The energy of ultra-high energy (UHE) cosmic rays that strike the Earth’s atmosphere make the energy produced from particle collisions by the Large Hadron Collider look puny. A team based in South Australia is now developing the techniques and technology to find out where such energetic particles could possibly originate. They ultimately hope to use the proposed SKA telescope to conduct their search.

“We think some cosmic rays are produced in the remnants of supernovae—exploding stars—but where the most energetic ones come from, that’s a mystery,” says Justin Bray, a PhD student hunting for their source as part of the LUNASKA (Lunar Ultra-high-energy Neutrino Astrophysics using SKA) project led by Ray Protheroe at the University of Adelaide and Ron Ekers at CSIRO.
