The IceCube project in Antarctica is designed to detect these particles in the previously unexplored PeV energy region and is based on the earlier AMANDA project also located near the South Pole.

The direct Urca process, described by George Gamow, is one the simplest interstellar processes which produce these particles, and it is currently unproven whether these particles are Majorana particles, serving as their own antiparticles. Work conducted at Super-Kamiokande provided evidence for flavor oscillation, which in turn proves that they have non-zero mass. For 10 points, name these extremely low-mass, uncharged leptons, which come in tau, mu, and electron varieties.
