   Explanation: It is the closest cluster of stars to the Sun. The
   [4]Hyades [5]open cluster is bright enough to have been remarked on
   even thousands of years ago, yet is not as bright or compact as the
   [6]nearby Pleiades (M45) star cluster. Pictured here is a particularly
   deep image of [7]the Hyades which has brings out vivid [8]star colors
   and faint coincidental nebulas. The brightest star in the field is
   yellow [9]Aldebaran, the eye of the bull toward the [10]constellation
   of Taurus. [11]Aldebaran, at 65 [12]light-years away, is now known to
   be unrelated to the [13]Hyades cluster, which lies about 150
   light-years away. The central [14]Hyades stars are spread out over
   about 15 light-years. Formed about 625 million years ago, [15]the
   Hyades likely shares a common origin with the [16]Beehive cluster
   (M44), a naked-eye open star cluster toward the [17]constellation of
   Cancer, based on [18]M44's motion through space and remarkably similar
   age.
