		Professor Koshiba, together with Raymond Davis Jr., Professor Emeritus at the University of Pennsylvania, was recognized for his work in detecting neutrinos - subatomic particles that have traveled through space.
		In 1988, researchers continuing the work of Professor Koshiba determined that neutrinos have mass, a discovery of such import that the theories of subatomic physics had to be rewritten.

		and the Japanese Masatoshi Koshiba jointly, “for pioneering contributions to astrophysics, in particular for the detection of cosmic neutrinos”.
		The results first obtained by Davis were later confirmed in a second experiment led by Masatoshi Koshiba at the Japanese Kamiokande detector (the project had actually been conceived for the study of proton decay, but then it turned out extremely interesting results on both solar and atmospheric neutrinos).
		On February 23, 1987, a group led by Koshiba was also able to detect the neutrinos produced by a superno va explosion: an extremely rare phenomenon that has not since taken place again, so that to this day that supernova and the Sun remain the only proven neutrino sources in the Cosmos.

		Inspired by Davis's results, Masatoshi Koshiba converted his underground Kamiokande experiment from a proton decay detector to a neutrino spotter in 1986.
		Koshiba and his colleagues had placed photomultiplier tubes, which detect single photons, around 2,000 tons of water to see the Cherenkov light that would appear if a proton decayed.
		Davis and Koshiba made extraordinary contributions in part because "solar neutrino experiments have a sensitivity that is not accessible [with neutrinos] from the Earth," says Bahcall.
