Artist's impression of the massive protobinary IRAS 16547-4247. A small gas disk surrounds each protostar, and they are embedded in the larger disk. Both protostars eject molecular gas outflows, while one emanates a collimated jet that collides with the surrounding gas and creates bright spots along the stream. Credit: ALMA (ESO/NAOJ/NRAO)
