IceCube detects ghost particles with 10 billion times the energy of solar neutrinos

An enormous number of invisible particles are constantly traveling through Earth, passing through our bodies and continuing into space as though almost nothing stands in their way. Known as neutrinos, these mysterious particles are among the most difficult objects in the universe to detect. Yet scientists are finding ways to capture evidence of their passage, opening new opportunities to investigate the cosmos and its most extreme environments.
