The plane of our Galaxy runs horizontally across the image.
Sources are color coded by their infrared colors.
Blue sources are cool stars within our Galaxy, which show an obvious concentration to the galactic plane and center. Yellow-green sources are galaxies which are basically uniformly distributed across the sky, but show an enhancement along a great circle above the galactic plane. This enhancement is caused by galaxies in the Local Supercluster. Reddish sources, the infrared cirrus, are extremely cold material close to us in our own Galaxy. The map was produced with an Aitoff projection.
