Seeking The Ghost Particle


The Super-Kamiokande neutrino observatory

The Super-Kamiokande neutrino observatory seen above, is located in a zinc mine 3,300 feet underground, near the city of Hida, Japan. The walls of the tank are instrumented with 13,000 light detectors, and in this photo you can see workers rowing around the interior as it fills with 50,000 tons of water. Neutrinos are subatomic particle that are notoriously hard to detect because they have no electric charge and they pass right through almost all ordinary matter. In fact, 100 trillion neutrinos apparently flow through our bodies every second. The Super-K observatory pictured here is just one detector that scientists are building to study these “ghost particles” as they’re known…
