IceCube detects ghost particles with energy 10 billion times solar neutrinos

IceCube has detected neutrinos—often called “ghost particles”—with energies about ten billion times greater than those produced by the Sun. Using its massive detector embedded in Antarctic ice, scientists observed these extremely energetic particles arriving from distant cosmic sources. Researchers note that such neutrinos may provide clues about the Big Bang, extreme cosmic events and other fundamental mysteries.
