SUMMARY

The Dark Energy Survey (DES) is an international, collaborative effort to map hundreds of millions of galaxies, detect thousands of supernovae, and find patterns of cosmic structure to reveal the nature of the mysterious dark energy that is responsible for the accelerating expansion of our Universe. During the first part of the project, an extremely sensitive 570-Megapixel digital camera was built and mounted on the Blanco 4-meter telescope in Chile. 2013-2018, observations were carried out and huge amounts of data collected to create a map of the universe as seen from the southern hemisphere of our planet.

The Blanco Telescope is located at the Cerro Tololo Inter-American Observatory (CTIO) in the Chilean Andes. The 4-meter telescope was constructed in the 1970’s and upgraded for the installation of DECam, the camera used for the Dark Energy Survey. Image: H. Sathiapal

The Camera mounted on the telescope for the Dark Energy Survey had an imager with 74 CCD components, similar to but much more sensitive than those in ordinary digital cameras. Credit: The Dark Energy Survey
