Details:
Messier 4 (also designated as M4 or NGC 6121, and occasionally referred to as the Spider Globular Cluster) is a prominent globular star cluster located in the constellation Scorpius, roughly 7,200 light-years away from Earth. Situated just 1.3 degrees west of the bright red supergiant star Antares, it holds historical significance as the first globular cluster in which individual stars were successfully resolved. Discovered by Philippe Loys de Chéseaux in 1745 and later cataloged by Charles Messier in 1764, M4 features a distinctive "bar" structure of brighter stars spanning across its core and is noted for containing some of the oldest known white dwarf stars in our galaxy.
