This galaxy, NGC 17, represents a merger that appears to be complete. It features a single nucleus, containing a blue central disc with delicate fine structure in the outer parts and tidal tails indicative of two former disc galaxies. The remnant shows clear signs that the merger was gas-rich and accompanied by a starburst. It is located about 250 million light-years away in the constellation Cetus, the Whale.
