ALMA has captured a vast stream of gas feeding the young triple-star system GW Orionis, located about 1,300 light-years away. Stretching roughly 12,000 astronomical units (0.2 light-years), the streamer connects the surrounding molecular cloud with the system\u2019s unusual, misaligned planet-forming rings.<\/p>\n
The observations provide strong evidence that late infall of material from a star\u2019s natal cloud can transfer angular momentum to a protoplanetary disk and influence its structure and evolution. The study combines observations from all three ALMA arrays and offers new insights into the dynamic environments in which planets form.<\/p>\n
