Taurus  (The Bull)

  • Just northwest of Orion, Taurus is an outstanding northern constellation containing two of the largest Open Clusters – The Hyades and The Pleiades, also known as The Seven Sisters -both striking groups of stars.
  • In the sky, the Hyades Cluster marks the bull’s face, while the red giant star (Aldebaran) forms the creature’s bloodshot eye.
  • Our Sun passes through Taurus from 14 May to 21st June every year.

Messier Objects

  • M1  –  Supernova remnant; it was seen from Earth in AD 1054 – detectable in binoculars under good conditions, rather faint (around magnitude: +9.0).
  • M45  – Open Cluster; also known as Messier 45 (M45), Seven Sisters or The Pleiades, large and bright – easy to see with the naked-eye and superb sight through binoculars. Under perfect condition, the reflection nebulosity around Merope (NGC 1435) maybe glimpsed with large binoculars.

Features of Interest

  • Hyades  –  Open Cluster; known as Melotte 25 (Mel25), the second closest open cluster, stars appears spread over a considerable area of the sky and its moving cluster – the star Aldebaran appears to be a member, but is in fact much closer to us and not part of the cluster.
