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