One such particle, the neutrino could help scientists formulate the correct theory of the Sun. Unfortunately, all attempts till date to measure the number of neutrinos coming to us from the Sun have produced only one half the expected number from theoretical models of the Sun. Now the Sudbury Neutrino Observatory (sno) has found a solution to this so called
