When you're building a massive telescope designed to detect subtle shapes in the light emitted by distant galaxies, you'd like to know that the shapes you are seeing are accurate and not the result of defects in your telescope's sensors. Fortunately sensors for the camera of the Large Synoptic Survey Telescope (LSST), expected to see "first light" from atop a mountain in Chile in 2020, just received very promising "vision" test results from physicists at the U.S. Department of Energy's Brookhaven National Laboratory.
