The photo for the week of February 7, 2008 is titled NGC 4013 and the Tidal Stream. This so called isolated universe, NGC 4013, is located 50m light-years in the circumpolar constellation of Ursa Minor. Previously unknown, a dust loop around NGC 4013 has just been discovered. This universe was previously classified as flat with a central star bulging from it. The loop has a diameter of 160 thousand light-years. It appears that smaller stars are being gratitationally pulled toward this universe.
