PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Colliding galaxies. Computer artwork of colliding galaxies seen from an alien planet. Collisions between galaxies are fairly common. The collision distorts the shape of both galaxies, often casting off streamers of stars. Despite the fact that the galaxies may pass through each other, collisions between actual stars are exceedingly rare. Also seen is an extrasolar gas giant planet (left). Gas giants are large planets that have a rocky or metallic core, but the majority of their mass is a mixture of gases.
