Hundreds of scientists from the Sloan Digital Sky Survey III (SDSS-III) collaborated to make the largest-ever, three-dimensional map of distant galaxies. The astronomers then used this map to make one of the most precise measurements yet of the dark energy currently driving the accelerated expansion of the universe.
The Big Bang Theory with its early period of exponential growth known as inflation is the prevailing scientific model for our universe, in which the entirety of space and time ballooned out from a very hot, very dense point into a homogeneous and ever-expanding vastness. This theory accounts for many of the physical phenomena we observe, but what if that’s not all there was to it?
The U.S. Department of Energy has approved the start of construction for a 3.2-gigapixel digital camera — the world’s largest — at the heart of the Large Synoptic Survey Telescope (LSST). Assembled at the SLAC National Accelerator Laboratory, the camera will be the eye of LSST, revealing unprecedented details of the universe and helping unravel some of its greatest mysteries.
