Midnight in late autumn, you can appreciate constellations of winter at eastern sky.
You'll pay attention a group of several stars gathering cozy and a "V" shaped asterism a bit looser.
They are open clusters of the Pleiades and the Hyades respectively, and the cluster of Hyades forms the face of Bull, the Taurus.
The Hyades includes a bright and reddish star of Aldebaran that looks like bull's eye being bloodshot. The constellation shows mainly the horns of bull, The southern horn starts from Hyades and extends to zeta Tauri, and another one of north lifts up just north of the Hyades, through to beta Tauri, that is part of Auriga. The rest of the bull is rather faint, a slight body and two spindle legs. |
