The Dark Energy Survey publishes the most accurate measurement of the structure of dark matter in the universe. The new result competes in precision with measurements of microwave background radiation and confirms that dark matter and dark energy make up most of the cosmos. Researchers from CIEMAT, the Institut de Ciències de l'Espai (IEEC-CSIC), the Institute of Physics of Altes Energies (IFAE) and the Institute of Theoretical Physics (UAM-CSIC) participate in the result.

"With these fantastic measures, DES is beginning to show the enormous capacity it has to produce results that represent a significant advance in our understanding of the universe." The next few years may bring us surprises about the dark side of the universe, "said Eusebio Sánchez, The researcher responsible for the project at CIEMAT.

The main DES device is the 570-megapixel Dark Energy Camera, which is one of the most powerful astronomical cameras in existence today, capable of capturing digital images of galaxies eight billion light years from Earth. The camera was built and tested at Fermilab, the main laboratory of the Dark Energy Survey, and the Spanish collaboration group contributed decisively to its construction, as it was responsible for the design, manufacture and verification of the complete electronic system as well as the Guided tour of the Telescope. DES researchers use the camera for five years to study an eighth of the sky in unprecedented detail. The fifth year of observation will begin in mid-August.
