Dark Energy Survey News

The Dark Energy Survey (DES) is an astronomical survey designed to explore the dynamics of the expanding universe and the growth of large-scale structure, providing insights into the mysterious phenomena of dark energy. Conducted using the Blanco 4-meter telescope at the Cerro Tololo Inter-American Observatory in Chile, DES began in August 2013 and concluded its observations in January 2019. The survey utilized a 570-megapixel digital camera (DECam) to capture deep images of the sky in five optical filters over approximately one-eighth of the sky. The primary goals of DES include producing detailed maps of the distribution of galaxies to study the structure of the universe over time, testing theories and models of dark energy, and improving our understanding of the evolution of the cosmos. The data from DES has been instrumental in creating the most precise maps to date of the distribution of galaxies and the large-scale structure they form, shedding light on the dark components of the universe that drive its expansion.
