NEW METHOD OF MAPPING THE UNIVERSE USING QUASARS -BOSS. The biggest 3-D map of the distant universe ever made, using light from 14,000 quasars – supermassive black holes at the centers of galaxies billions of light years away – has been constructed by scientists with the third Sloan Digital Sky Survey (SDSS-III). See the Phyorg …
