Galaxy Clusters, Blue Stars and Cosmic Explosions
Cassiopeia and Cepheus
The constellations Cassiopeia and Cepheus are featured in this mosaic of images taken by NASA's Wide-field Infrared Survey Explorer, or WISE. Named after an ancient Queen and King of Ethiopia in Greek mythology, these constellations are visible in the northern sky seen in most of the United States. The image shows cosmic star-forming clouds, bubbling with the birth of new stars, and blowing out stardust.
