Description

NGC 457 is an open cluster in Cassiopeia, also called Owl Cluster due to its particular shape: in fact it is characterized by the presence of two bright stars of sixth magnitude from which a concatenation of stars that resemble the wings of a bird in flight starts; the two bright stars are the "eyes" of the owl. 
The cluster is made up of about sixty stars and is about 8000 light years away: it is a young cluster, having an estimated age of around 21 million years. 
Countless far galaxies are visible in the background.
