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 .
