Hydra (constellation)

Hydra is a constellation that has parts in the northern sky and parts in the southern sky.  It is the biggest constellation.  It represents a water snake.  The astronomer named Ptolemy listed Hydra when he made a list of 48 constellations.  It is also one of the 88 modern constellations that were made by the International Astronomical Union.

Even though Hydra is a very big constellation, it only has one bright star.  This star is named Alphard.  Alphard means "the solitary one" in Arabic. Hydra actually has little to identify it exept for a cluster of stars at its head.
