Description: Messier 92 (also known as M92 or NGC 6341) is a globular
cluster in the constellation Hercules. It was discovered by Johann Elert
Bode in 1777 and independently rediscovered by Charles Messier on March
18, 1781. M92 is at a distance of about 26,700 light-years away from
Earth.
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. It is visible to
the naked eye under very good conditions (text from en.wikipedia.org/wiki/Messier_92)
