Different methods of studying cosmic expansion yield slightly different results, including for the age of the universe. In a new study, astronomers from the Harvard-Smithsonian…
New results from the Dark Energy Survey (DES) reveal the most accurate measurement of dark matter structure in the universe, and support the view that…
A new study details the results from the largest-ever, three-dimensional map of distant galaxies. The map is one of the most precise measurements yet of…
Researchers are using a large sample of galaxy cluster to investigate dark energy, showing that dark energy has not changed over billions of years. Astronomers…
Astronomers hope that by studying the properties of galaxy clusters at different stages in the history of the Universe they can shed light on the…
The Dark Energy Spectroscopic Instrument has archived it second major milestone, approval of Critical Decision 2 (CD–2) authorizing the project’s scientific scope, schedule, and funding…
A team of physicists reproduced the low-density conditions of space to precisely measure dark energy, helping to reveal how strongly dark energy interacts with normal…
The Dark Energy Survey has discovered 17 dwarf galaxy candidates in the past six months, leaving scientists to believe that there could be many more…
Scientists have created the largest single high-definition map of dark matter, helping researchers understand the role that dark matter plays in galaxy formation. Scientists on…
Astronomers used data from NASA’s Galaxy Evolution Explorer to analyze several sites where dead stars once exploded, revealing that the Type Ia supernovae affiliated with…
Newly published research reveals that dark matter is being swallowed up by dark energy, offering novel insight into the nature of dark matter and dark…
The Dark Energy Survey has revealed a rare, ‘superluminous’ supernova that erupted in a galaxy 7.8 billion light years away. The first images taken by…
New maps from the Fermi-LAT Collaboration show that the galactic center produces more high-energy gamma rays than can be explained by known sources, suggesting that…
New theoretical research suggests that quintessence and phantom fields, two of the many theories that try to explain the nature of dark energy, are only…
Two new studies report that x-rays emanating from the hearts of nearby galaxies and galaxy clusters could be signs of particles of dark matter decaying…
Dartmouth researchers shed new light on dark energy and eliminate the possibility that our planet, solar system and galaxy are at the center of the…
After 10 years of planning, building, and testing, the Dark Energy Survey (DES) has officially begun. Tonight, as the sun sinks below the horizon, the…
