NGC 7331, 45 million Light-Years Away

Caption

NGC 7331 is a luminous edge-on spiral galaxy about 45 million light-years away in the constellation Pegasus. If we could view our own Milky Way galaxy from the outside, it might look very similar to this NGC 7331 galaxy. At left and center, respectively, are Swift images captured through the Ultraviolet/Optical Telescope's optical and ultraviolet filters. The panel at right shows X-ray observations (0.2-10 keV) from Swift's X-ray Telescope.
