Noble gas molecules have not hitherto been detected in space. From spectra obtained with the Herschel Space Observatory, we report the detection of emission in the 617.5- and 1234.6-gigahertz J = 1-0 and 2-1 rotational lines of ³⁶ArH⁺ at several positions in the Crab Nebula, a supernova remnant known to contain both molecular…
