M2
NGC 7089


Globular Cluster
This globular cluster was discovered by Maraldi in 1746 while observing a comet
with astronomer Jacques Cassini.  Our boy Messier 'rediscovered' it  in 1760 but he
thought it was as nebula without any stars persay.  Boy, was he wrong.  Bill Herschel,
in 1783 resolved the star issue and there we are.

M2, is about 37,500 light-years from earth, it is also some 175 light-years across. It is
tight, rich, elliptical and some  13 billion years old. With over 100,000 stars

It is understandable why Messier has this bad boy high on his listing.
