How did spiral galax ESO510-13 get bent out of shape?The disks of many spirals ar thin and flat, but not solid.Spiral disks are loose conglomerations ofbillions of stars and diffuse gas al gravitationallyorbiting a galaxy center.A flat diskis thought to be created by sticky collisionsof large gas clouds early in th galaxy's formation. Warped disks are not uncommon, though, and even our own Milky Way Galaxy is thought to havea small warp. The causes of spiral warps are still being investigated, but some warps are thought to result from interactions or even collisions between galaxies. ESO 510-13is about 150 million light years away and about 100,000 lightyears across.
