Far-IR (FIR) images of the archetype carbon star CW Leo (IRC +10216) by the Herschel Space Observatory (Pilbratt et al. 2010) reveal an extended structure at about 11' from the star which correlates with the UV structure seen by the GALaxy Evolution EXplorer Space Observatory (GALEX) (Sahai & Chronopoulos 2010). The UV emission is believed to be due to the shocked asymptotic giant branch (AGB) wind with the interstellar medium (ISM) (Sahai & Chronopoulos). We present our main results from the Herschel data on the wind-ISM interaction.
