Every moment,trillions of neutrinos travel through your body unnoticed. Neutrinos are among the most abundant particles in the universe, but they are difficult to study because they very rarely interact with matter. To find traces of these elusive particles, or researchers from Caltech have collaborated with 39 other institutions to build a 14000-ton detector the size of two basketball courts called NuMI Off-Axis Electron Neutrino Appearance,or NOvA. The experiment, located in northern Minnesota, and began full operation in November 2014 and published its first results in Physical Review Letters this month.
