Trillion-mile gas streamer may explain tilt of triple-star system's outer planet-forming ring

A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has captured a massive stream of gas—one trillion miles, or 0.2 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. The findings are published in The Astronomical Journal.
