Each image was taken through a different colour filter. From left to right, the images show how Betelgeuse appears in red (a wavelength of 700 nanometres), very near-infrared (905 nm), and near-infrared (1290 nm) light. To show this, we have coloured the images different shades of orange and red. 700 nm . ...

Marc White . ... Turbulent entrainment processes may play an important role in the outflows from young stellar objects at all stages of their evolution. In particular, lateral entrainment of ambient material by high-velocity, well-collimated protostellar jets may be the cause of the multiple emission-line velocity components observed in the microjet-scale outflows driven by classical T Tauri stars. ...
