Sources of high-energy astrophysical neutrinos
Neutrinos (nearly massless particles that pass through matter almost untouched) arrive from space with energies from about 1e13 eV to about 2e17 eV. Only a few sources have been identified, and most of the flux has no known origin.
Why it matters
Neutrinos travel in straight lines from where cosmic rays collide with matter or light, so they point back to the accelerators.
