The Cosmic Whale and Its Galactic Neighbors | Space Wallpaper
About this Image
A spiral galaxy scarcely 25 million light-years from Earth, The Whale Galaxy is similar in size to the Milky Way. Also known as NGC 4631, the galaxy has a brilliantly glowing elliptical sidekick as well as some other recently discovered neighbors that are dwarf galaxies. The galaxy is also surrounded by tidal star streams, fragments of a dwarf galaxy damaged by the gravitational effects of the Whale. [See more photos of galaxies across the universe.]
