Mars and the Star Clusters
Explanation: At this year's end
Mars still shines brightly in
planet Earth's night as it wanders through the head-strong constellation Taurus. Its bright yellowish hue dominates this
starry field of view that includes Taurus' alpha star Aldebaran and the Hyades and Pleiades star clusters. While
red giant Aldebaran appears to anchor the
V-shape of the Hyades at the left of the frame, Aldebaran is not a member of the Hyades star cluster. The Hyades cluster is 151 light-years away making it the nearest established open star cluster, but Aldebaran lies at less than half that distance, along the same line-of-sight. At the right, some 400 light-years distant is the open star cluster
cataloged as Messier 45, also known as the Pleiades or Seven Sisters. In Greek myth, the Pleiades were daughters of the
astronomical titan Atlas and sea-nymph
Pleione.
