}}{{Starbox end}}DG Tauri B, a faint companion of the T Tauri star DG Tauri,[ is a young stellar object located 450 light-years (140 parsecs) from Earth, within the Taurus constellation.[7] Observations of DG Tauri B were first made in October, and later December 1995 at the 6 element Owens Valley millimeter wave array.[8] Its most notable characteristics are its bipolar jets of molecular gas and dust emanating from either side of the object.[7][8] Red-shifted carbon monoxide emissions extend out 6,000 au to the northwest of the object from the undetermined source, and are symmetrically distributed about the jet, while blue-shifted CO emissions are confined to a region with a roughly 500 au radius.[8]] References 1. ^1 2 {{cite DR2}}
