The next most powerful survey telescope is the 4-meter Blanco and its Dark Energy Camera. The DECam's field of view is bigger than Subaru's, but the telescope's mirror has only a fourth as much collecting area, meaning it's less sensitive to faint objects.
Caption: PLANETARY HERALD These discovery images show the distant object 2012 [VP.sub.113] (arrows), taken about 2 hours apart on November 5, 2012, with the Dark Energy Camera. The author found the object thanks to 2012 [VP.sub.113]'s motion against the background of stars and galaxies.
Caption: HIGH-POWERED CAMERA The Dark Energy Camera, installed on the 4-meter Blanco telescope in Chile, includes everything from the big black box at far left down to the red ring.
The Dark Energy Camera is the most powerful survey instrument of its kind.
They were created using data captured by the Dark Energy Camera, a 570-megapixel imaging device that is the primary instrument for the Dark Energy Survey (DES).
Scientists in the international Dark Energy Survey collaboration announced this week that the Dark Energy Camera, the product of eight years of planning and construction by scientists, engineers and technicians on three continents, has achieved first light.
"The achievement of first light through the Dark Energy Camera begins a significant new era in our exploration of the Cosmic Frontier," said James Siegrist, DOE associate director of science for high-energy physics.
The Dark Energy Camera is the most powerful survey instrument of its kind, able to see light from over 100,000 galaxies up to 8 billion light-years away in each snapshot.
Sheppard and Trujillo used the new Dark Energy Camera (DECam) on the NOAO 4 meter telescope in Chile for discovery.
Three of the cameras--the Dark Energy Camera on the 4-meter Blanco Telescope on Cerro Tololo, Chile; the Hyper Suprime-Cam on the 8.2-m Subaru telescope on Mauna Kea; and the One Degree Imager on the 3.5-m WIYN telescope on Arizona's Kitt Peak--are among the largest digital cameras ever made.
A typical major observatory telescope might have a handful of CCDs tiling its focal plane, but the Dark Energy Camera and One Degree Imager each have more than 60 CCDs in their arrays, and the Hyper Suprime-Cam has 116.
