Scientists from the European Space Agency’s Planck and Herschel missions along with their colleagues at NASA have put together this map of the entire sky (universe). The black dots that are spread out in the universe are locations of potential galaxy clusters.  These were first discovered by Planck and subsequently observed by the European Space Agency’s Herschel mission. The lighter, grey coloured band running through the middle of this picture corresponds to dust in our Milky Way galaxy.
