This photo provided by Sanford Lab shows the massive Large Underground Xenon (LUX) dark matter detector being installed in the Davis Cavern of the Sanford Lab in South Dakota. The tank measures 24 feet in diameter, is two stories high and will hold 71,600 gallons, weighing upwards of 300 tons of water, that will shield the LUX dark matter detector from outside interferences.
