Map of the Hyades Map of the Hyades

An open star cluster so close to the Earth (just 150 light years) that it was only recognised as a cluster in the twentieth century. The stars of the Hyades form the V-shaped 'face' of Taurus, the Bull, and lie behind the bright star Aldebaran, which is much closer to our Solar System.
