Herschel image of CW Leonis
This colour-composite image of CW Leonis, also known as IRC +10216, was obtained with the SPIRE and PACS instruments on the Herschel Space Observatory. It combines observations at wavelengths of 160 µm (blue; PACS), 250 µm (green; SPIRE) and 350 µm (red; SPIRE).
A bow shock, created by the interaction of the stellar wind emitted by the star and the interstellar medium, can be seen to the left of the star.
The image is 15x15 arcminutes.
