The Dark Energy Camera mounted on the 4-meter Blanco telescope at the Cerro Tololo Inter-American Observatory in Chile. The final day of data-taking for the Dark Energy Survey is Jan. 9.

After scanning in depth about a quarter of the southern skies for six years and cataloguing hundreds of millions of distant galaxies, the Dark Energy Survey will finish taking data on Jan. 9. DES scientists recorded data from more than 300 million distant galaxies. More than 400 scientists from over 25 institutions around the world have been involved in the project, hosted by Fermilab. The collaboration has already produced about 200 academic papers, with more to come.

From Chicago Sun-Times, Oct. 30, 2018: Fermilab Deputy Director Joe Lykken: “There’s a lot of hype out there, but I think it is a fair analogy to say this is like the World Wide Web when there were only three websites … We really are at the beginning of something that we think is going to be transformative, not just for science but for the whole world.”
