Scientists from the SLAC National Accelerator Laboratory have produced the earth ’s first 3,200 - megapixel digital photograph . The images were snap by an oversized digital television camera destined for the Vera C. Rubin Observatory in Chile , in what is an early demo of this quickness ’s tremendous potential .
A picture containing 3.2 billion pixels is difficult to envisage . You would call for 378 4 G ultra - high - definition boob tube to expose one at its full resolution , grant to a SLACpress release .
Wow . Now imagine this top executive use to astronomy . Happily , that ’s precisely the plan , as the SUV - sized camera used to give rise these image will eventually be install on the Vera C. Rubin Observatory in Chile , which is likewise under construction .

Once Rubin is up and scat ( hopefully in the next year or two ) , the 3,200 - megapixel digital camera , or more succinctly , the world ’s first 3.2 - gigapixel tv camera , will fascinate a succession of bird’s-eye image of the entire southern sky , which it will do once every few years for 10 years . This task , known as theLegacy Survey of Space and Time , will track the motions of 1000000000000 of star and coltsfoot while create theworld ’s largest astronomical movie . This next - gen observatory is poise to pour forth young light on the organization of the universe , dark matter , and dark energy .
The new images , which can be seenhere , were created as a examination of the arrangement ’s newly complete focal planer , which wait on as the “ eye ” of the television camera . To take these photos , the squad used a 150 - micron pinhole to project images onto the focal plane . During test , the SLAC research worker project various objects , include a head of romanesco — a character of Brassica oleracea italica with a highly elaborate surface . Interestingly , the focal sheet involve to be chilled in a cryostat chamber and brought down to -150 degrees Fahrenheit in order for it to work by rights .
The focal plane , which measures more than 2 feet wide ( 0.6 meters ) , contains 189 individual detector , or flush - coupled gimmick , each of which can capture 16 - megapixel image . Each wanton - gathering picture element is 10 microns full — tiny , yes , but 10 times orotund than the picture element in a typical photographic camera phone ( for reference , the average human hair is 50 microns spacious ) . The focal plane is also super - flat , measuring around a tenth the width of a human whisker , allowing for exceptionally crisp , penetrating prototype . Multiple sets of nine flush - pair gimmick were assembled into square dubbed “ rafts , ” of which 21 were install onto the focal woodworking plane , along with four specialty rafts used for geomorphologic purposes . This command six month of deliberate study , as the spate , which cost $ 3 million each , are extremely fragile .

The specs on this digital camera are nothing short of remarkable . At 3,200 - megapixels , it could resolve a golfball from 15 miles away ( 24 km ) , and its athletic field of view is big enough to include 40 full moons . It will be able to spot objects 100 million time dimmer than those visible to the unaided middle , which would be like seeing a candle from a few thousand knot away .

The SLAC researchers are planning to tot the tv camera ’s lens , shutter , and filter exchange organisation later this year . Once examination is complete , the machine will be channelise to Chile and installed on the Rubin lookout station , which could pass off as early as mid-2021 . Should all go well , the LSST undertaking will start in 2022 and run until 2032 .
