On the morning of Tuesday 22 July look toward the southeastern horizon for the waning crescent Moon to be in the ‘V’ of the open star cluster known as the Hyades, and about 2o away from the reddish star Aldebaran.. The v-shaped Hyades marks the face of Taurus the Bull with Aldebaran representing a red eye, an angry bull.
The Hyades is a an open star cluster with somewhere around 200 stars many of which help form the familiar v-shape pattern. Unmistakable in its brightness compared with the rest of the ‘v’ stars is the reddish star Aldebaran. While Aldebaran is usually described as the eye of the bull this red giant star is not actually part of the open cluster. Rather it is a line-of-sight arrangement. Aldebaran (60 light years) is nearly three times closer than the stars of the Hyades (150 light years).
