UNIVERSITY PARK, Pa., April 20 -- Pennsylvania State University issued the following news release:

UNIVERSITY PARK, Pa. - Buried within the Antarctic ice are more than 5,000 light sensors that work together to detect some of the highest energy particles in the universe. These tiny particles, called neutrinos, provide insight into the extreme cosmic events that created them as well as phenomena that challenge traditional physics.

Located at the U.S. National Science Foundation's Amundsen-Scott South Pole Station, the IceCube Neutrino Observatory takes advantage of the pristine ice to detect the tiny, nearly massless neutrinos. Then, the international IceCube collaboration, with more than 450 scientists from around the world, reconstructs t...
