Uno spettacolo galattico
La collisione, che ha iniziato più di 100 milioni di anni fa ed è ancora in corso, ha provocato la formazione di milioni di stelle in nubi di polveri e gas nelle galassie. Il più massiccio di queste stelle giovani hanno già accelerato attraverso la sua evoluzione in pochi milioni di anni ed esplose come supernove.

A Galactic Spectacle
The Antennae galaxies, located about 62 million light years from Earth, are shown in this composite image from NASA's Great Observatories--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. These features were produced by tidal forces generated in the collision.
The collision, 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.
