Wikipedia
Neutrino astronomy is the branch of astronomy that observes astronomical objects with neutrino detectors in special observatories. Neutrinos are created as a result of certain types of radioactive decay, or nuclear reactions such as those that take place in the Sun, in nuclear reactors, or when cosmic rays hit atoms. Due to their weak interactions with matter, neutrinos offer a unique opportunity to observe processes that are inaccessible to optical telescopes.
The field of neutrino astronomy is still very much in its infancy – the only confirmed extraterrestrial sources so far are the Sun and supernova SN1987A.
Usage examples of "neutrino astronomy".
This was hailed by a number of scientists as the birth of neutrino astronomy, but I think that is wrong.
As soon as neutrinos from the Sun were detected, that was the beginning of neutrino astronomy.
And even the Sun represented only the beginning of observational neutrino astronomy.
New chapters opened up in the physics of colloids, in the physics of strong interactions, in neutrino astronomy, in nucleonics, biology, and, above all, the new knowledge of the Universe -- this represents but the first interest that has accrued to us from the informational principal, which, according to the experts, promises huge profits to come.
