How Messier 13 (Hercules Globular Cluster) connects across Asteria Star — scientific, cultural, and astrological links are kept separate.
A catalogue of 110 deep-sky objects compiled by Charles Messier.
A dense, roughly spherical swarm of tens of thousands to millions of very old stars, tightly bound by gravity and orbiting in the halo of a galaxy. Globular clusters are among the oldest structures in the Universe, and their tightly packed, coeval stars make them benchmarks for stellar ages and the early history of the Galaxy.
