The project Sloan Digital Survey III (SDSS-III) have released the digital color image ever taken of larger whole sky. The photograph more than a billion pixels has been developed over the last decade with millions of snapshots of 2.8 megapixels and the work of hundreds of people.
The image is so large and detailed that it would take 500,000 HDTV to view it in full resolution. Thanks to its precision, "will provide many new opportunities for scientific discovery in the coming years," says Bob Nichol, a professor at the University of Portsmouth and scientific spokesman SDSS-III.
The truth is that this new image, presented at the meeting of the American Astronomical Society held in Seattle, offers astronomers a global view of the night sky like never before achieved. At first glance, without going, it seems an amalgam of material, but in reality, all these points golden hide much of the wealth of the universe. The data from the Sloan Digital Survey have been used to discover nearly 500 million astronomical objects, including asteroids, stars, galaxies and distant quasars. The latest and most accurate positions of these objects is now what we can all observe. REWARD
HISTORICAL
"This is one of the greatest rewards in the history of science," says Mik satisfied Blanton, of the University of New York , who directs the work of the data file SDSS-III. Blanton and others have worked for months preparing for the development of all these data. "They are a legacy for history," he says.
Image began in 1998 with what was then the largest digital camera in the world, an image detector of 138 megapixels located in the Apache Point Observatory in New Mexico (U.S.). Project leaders say that this huge image has formed the basis for new records, the sky using the SDSS telescope. From the spectrum, scientists can discover what are the distances to galaxies and the properties of stars, as its temperature or chemical composition. The measurement of these data started in 2009 and continue until 2014. Once completed, scientists will get the largest 3-D map of galaxies ever conducted. These measures will also help astronomers understand the nature of dark energy.
