The Great Hercules Globular Cluster—one of the most famous objects in the night sky—can be seen overhead in late evening for the next couple of weeks. From a dark site, this cluster appears as a faint fuzzy patch between the bright stars Vega in the constellation Lyra (and part of the Summer Triangle asterism), and Aructurus in the constellation of Boötes. It is also known as "M13" because it is the 13th object in a famous catalog compiled by the 18th-century comet hunter Charles Messier.
