The Dark Energy Survey: Map of 226M Galaxies Provides an Unprecedented Look at the Evolution of the Universe

The Dark Energy Survey collaboration, which involves more than 400 scientists from 25 institutions, has completed the largest-ever map of the universe. Detailing the distribution and shapes of galaxies extending more than 7 billion light-years, the data provide researchers with a record of how the universe evolved over time. The Dark Energy Survey tackles big questions about our universe: What is it made of? How is matter distributed? How has the universe evolved? And what roles do dark matter and dark energy play? To address these puzzles, the experiment uses a powerful 570-megapixel camera to photograph galaxies close to home and billions of light years away. The analysis of the first three years of data resulted in the largest maps ever made showing the distribution and shapes of galaxies in our universe, and provided a fantastic test for scientist’s best predictions. https://www.technology.org/2021/05/28/map-of-226m-galaxies-provides-unprecedented-look-at-the-evolution-of-the-universe/ ........................................................................... #space #science #nature #education #news
