DG Tauri B is a young stellar object located 450 light-years (140 parsecs) from Earth, near the T Tauri star DG Tauri,[3] within the Taurus constellation.[4] Observations of DG Tauri B were first made in October, and later December 1995 at the 6 element Owens Valley millimeter wave array.[5] Its most notable characteristics are its bipolar jets of molecular gas and dust emanating from either side of the object.[4][5] 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.[5]
