M4 Globular Cluster
M4 was the first globular cluster to be resolved as a cluster of stars by Charles Messier. When viewed with a moderate size telescope, the individual stars within M4 will be visible. It it easy to locate M4. About one degree to the west of the brightest star Antares in the constellation Scorpius, M4 appears as a fuzzy ball of light as seen in a small telescope. Located only 7,200 light-years away, M4 is the one of closest globular clusters to our solar system. With an estimated age of 12.2 billion years, stars within M4 are much older than our Sun, about 4.5 billion years old.
