Corvus is a constellation dating back to classical times, representing a crow sent by the god Apollo to collect a cup containing the water of life (and that cup is represented by the neighbouring constellation of Crater). Probably the most notable objects within Corvus are the Antennae Galaxies, a pair of galaxies some 45 million light years from the Milky Way, whose interactionn with one another to create tendrils of material spiralling into space.
