Nuclear fusion is the only process reasonably capable of powering the sun, and one product of this fusion is invisible particles called 'neutrinos'. But why don't we observe as many solar neutrinos as theory would predict? ... Solar neutrino problems...

Electron neutrinos are produced in the Sun as a product of nuclear fusion. By far the largest fraction of neutrinos passing through the Earth are Solar neutrinos. The main contribution comes from the ...

Where have all the neutrinos gone? Solar models based on the latest physics tell us one thing but observations tell us something else. ... For more than twenty years, the Homestake Solar Neutrino Experiment in the Homestake Gold Mine in South Dakota has been attempting to measure neutrino fluxes from space; in particular,

Since energy is conserved, the extra energy is released as energy of motion of the nuclei in the solar gas and the production of lots of photons and, finally, the energy of the neutrinos. That is the gas gets hotter and has lots of photons. ... There are actually three kinds of neutrinos: the electron neutrino,

This is the origin of the long-standing "solar neutrino problem." The possibility that the missing electron neutrinos may have transformed into another type (undetectable to this experiment) is soon suggested, but unreliability of the solar model on which the expected neutrino rates are based is initially considered a...

But why? Above, scientists check the equipment surrounding a huge tank of extremely pure water from the Super-Kamiokande experiment in Japan, designed to detect colliding neutrinos. Large detectors are needed because the neutrino is an elementary particle that goes right through practically everything.

Still, to the long-standing consternation of astrophysicists, the observed flux of solar neutrinos is less than expected. In a new twist to this solar neutrino saga, an analysis of data from the GALLEX / GNO neutrino detector finds a solar neutrino flux that varies over about 27 days ...
