IRC+10216 (CW Leo) is a carbon star surrounded by an expanding circumstellar envelope which is rich in molecules. Recently, Betz et al.1 reported the detection of rotation-vibration transitions of NH3 (ν2 band) in absorption against the infrared continuum of circumstellar dust. We now report the detection of the (1,1) and possibly the (2,2) inversion transitions of (para) NH3, the first radio detection of ammonia in a star. This information can be used to determine the thermal structure of the envelope of IRC+10216.
