NGC 6144

NGC 6144 is a globular cluster in the constellation Scorpius, located almost exactly 1° away from the much brighter globular cluster Messier 4.[5] It is close by and is partially obscured by Rho Ophiuchi cloud complex.[4] The cluster has a very low core stellar density for a globular cluster and harbors a few X-ray radiation sources.[6]
