The Dark Energy Spectroscopic Instrument seeks to further our cosmic understanding by creating the largest 3-D map of galaxies to date. Below is a press release issued by Lawrence Berkeley National Laboratory announcing first light for the optical lenses of this extraordinary instrument. The U.S. Department of Energy’s Fermi National Accelerator Laboratory is a key player in… More »

Also announces discovery of eleven stellar streams, evidence of small galaxies being eaten by the Milky Way At a special session held during the American Astronomical Society meeting in Washington, D.C., scientists on the Dark Energy Survey (DES) announced today the public release of their first three years of data.

New result rivals precision of cosmic microwave background measurements, supports view that dark matter and dark energy make up most of the cosmos   Imagine planting a single seed and, with great precision, being able to predict the exact height of the tree that grows from it. Now imagine traveling to the future and snapping… More »

Analysis will help scientists understand the role that dark matter plays in galaxy formation Scientists on the Dark Energy Survey have released the first in a series of dark matter maps of the cosmos. These maps, created with one of the world’s most powerful digital cameras, are the largest contiguous maps created at this level of detail… More »

Eight billion years ago, rays of light from distant galaxies began their long journey to Earth. That ancient starlight has now found its way to a mountaintop in Chile, where the newly constructed Dark Energy Camera, the most powerful sky-mapping machine ever created, has captured and recorded it for the first time. That light may… More »
