| Astronomers observe galactic 'blow out' Posted: 04 Dec 2014 06:11 AM PST For the first time, an international team of astronomers has revealed the dramatic 'blow out' phase of galactic evolution. The astronomers have discovered dense gas being blasted out of a compact galaxy (called SDSS J0905+57) at speeds of up to two million miles per hour. The gas is being driven to distances of tens of thousands of light years by the intense pressure exerted on it by the radiation of stars that are forming rapidly at the galaxy's center. This is having a major impact on the evolution of the galaxy. |
