Description: 

Looking like a chaste inverted checkmark on the mountaintop at Kitt Peak, Ariz., the world's largest solar telescope has a design almost as dramatic as the work that is being done there. Only a third of the telescope's 500-foot long shaft is above ground. The heliostat, or mobile mirror at the top of the shaft, follows the sun all day, reflecting sunlight down the shaft to two other mirrors before the image is projected in the observation room where by means of spectrographs astronomers can study the sun's composition. Mounts for all three mirrors were built by Westinghouse at Sunnyvale, Calif. The solar telescope is part of the National Science Foundation-financed Kitt Peak Observatory.
