In the 1960s, physicist Ray Davis, working deep underground in the Homestake gold mine in South Dakota, found that the flux of solar neutrinos hitting Earth was a third of that predicted by calculations of the nuclear reactions in the Sun by theorist John Bahcall. (scientificamerican.com)
Physicists finally solved that so - called solar neutrino problem last year, revealing that during their journey from the sun to Earth, some of the neutrinos change from one «flavor» to another. (scientificamerican.com)
Douglas Morrison of CERN, the European laboratory for particle physics, says the latest models of the way in which the Sun works predict solar neutrino fluxes which are almost consistent with the latest observations. (newscientist.com)
