Abstract A number of very strong radio sources in the sky have been identified visually as two galaxies in collision. One of these, Cygnus A, emits radio energy at the enormous rate of 10~~ ergs/sec. A factor not mentioned in previous discussions on energy production in colliding galaxies is the surprising observation that very large energy production rates may be obtained from deuterium thermonuclear reactions in the extremely rare hot gas that is formed by the collision. It is shown that for one deuteron in 20 nuclei in the gas of the galaxies, the thermonuclear energy output of Cygnus A would be roughly equal to the radio noise output observed. The possibility of detecting d#d reactions in a strong radio source by looking for the high-energy gamma rays from an earth satellite will be discussed.
