Antennae: A Galactic Spectacle

A pair of colliding galaxies about 62 million light years from Earth and about 61,000 light years across. In the constellation Corvus (crow), it is visible in the Southern Hemisphere and very low on the southern horizon in the Northern Hemisphere. The collision of the Antennae galaxies, which began more than 100 million years ago and is still occurring, has triggered the formation of millions of stars in clouds of dusts and gas in the galaxies. The most massive of these young stars have already sped through their evolution in a few million years and exploded as supernovas.
