Follow @COSISnews on Twitter New Scientist: Giant Antarctic balloon sees surprise cosmic rays16.10.2010, Age: 3756 days A neutrino telescope that makes use of thick Antarctic ice and a giant balloon is unexpectedly detecting mysterious, ultra-high-energy cosmic rays. The Antarctic Impulsive Transient Antenna (ANITA) is a radio wave detector mounted on a giant balloon at an altitude of 38 kilometres. It is designed to detect the radio waves produced when a high-energy cosmic neutrino smashes into the thick ice below. But although ANITA has yet to capture this signature, it has found another kind of particle: ultra-high-energy cosmic rays. These are protons and other charged nuclei that zoom in from space with mysteriously high energies.
