, called "antares". You see, astronomers in the East and the West happen to coincide. M7 open cluster M7 is one of the most famous open clusters in the sky. This cluster has many bright blue stars. At night, we can see it from the tail of Scorpio with the naked eye. M7 is about 1000 light years away from us, and consists of about1000 stars, with an age of about 200 million years and a size of about 25 light years. The above color photo was recently taken by the Kitt Peak National Observatory in Arizona, USA, and it is part of the Advanced Observer Program. As early as ancient times, people began to know about the M7 open cluster, which Ptolemy observed in 130. You can also see the dark dust clouds at the bottom of the constellation frame and millions of stars in the center of the Milky Way that have nothing to do with clusters.
