In the constellation of Pisces, 100 million light-years from Earth, two galaxies are smashing together in a dramatic demonstration of our far future: when the Milky Way collides with the Andromeda Galaxy. This image of NGC 520 was taken with the Gemini North Telescope on the evening of July 13-14, 2005. It's possible to see dark dust lanes and a long trail of stars thrown out by the cosmic collision.
