The Dark Energy Survey (DES) will use its newly constructed camera, DECam, to observe a large swath of the southern sky out to vast distances in order to provide new clues about the nature of dark energy or why the universe’s expansion is accelerating. The DECam imager was designed and built at Fermilab over the… More »

DECam Update

Starting in 2012 and continuing for 5 years, the Dark Energy Survey (DES) will use its newly constructed camera, DECam , to observe a large swath of the southern sky out to vast distances in order to provide new clues about the nature of dark energy – or why the universe’s expansion is accelerating.
