Announced the world's largest map the night sky: the total over 1 trillion pixels
scientists announced on the 11th by far the biggest night sky maps, presented the details than any previous image
composites of North Silver Crown . Color night figure by the maximum over the past 10 years, 2.8 trillion more than 700 ten thousand pixel images spliced together to obtain a pixel more than 1 trillion
composite image, Silver Crown, by a number of one million image synthesis
Daniel Thomas of Portsmouth University Dr. This picture is called "Science in the history of one of the largest free goods"
Jan. 11, scientists announced the biggest night sky map ever, with unprecedented detail of the universe we can see. Free access to the site the public can chart the night sky, it has therefore been called "the history of science one of the largest free goods."
This picture is an international plan Sloan Digital Sky Survey-III (hereinafter referred to as SDSS-III) crystallization of unremitting efforts, all available for free. Through this picture, both professional astronomers discovered the civilian astronomers can be staged. Scientists for the past 10 years, more than 700 ten thousand 2.8 million pixel image stitching together, eventually creating the biggest night sky map to date, more than 1 trillion pixels.
piece of tera-pixel image is very huge and amazing details, require 50 million to complete high-definition TV show. University of Portsmouth - the only part in the scheme of a British university - the 鲍勃尼科勒 professor, said: "This picture is the crystallization of 10 years of work, performed for many years can provide opportunities for a variety of scientific discovery . SDSS-III is an amazing program, established in the initial SDSS and SDSS-II survey program based on the estate. This picture is made unremitting efforts for decades the results of hundreds of people involved, drawn a lot of incredible discovery. in the provision of free public access to the data, the astronomical community has a rich tradition. We want everyone to like us, like this picture. "
this is the SDSS-III pictures published cooperation project the core of the new data is held in Seattle in the first session of the American Astronomical Society meeting 217 part. University of Portsmouth spokesman said that a picture using previously published data splicing, is by far the most abundant details of the synthesis of the night sky map. With SDSS data, it was discovered that nearly 500 million objects, including the asteroids, stars, galaxies and distant quasars.
addition to announcing the biggest night sky maps, scientists have announced the latest of all these objects the most accurate position, color and shape of the data. University of Portsmouth Institute of Cosmology and Gravitation, Dr. Daniel Thomas also participated in the SDSS-III. He vividly pointed out: "This is the history of science one of the largest free products. Had ambitious sky survey programs - such as the last century 50's Palomar Sky Survey - is still used as a reference, the scientists hope that the latest SDSS Data used to have a similar period. like this picture as Galaxy Zoo science projects such as the basis for the civilian population. A total of 25 million volunteers from the general public of the Galaxy Zoo, a number of categories to help millions of galaxies. using SDSS images, 'Google Sky 'and other online tools that allow anyone to tour the universe. "
biggest night sky map using photos taken since 1998, was used by the world's largest digital camera, specifically, is a 126 megapixel imaging detector, installed Apache Peak Observatory in New Mexico, a 2.5 m diameter telescope. In the past 10 years, SDSS-third of the entire sky area scanned. With this piece of new images, scientists can measure the Earth more than 100 million galaxies and the distance between the 3D map of the universe as a draw for new items - SDSS-III Baryon Oscillation Spectroscopic Survey project data.
scientists hope the project will help uncover the mystery of dark energy to understand the dark energy in the universe share. California, Lawrence Berkeley National Laboratory, Professor David 斯库勒格尔 said: "The dark energy is the biggest scientific mystery, in trying to uncover the mystery of the road, SDSS will continue to play leads the way in role.
