Located about 62 million light years from Earth, the Antennae Galaxies are shown in this composite image from NASA's Great Observatories. This image was taken by the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red).
The Antennae galaxies take their name from the long antenna-like "arms," seen in wide-angle views of the system and were created when tidal forces generated a collision. The collision began more than 100 million years ago and is still occurring. As a result, millions of stars in clouds of dusts and gas were formed 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.
