Today's Astronomy Picture of the Day is a Hubble Space Telescope and ground-based (Subaru Telescope) combined image of NGC 4038 and NGC 4039, the "Antennae" in the constellation of Corvus. Two galaxies are colliding in slow motion! The "Antennae" are also part of Halton Arp's Atlas of Peculiar Galaxies, a interesting astronomical artifact.
