Today’s Astronomical Events – April 11th, 2015

Despite having passed opposition (and its best visibility for the year) a few months ago, Jupiter is still a bright object in the early evening sky and can be used to locate M44, the Beehive (aka the Praesepe) star cluster. 

A fine sight in binoculars and telescopes at low power, the Beehive is a famous cluster that’s been known since ancient times. It can be easily seen from rural locations but under city skies it’s often lost in the light pollution. Fortunately, Jupiter and the Beehive can currently be seen close together with binoculars. With Jupiter on the left (eastern) edge of  the field of view, the Beehive should appear on the far right (western) edge.
