Explanation:
Many
stars like our
Sun were formed in
open clusters.
The above open cluster,
M11, contains thousands of stars and is just over
three thousand
light years distant.
The stars in this cluster all formed
together about 150 million years ago.
The bright young stars in
M11 appear blue.
Open clusters, also
called galactic clusters, contain fewer and younger stars than
globular clusters.
Also unlike globular clusters,
open clusters are generally confined to the plane of
our Galaxy.
M11 is visible with binoculars towards the constellation of Scutum.
