This is the beautiful open star cluster M44, also called Beehive Cluster or Praesepe. It's a relatively close star cluster, only about 600 light years away from us. M44 contains about 1000 stars, with 700 of them being red dwarfs, almost 300 sun-like stars and 20 bright and blue A-type stars. The proper motion of the star cluster suggests that it has been part of the Hyades, the closest star cluster to earth.
