Hydra, the Water Snake, is the largest constellation of the celestial sphere. Its length spans more than a quarter around the sky (about 7 hours in alpha). Hydra can be seen best in spring time (northern hemisphere). However, the stars shine just faintly and from Europe and North America the constellation creeps close to the southern horizon.
