The red planet, Mars, sails through the beautiful cluster of stars known as the Beehive this week. Catalogued as Messier 44, the cluster lies in the constellation Cancer. It has been known since antiquity, when its hazy appearance earned it the Latin name Praesepe, meaning a manger or crib.
Although it is one of the brightest star clusters in the night sky, it can be surprisingly difficult to locate because Cancer contains no bright stars to guide the eye towards it. Thankfully, this week Mars acts as the signpost.
