Left: this image from the Multi Unit Spectroscopic Explorer (MUSE) on ESO’s Very Large Telescope shows the parent cloud LHA 120-N 180B in which the HH 1177 system was first observed. Center: this image shows the jets that accompany HH 1177; the top part of the jet is aimed slightly towards us and thus blueshifted; the bottom one is receding from us and thus redshifted.
