Cherenkov Radiation, a phenomenon that occurs when particles travel faster than the speed of light in a given medium. It produces this gorgeous blue color, and is perfectly safe to observe. :
Emily Conover on X: "This weekend I got to tour @UofMaryland's nuclear reactor with @DCSWA and when I peered down into the pool and saw the blue glow of Cherenkov radiation, I
