Lawrence Berkeley National Laboratory: The Baryon Oscillation Spectroscopic Survey (BOSS), the largest component of the third Sloan Digital Sky Survey, has measured the clustering of nearly 1.3 million galaxies spectroscopically to determine the "standard ruler" of the universe's large-scale structure to within one percent. This is the most precise such measurement ever made and is likely to establish the standard for years to come.
