Cool clouds of dust that fill the space between the stars in the Milky Way glow in infrared light and tell us more about the story of how stars are born, and how they die. The bright stars of the constellations fade into obscurity amongst the backdrop of millions of other stars revealed by WISE. However, WISE observed infrared light, where the sky takes on a very different appearance. To the unaided human eye, Cassiopeia is easily recognizable by the five bright stars that make up its "W" shape. These constellations, named after an ancient Queen and King of Ethiopia in Greek mythology, are visible in the northern sky every night of the year as seen from most of the United States. The constellations Cassiopeia and Cepheus are featured in this 1,000-square degree expanse. This enormous section of the Milky Way galaxy is a mosaic of images from NASA's Wide-field Infrared Survey Explorer, or WISE.
