Scientists in the Dark Energy Survey released results that have been five years in the making. Researchers used the world’s most complete census of dwarf galaxies around our Milky Way galaxy to probe the nature of dark matter, an invisible form of matter that dominates the universe. These new measurements provide information about what dark matter… More »

Over the past five years, the Dark Energy Survey, a DOE-funded project led by Fermilab, has revolutionized our view of small satellite galaxies. DES discovered a large number of tiny galaxies close to the Milky Way’s largest satellites, the Magellanic Clouds, suggesting that multiple galaxies may have been captured by the Milky Way at the… More »

The Department of Energy has awarded Fermilab and University of Chicago scientist Josh Frieman $1 million over three years as part of the inaugural Office of Science Distinguished Scientist Fellowship program. Office of Science distinguished scientist fellows were chosen from nominations submitted by nine U.S. national laboratories. Frieman is one of only five scientists selected,… More »

Why is our universe accelerating in its expansion? If Einstein’s theory of general relativity is correct, then the dark energy that drives this expansion accounts for nearly 70% of the total energy in the universe. However, precise measurements of the history of this expansion may reveal that new dynamic forces are in play. The Dark… 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. This first major release of… More »

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 »

New dwarf galaxy candidates could mean our sky is more crowded than we thought Scientists on the Dark Energy Survey, using one of the world’s most powerful digital cameras, have discovered eight more faint celestial objects hovering near our Milky Way galaxy. Signs indicate that they, like the objects found by the same team earlier this year, are… 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 »
