 Mythology of Corvus

This small constellation south of Virgo represents a crow perched on the coils of Hydra, the water-snake. In Greek mythology, the crow was sent by Apollo to fetch water in a cup (represented by the adjoining constellation of Crater), but greedily stopped to eat figs instead. On its return, the crow blamed the water-snake for delaying it. But Apollo, who was not fooled by the lie, condemned the crow to a life of thirst, just out of reach of the cup in the heavens.

NGC 4038 and 4039 (The Antennae)

antennae

A famous pair of interacting galaxies. They are small and of 11th magnitude, so a telescope of moderate to large aperture is needed to see them. Long-exposure photographs show two streamers of stars and gas that extend from the colliding galaxies like the feelers of an insect, giving rise to the popular name.
