Hydra, also known as the water snake, is the largest constellation in the sky. It covers 3% of the celestial sphere. Mythology depicts hydra as a 9-headed monster with one immortal head. If you cut off one hydra head, two more would grow back in its place.  In the sky, hydra is only shown with one head - perhaps this is the immortal one?
