About
After six years of observations, the Dark Energy Survey has delivered its most precise analysis of cosmic expansion, based on hundreds of millions of galaxies.
Using weak gravitational lensing and galaxy clustering, scientists refined measurements of dark energy and confirmed much of the standard cosmological model—while revealing a persistent tension in how matter clusters across time.
These results deepen our understanding of the accelerating universe and set the stage for the next generation of cosmic observatories.
