Messier 80 is a very pretty globular cluster located in the constellation of Scorpius. It can be seen with a good pair of eyes and a basic telescope. M80 is estimated to be 32,600 light years away, whilst being about 95 light years in diameter. It is one of the more densely populated globular clusters in the Milky Way. An interesting fact about this cluster is that it contains a relatively large number of so called “Blue Stragglers”, which stars that appear to be much younger than the cluster itself.
