Located 27,000 light-years from Earth in the constellation Hercules, this globular cluster — a ball of stars that orbits our galaxy’s core like a satellite — was first discovered by the German astronomer Johann Elert Bode in 1777. With an apparent magnitude of 6.3, M92 is one of the brightest globular clusters in the Milky Way and is visible to the naked eye under good observing conditions. It can be most easily spotted during the month of July. The cluster is very tightly packed with stars, containing roughly 330,000 stars in total.
