The Baryon Oscillation Spectroscopic Survey (BOSS), the largest component of the third Sloan Digital Sky Survey (SDSS-III), pioneered the use of quasars to map density variations in intergalactic gas at high redshifts, tracing the structure of the young universe.
Scientists using BOSS, the Baryon Oscillation Spectroscopic Survey, have used a new mapping technique to probe the period before dark energy began to speed up the expansion of the universe.
The biggest-ever 3D map of the universe has been released, including more than 500,000 galaxies and 100,000 stars.
A British teenager has launched a new site called We Know What You're Doing, exposing some of the suicidally stupid messages people still persist on posting on Facebook.
After two years' work, the Sloan Digital Sky Survey (SDSS-III) has measureed the precise distances of over a quarter of a million galaxies.
Scientists have created the biggest ever 3D map of the distant universe, using the light from 14,000 supermassive black holes, or quasars, at the centers of galaxies billions of light years away.
