Description

Messier 92 (NGC 6341) is a globular cluster of stars in the northern constellation of Hercules.

M92 is at a distance of about 26,700 light-years away from Earth and has an estimated mass of up to 330,000 solar masses in 250,000 stars.

With an estimated age of 14.2 billion years – almost the same age as the universe itself – M92 is one of the oldest clusters known and possibly the single oldest globular in the Milky Way.
