M92 Globular star cluster

 

27,000 light years away in the constellation of Hercules, M92 is one of the brightest and oldest globular clusters we know.

Tightly packed together it contains a mind bogglingly 330,000 stars, you know, give or take.

The German astronomer Johann Elert Bode is credited with the discovery of M92 in 1777.
