In today’s The Conversation article “Shooting the moon: the search for ultra high energy neutrinos” CSIRO Fellow Ron Ekers and Helen Sim describes not only the “Oh-my-God” particle, a particle from space – probably the nucleus of an iron atom with the energy of a well-bowled cricket ball, but also neutrinos and using the Moon as a neutrino detector. Using the novel 13-beam receiver system on the 64-m Parkes Telescope, Ekers et al. searched for flashes of radio wave lasting just a nanosecond, generated by neutrinos interacting with rocks under the moon’s surface (known as the Askaryan effect).
