Hydra, the Water Snake, is at its best visibility tonight. The largest constellation in the entire sky, it’s head rises up beneath Cancer the Crab, its long, serpentine body stretches below Leo, around Crater the Cup and Corvus the Crow and its tail lies beneath Virgo, the Virgin.
It’s not an especially bright constellation and observers in the southern hemisphere will get the best view as it appears almost overhead. Meanwhile, observers in the northern hemisphere may be able to glimpse the snake slithering across the southern horizon.
