Today’s Astronomical Events – June 16th, 2015

Messier 6, aka the Butterfly Cluster, is one of several that’s easily spotted by observers in the southern and mid-northern latitudes (unfortunately, it’s too far south to be seen by those in the United Kingdom.) If you’re lucky enough to see the whole of Scorpius, you may be able to glimpse the cluster with just your eyes, close to the sting of the scorpion itself.

The cluster is about half the size of its neighbour, Messier 7. Binoculars should reveal a number of faint stars, like granules of sugar in a triangular pattern, but the best views will always come through the eyepiece of a telescope. Even at low power the cluster can be spectacular, with the butterfly shape being easily seen and hundreds of tiny stars catching the eye of the patient observer.
