M-92 (NGC-6341)

M-92 (NGC-6341) is a large, bright globular star cluster in the constellation of Hercules. If it were not overshadowed by the spectacular globular M-13, it would be considered a showpiece. It was discovered by Johann Bode in 1777, and added to Charles Messier's catalog the same year as number 92. M-92 lies 9 degrees to the NE of M-13. This cluster has a much more dense structure than M-13, with a highly compressed, blazing core, which is equalled by few other globular clusters. It lies 26,000 light years from Earth, and is 110 light years in diameter.
