Follow the coils of Hydra this spring to see some of the most strikingly colorful stars in the sky.
Out of the 88 constellations, more than half represent animals or hybrids of animals. Some of these are mythological creatures that never existed, such as the unicorn, the sea goat and the two centaurs (Centaurus and Sagittarius). A few of them are in the reptile family. One of these cold-blooded creatures, which has appeared in this column on several other occasions, slithers across the southern sky on these midspring evenings. It's the largest constellation in the sky: Hydra, the water snake.
