  • This is one of the first images recorded by the Dark Energy Camera, the world's most-powerful digital camera. Built at Fermilab, a U.S.-run facility near Chicago, and mounted on a telescope at an observatory in Chile, the camera achieved first light on September 12.
  • The camera is roughly the size of a phone booth.
  • Able to see light from over 100,000 galaxies up to 8 billion light years away in each image, the camera is the most-powerful instrument of its kind.
  • Scientists believe something called "dark energy" is responsible for the acceleration of the universe's expansion, but have yet to understand what it is.

  • The Dark Energy Camera will have the world’s largest camera filter, seen here being unpacked at Fermilab for assembly onto the camera.

The World's Most Powerful Digital Camera

Published 19 September 2012

After work by scientists on three continents over eight years, the 570-megapixel Dark Energy Camera took its first pictures of the night sky over Chile on September 12. The Dark Energy Survey (DES) group hopes images taken by the camera can help answer one of the biggest mysteries in science: why the expansion of the universe is increasing.
