In 1998 scientists measuring the expansion of the Universe made a startling discovery: the Universe is accelerating. Previously, researchers believed that the expansion of the Universe would eventually slow under the influence of gravity.

The Sloan Digital Sky Survey (SDSS-III) announced the most accurate measurements yet of the distances to galaxies in the faraway universe, giving an unprecedented look at the time when the universe first began to expand at an ever-increasing rate.

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).

Several ways have been proposed to examine dark energy, in hopes of finding out just what it is. One of them, “supernovae” for short, certainly works: it’s how dark energy was discovered in the first place.
