The latest map of Everything

In infrared, this is what Everything looks like. The map of the whole sky was compiled by NASA’s infrared space telescope, WISE, and is made up of 560 million stars, galaxies and other objects.

The Milky Way’s disk and central bulge are traced out in blue, representing infrared light with a wavelength of 3.4 micrometres, which mainly comes from stars.

The bluish blobs to the bottom right are our two largest satellite galaxies, the Large and Small Magellanic clouds, more than 150,000 light years away. Andromeda forms a small blue streak to the lower left, and the image is dotted with more distant galaxies. Learn more here or here.
