About 25 years ago, astrophysicists noticed something very interesting about the Universe. The fact that it was in a state of expansion had been known…
Dark energy, the mysterious force that causes the universe to accelerate, may have been responsible for unexpected results from the XENON1T experiment, deep below Italy’s…
Scientists estimate that dark matter and dark energy together are some 95% of the gravitational material in the universe while the remaining 5% is baryonic…
Dark Energy Survey Releases Most Precise Look at the Universe’s Evolution First three years of survey data uses observations of 226 million galaxies over ⅛…
Successful Start of Dark Energy Spectroscopic Instrument (DESI) Follows Record-Setting Trial Run A five-year quest to map the universe and unravel the mysteries of dark…
Physicists’ new proposal that a new type of extra dark energy is involved is highlighted in scientific journal. The universe was created by a giant…
The universe we see is only the very tip of the vast cosmic iceberg. The hundreds of billions of galaxies it contains, each of them…
For the first time, DES scientists can combine measurements of the distribution of matter, galaxies, and galaxy clusters to advance our understanding of dark energy….
The extended Baryon Oscillation Spectroscopic Survey (eBOSS) collaboration has released its latest scientific results. These results include two studies on dark energy led by Prof….
Researchers the world over have long believed that 70 percent of the universe is composed of dark energy, a substance that makes it possible for…
