Today’s Astronomical Events – April 17th, 2015

M3 (Messier 3) is a globular cluster found about halfway between Cor Caroli, the brightest star in Canes Venatici and Arcturus, the brightest star in the constellation Boötes. Located nearly 34,000 light years away, it is thought to be about 8 billion years old and contains roughly half a million stars.

The cluster is fairly large, reasonably bright and can be found using binoculars or a telescope.
