The eight March constellations include many notable groups the most famous of which is Cancer, the crab. Cancer is home to two Messier objects, both open star clusters. The remainders of objects worth noting are found in the constellation Puppis. Puppis contains three Messier open star clusters. Most of the remaining groups were once part of a larger constellation called Argo Navis, which was the ship sailed by Jason and the Argonauts as they searched for the golden fleece. This large constellation was eventually split into four parts and the resulting groups are named after parts of the ship. Click on any constellation below for more information.
