Explanation: Careful inspection of the full field of view for this sharp composite (http://www.caelumobservatory.com/gallery/sky.shtml) image reveals a surprising number of galaxies both near and far toward the constellation Ursa Major (http://www.allthesky.com/constellations/ursamajor/). The most striking is clearly NGC 3718 (http://www.kopernik.org/images/archive/n3718.htm), a warped spiral galaxy found near picture center. NGC 3718's faint spiral arms look twisted and extended (http://antwrp.gsfc.nasa.gov/apod/ap060108.html), its bright central region crossed by obscuring dust lanes. A mere 150 thousand light-years to the right is another (http://panther-observatory.com/gallery/deepsky/ doc/NGC3718_cass.htm) large spiral galaxy, NGC 3729. The two are likely interacting (http://www.npaci.edu/online/v4.9/galaxies2.html) gravitationally, accounting for the peculiar (http://antwrp.gsfc.nasa.gov/apod/ap051008.html) appearance of NGC 3718. While this galaxy pair lies about 52 million light-years away, the remarkable Hickson (http://nedwww.ipac.caltech.edu/level5/Sept01/ Hickson/Hickson_contents.html) Group 56 can also be seen clustered just below NGC 3718. Hickson Group 56 (http://www.kopernik.org/images/archive/hick56.htm) consists of five interacting galaxies and lies over 400 million light-years away.
