Antennae Galaxies. Hubble Space Telescope image of star birth caused by the interactions of the Antennae Galaxies (NGC 4038/4039). These two spiral galaxies are colliding in the constellation of Corvus at a distance of about 63 million light years from Earth. Their cores (orange, at centre left & upper right) are crossed by dark lanes of dust. Chaotic gas clouds lie between the cores. The creation of over 1000 bright, young star clusters (white/blue) has been triggered by the galaxies' collision. Image taken by Hubble's Wide Field Planetary Camera 2; the smallest visible features are 15 light-years across.
