NGC 457 - ET Cluster
aka Owl Cluster
Open Cluster NGC 457 had been termed the Owl Cluster, but later earned the name E.T. cluster subsequent to the popular movie E.T. Can you see the two large eyes above the thin body angled top left to bottom right with the widely stretched arms? The "eyes" are formed by the double star Phi Cassiopeia, whose fifth and seventh magnitude components are separated by 1.34 arc seconds. The eyes are about 2,000 light-years distance while the rest of the cluster is about 10,000 light-years away. Scattered near the cluster and throughout the image are several red giant stars.
