Winter is on its way when the Pleiades star cluster pokes above the horizon in the late evening sky. At the centre of the constellation is the prominent V of the 'head of the bull'. As well as the jewel box of the Pleiades, or M45, Taurus contains the Hyades, another big star cluster of which the prominent Aldebaran, the 'eye of the bull', is actually not a member. Charles Messier's first listed deep sky object, the Crab Nebula, a supernova remnant, lies close to one of the end 'horn' stars.
