Borexino, the Sun neutrino hunter
An international team of more than 100 researchers has used the huge Borexino detector to detect low-energy solar neutrinos for the first time. These results confirm recent 'theories about the nature of neutrinos and the inner workings of the sun and other stars.' In particular, it's now almost certain that neutrinos oscillate between three types, namely electron, muon and tau neutrinos. The Borexino detector used for these discoveries is located near L'Aquila, Italy. It is a 18-meter-diameter dome shielded by 2,400 tonnes of purified water and lying more than a kilometer underground to block interferences with cosmic rays. Impressive...
