These particles are so ghostly that trillions of them pass through Earth each day without notice. So, how do we detect them?

Nothing can travel faster than the speed of light in a vacuum ... For water at room temperature, this angle is 41º. In a water Cherenkov detector, the Cherenkov radiation is detected, usually by ...

Deep beneath Japan's mountains lies a scientific marvel—the Super-Kamiokande—home to some of the purest water on our planet. This underground facility is not only notable for its breathtaking design ...

uses an array of 300 water tanks to detect Cherenkov radiation—the faint flashes of light that occur when particles move faster than the speed of light in water. This setup allows HAWC to ...

“These particles travel faster than the speed of light in air and as a result they emit a flash of eerie blue Cherenkov radiation — similar to a sonic boom created by an aircraft exceeding the ...

as well as Cherenkov radiation resulting from charged particles exceeding light speed in a medium. MACE will also enable research into black holes. It is expected to detect high-energy gamma rays ...
