From Listverse, May 3, 2019: The Dark Energy Camera made this list of 10 brilliant feats of scientific technology, along with LIGO, the Pierre Auger Observatory and the Large Hadron Collider.

Members of the Dark Energy Survey have partnered with the LIGO experiment in the hunt for gravitational waves. They’re the DES-GW group. DES-GW will use the Dark Energy Camera to help LIGO search for the source of the gravitational waves it detects.

Scientists on the Dark Energy Survey have released the first in a series of dark matter maps of the cosmos. These maps, created with one of the world’s most powerful digital cameras, are the largest contiguous maps created at this level of detail and will improve our understanding of dark matter’s role in the formation of galaxies.

Pictured above are many types of galaxies captured by the Dark Energy Camera. At least five are easy to spot: the edge-on spiral on the right side, the pair of colliding spirals at the bottom center, a big spiral in the top-left and an elliptical on the far left.

On Thursday, workers mated the Dark Energy Camera 570-megapixel imager, seen here hanging from a crane, to the corrector optics of the Blanco telescope at the Cerro Tololo InterAmerican Observatory in Chile. This image was taken by the DECam webcam.

This month, Fermilab technicians and Dark Energy Survey collaborators installed the last of 62 science-quality charged coupling devices, or CCD’s, into the imager for the Dark Energy Camera currently housed at SiDet. CCDs work like film, and each one contains 8 million pixels. The camera also has another 12 CCDs of 4 million pixels each for guiding and focusing. The imager will head to Chile in mid-August for installation on the Blanco telescope. DES collaborators in Chile just finished installing the off-telescope components of the DECam imager liquid-nitrogen cooling system in preparation for the camera’s arrival.
