Neutrinos are one of the most enigmatic particles in the standard model. The main reason is that they're so hard to detect. Despite the fact that 400 trillion of them created in the sun are passing through a person's body every second, they rarely interact with normal matter, making understanding anything about them difficult. To help solve their mysteries, a new neutrino detector in China recently started collecting data, and hopes to provide insight on between forty and sixty neutrinos a day for the next ten years.
