The Beijing-Arizona Sky Survey (BASS) team of National Astronomical Observatories of Chinese Academy of Sciences (NAOC) and their collaborators of the Dark Energy Spectroscopic Instrument…
The Dark Energy Survey has released a massive, public collection of astronomical data and calibrated images from six years of work. Containing data on nearly…
Three years after its initial test observations, the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is now training its full suite of instrumentation to reveal the…
Using Planck data from the cosmic microwave background radiation, an international team of researchers has observed a hint of new physics. The team developed a…
The Extreme-Horizon collaboration run by teams at the CEA, CNRS, Sorbonne Université and Université Paris-Saclay has produced a completely new simulation of the evolution of…
Dark energy is one of the greatest mysteries in science today. We know very little about it, other than it is invisible, it fills the…
UC Riverside-led team’s technique relied on determining the mass of galaxy clusters. A top goal in cosmology is to precisely measure the total amount of…
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…
