ALMA reveals protostellar jets and outflows in the Milky Way’s outer region [credit: Ikeda et al. (Niigata univ.), background: R. Hurt/NASA/JPL-Caltech/ESO]

Caption

Protostellar outflows and jets discovered in the outer Galaxy. The left panel shows CO line emission images obtained with ALMA observations. The red and blue contours represent high-velocity jet gas moving away from and toward us, respectively. The grayscale background indicates the distribution of lower-velocity outflow gas. The green star indicates the positions of the protostar. The yellow and green squares indicate the regions observed with ALMA in this study.
