Description

This huge southern constellation was one of the 48 constellations (there are now 88) described by the great ancient astronomer Ptolemy in his Almagest. It is the ship which Argus built for Jason and his crew, the Argonauts, to carry them on their quest for the Golden Fleece. After their many adventures, Athena raised their ship to the sky.

In the 18th century the French astronomer Lacaille dismantled it into three smaller constellations, Carina the Keel, Puppis the Stern or Poop, and Vela the Sail, with small Pyxis the Compass located nearby. To view Argo Navis you'll need to sail to Australia or South America; only Puppis becomes visible to observers in the US. See these constellation pages for descriptions of special stars and objects in this area.
