Neutrinos from Different Directions (IMAGE) University of Wisconsin-Madison Caption In this study, researchers measured the flux of muon neutrinos as a function of their energy and their incoming direction. Neutrinos with higher energies and with incoming directions closer to the North Pole are more likely to interact with matter on their way through Earth.
