The Andromeda galaxy in far-infrared
This far-infrared image of M31, the Andromeda galaxy, was taken by the Herschel Space Observatory on Feb. 6, 2013. Star-forming regions of gas with temperatures barely above absolute zero are shown in orange, while slightly warmer, older stars in the central bulge are shown in blue.

There’s as many atoms in a single molecule of your DNA as there are stars in the typical galaxy. We are, each of us, a little universe.
