Encyclopedic overview
NGC 4013 is an edge-on barred spiral galaxy about 55 million light-years away in the constellation Ursa Major. The disk of NGC 4013 shows a distinct "peanut"-shaped bulge in long exposure photographs that N-body computer simulations suggest is consistent with a stellar bar seen perpendicular to the line of sight.
Infrared image of the galaxy showing a ring of heavy star formation A recent deep color image of NGC 4013 revealed a looping tidal stream of stars extending over 80 thousand light-years from the Galactic Center. This structure is thought to be the remnants of a smaller galaxy that was torn apart by tidal forces as it collided with NGC 4013.
