The first detection of gas-phase methanol in a protoplanetary disk (TW Hya) is presented. In addition to being one of the largest molecules detected in disks to date, methanol is also the first disk organic molecule with an unambiguous ice chemistry origin. The stacked methanol emission, as observed with ALMA, is spectrally resolved and detected across six velocity channels ($>3 \sigma$), reaching a peak signal-to-noise of $5.5\sigma$, with the kinematic pattern expected for TW~Hya. Using an… Expand
