Details

Messier 92 is a globular cluster of stars in the northern constellation of Hercules.
M92, is among the largest, oldest and brightest globular clusters in the Milky Way.
It was discovered by Johann Elert Bodein 1777. It was inadvertently rediscovered by Charles Messier on March 18, 1781.
It is one of the brighter of its sort in apparent magnitude in the northern hemisphere.
It is visible to the naked eye under very good viewing conditions.
Like most globular clusters, the predominant elements within M92 are hydrogen and helium.
Successive generations of stars cook up the heavier elements in their cores, which in astronomy are all considered metals.
Globular clusters like M92 are thus considered to be ‘metal-poor’.
