天文学家终于观测到驱动原恒星喷流的扭绞磁场

天文学家长期以来推测原恒星喷流受扭绞磁场驱动，但一直未能直接观测到。借助阿塔卡马大型毫米/亚毫米波阵（ALMA），研究人员现已在原双星周围探测到了此类磁场结构。

For decades, scientists have theorized that young protostar jets are shaped and driven by complex, twisted magnetic fields. But they couldn't detect them. Now, thanks to ALMA, they've found them around a young binary protostar.
