The eye of the Bull

Aldebaran is an orange giant that marks the eye of Taurus. Its warm color and brightness make it a standout of the winter sky and a useful signpost near Orion.

In front of the Hyades

Aldebaran appears among the V-shaped Hyades star cluster, but this is a line-of-sight effect: Aldebaran is much closer to us than the cluster and is not a member of it.

An evolved star

As a giant, Aldebaran has evolved off the main sequence, expanding and cooling at the surface to its characteristic orange glow — a later stage in a star's life than the Sun's current phase.
