The neutrino detector Super-Kamiokande in Japan contains 50,000 tons of ultrapure water surrounded by detectors used to pinpoint collisions of neutronos with the water molecules.

The Sudbury Neutrino Observatory in Canada has used neutrinos from 8B decay in the Sun to observe one neutrino reaction sensitive only to solar electron neutrinos and others sensitive to all active neutrino flavors. It found clear evidence for neutrino flavor change that also requires that neutrinos have non-zero mass. This evidence requires modification of the Standard Model for elementary particles, and confirms solar model calculations with great accuracy. The 2015 Nobel Prize in Physics and the 2016 Breakthrough Prize in Fundamental Physics were awarded for these measurements. — Perimeter Institute
In his live public lecture tonight at 7 p.m. EDT, Nobel Laureate Art McDonald will delve into the science behind detecting the most ghostly known particles in the universe. By creating vast underground caverns filled with ultrapure water, neutrino detectors have been able to explore some of the most fundamental mysteries of physics, from the core of our sun to the furthest-most reaches of the universe.
Watch the live feed below at 7 p.m. ET; you can also get involved and ask questions via the Perimeter Facebook pageor via Twitterduring the event using the hashtag #piLIVE. Don’t miss it!
