The first quarter Moon appears close to the orange giant star Aldebaran, in the constellation of Taurus the Bull. The star marks the red eye of the bull itself and appears on the edge of the Hyades open star cluster, a V-shaped group of stars best observed with binoculars. For observers in the United Kingdom, the Moon will appear in the midst of these stars in the evening sky tonight.
