viewed in visible light, Markarian 739 resembles a smiling face, with a pair of bright cores underscored by an arcing spiral arm. The object is really a pair of merging galaxies. Data from Swift and Chandra reveal the eastern core (left) to be a previously unknown AGN; past studies already had identified an AGN in the western core. The two supermassive black holes are separated by about 11,000 light-years. The galaxy is 425 million light-years away. (Credit: Credit: SDSS)
