Neutrinos Neutrinos Neutrinos are tiny particles that penetrate all objects German physicist Wolfgang Pauli predicted the existence of neutrinos in 1933 and his theory was proved 26 years later.
Neutrinos are particles with almost no mass and no electric charge.
Neutrinos barely interact with other particles and because they penetrate all other objects, they can travel from the furthest reaches of space, or the center of the Sun to Earth. This ability also makes it very difficult to observe neutrinos. They can be detected by a reverse beta reaction which rises from the collision between neutrinos and the core of such elements as chlorine, hydrogen or gallium. The project that started studies in astronomical neutrinos Neutrinos released from the massive explosion of the supernova 1987A in the Large Magellanic Clouds were found by Kamiokande, a massive tank filled with pure water that acts as a neutrino detector and is located in the Kamioka Mine in Gifu Prefecture. This discovery paved the way for studies in astronomical neutrinos.
