The Dark Energy Survey (DES) is a scientific project aimed at understanding the mysterious force known as dark energy, which is believed to be responsible for the accelerated expansion of the universe. Conducted from 2013 to 2019, the survey utilized a powerful telescope located at the Cerro Tololo Inter-American Observatory in Chile to capture detailed images of the night sky. The DES focused on mapping the distribution of galaxies, galaxy clusters, and supernovae across a large area of the sky. By analyzing this data, researchers hoped to gain insights into the nature of dark energy and its impact on the universe's structure and evolution.
