M44: The Beehive Cluster

M44 is a beautiful open cluster in the center of the constellation Cancer. It can be seen as a faint nebulosity with the naked eye under good viewing conditions, and is easily resolved with a small pair of binoculars or telescope. In fact, this is one object frequently better suited for binoculars compared to a telescope, due to its large angular extent. Distance estimates for this cluster vary from 500-600 lightyears away, but astronomers are fairly confident in an age of about 600 million years old.
