  • Gas-phase interstellar chemistry is thought to be dominated by ion–molecule reactions. Neutral molecular species abound in the dense interstellar clouds, but only seven molecular ions have been detected. Hydronium (H3O+) is predicted in all ion–molecule reactions1–3 to be an abundant molecular ion, forming OH and H2O by dissociative electron recombination reactions. Here we report the detection, towards the Orion-KL nebula, of a weak emission spectral line coincident in frequency with the P(2,l… CONTINUE READING
