Cosmic Swirly Straws Feed Galaxy




HD - NASA's Jet Propulsion Laboratory show

Summary: Created with the help of supercomputers, this simulation shows the formation of a massive galaxy during the first 2 billion years of the universe. Hydrogen gas is gray, young stars appear blue, and older stars are red. The simulation reveals that gas flows into galaxies along filaments akin to cosmic bendy, or swirly, straws.
