Messier 72 (also known as M72 or NGC 6981) is a globular cluster in the Aquarius constellation discovered by Pierre M?chain in August 29, 1780. Charles Messier looked for it on the following October 4 and 5, and included it in his catalog. Both decided that it was a faint nebula rather than a cluster.
Using 10-inch (250 mm) telescopes, viewing the cluster is difficult resulting in only a view of a faint blurry picture, However using Kopernicks 20-inch (510 mm) telescope resolution is highly increased.
M72 is located at about 53,000 light-years away from Earth and lies in a considerable distance beyond the galactic center. Another source states that the cluster is 62,000 light-years away, with a diameter of 42 light-years. Generally considered a young cluster, the cluster has several blue giants, yet star clusters generally contain the oldest stars.
