A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), of which the U.S. National Science Foundation National Radio Astronomy Observatory is a partner, has captured a massive stream of gas--one trillion miles, or .2 light years long--feeding the young triple-star system GW Orionis. These new observations provide the clearest evidence yet for how such "streamers" can tilt and twist the disks where planets are born.A Trillion Mile Cosmic Stream of Gas Feeds GW Orionis
