Window on a Window to the Universe

An underwater camera mounted in the SNO+ (Sudbury Neutrino Observatory) neutrino detector captures a snapshot image when the 12-metre diameter acrylic sphere is 85% full. Viewed from below, ropes are seen crisscrossing the top of the sphere extending down (foreground), and each of the shiny cells that are visible is a 20-cm diameter super-sensitive light detector. The water-air interface inside and outside the acrylic spherical tank creates visual distortions as light refracts at the optical boundary. Once full, the upgraded detector turns on in Fall 2016, ten years after the original SNO detector completed its Nobel-prize winning studies.
