Night Sky Update
The object of the week for May 6 is an asterism called the Engagement Ring. First off we should explain what an asterism is. Asterisms are the informal patterns of stars as opposed to the constellations which are the formal groupings of stars astronomers use to organize the sky. Both the Big and Little Dippers are asterisms.
Object of the week for April 29 is the Little Dipper. Even though the Little Dipper is well known to most, it is not nearly as easy to find as most would think. Frequently people think that the star cluster M45 (Pleiades) is the Little Dipper. It does indeed look like a small spoon but it is never seen in the north.
