Spitzer, Hubble, and Chandra image of Arp 26, also known as M101 or the Pinwheel Galaxy.
In the infrared light Spitzer view we see a network of yellow-green of dust lanes. In the visible light Hubble view, the dust is dark and blue star clusters dot the spiral arms. In the X-ray Chandra view, we see million-degree gas, supernova remnants, neutron stars, and black holes.
