M92 - Globular cluster In Hercules

Messier 92 is a globular cluster in the constellation Hercules. M92 is one of the brighter globular clusters in the northern hemisphere, but it is often overlooked by amateur astronomers because of its proximity to the even more spectacular Messier 13. M92 is at a distance of about 26,700 light-years away from Earth.
