Astronomers have known for two decades that the expansion of the universe is accelerating, but the physics of this expansion remains a mystery. Now, a…
For just the second time ever, astrophysicists have spotted a spectacular flash of ultraviolet (UV) light accompanying a white dwarf explosion. An extremely rare type…
The Dark Energy Spectroscopic Instrument, which will map millions of galaxies in 3D, reaches final milestone toward its startup. Even as the Dark Energy Spectroscopic…
A new paper has shown how large structures in the distribution of galaxies in the Universe provide the most precise tests of dark energy and…
Before COVID-19 hit U.S., project was on track to begin its 3D map of the universe this summer. The Dark Energy Spectroscopic Instrument (DESI), installed…
Study by the Universities of Bonn and Harvard raises doubts about basic assumption for the universe. No matter where we look, the same rules apply…
One of the biggest mysteries in science began with a dying star. It wasn’t any particular dying star so much as the idea of one….
New evidence shows that the key assumption made in the discovery of dark energy is in error. High precision age dating of supernova host galaxies…
The Dark Energy Survey (DES) program uses the patterns of cosmic structure as seen in the spatial distribution of hundreds of millions of galaxies to…
The fact that our Universe is expanding was discovered almost a hundred years ago, but how exactly this happens, scientists realized only in the 90s…
The Dark Energy Spectroscopic Instrument begins final testing, setting the stage for a 5-year survey that will analyze the light of 35 million galaxies. A…
Two University of Hawaii at Manoa researchers have identified and corrected a subtle error that was made when applying Einstein’s equations to model the growth…
A team of physicists and computer scientists at ETH Zurich has developed a new approach to the problem of dark matter and dark energy in…
[Editor’s Note: The Wide Field Infrared Survey Telescope (
An experiment to test a popular theory of dark energy has found no evidence of new forces, placing strong constraints on related theories. Dark energy…
A new study using data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton suggests that dark energy may have varied over cosmic time. This artist’s…
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…
