Scientists with the Sloan Digital Sky Survey (SDSS-II) have used a novel technique to peer through the nature of dark energy as far as ten billion years ago and measure the three-dimensional structure of the distant Universe. Tracing this 3-D map scientists were able to assess the influence of dark energy over time, which might help unravel […]
The Dark Energy Camera (DECam) is the most powerful sky survey instrument yet built, a collaborative international effort which took more than eight hard years worth of planning and design. Recently, the camera, installed on top of a mountain in Chile at the Victor Blanco Telescope at the Cerro Tololo Inter-American Observatory, was tested for the first time and […]
Previously, we shared the largest and, respectively, most detailed 3-D maps of the Universe released by the Sloan Digital Sky Survey. Now the survey has released a new, massive update to the map, again, making it the largest 3-D map of the Universe, which pinpoints the locations and distances of over a million galaxies. Were you […]
Encompassing years worth of work, the Sloan Digital Sky Survey (SDSS-III) has now precisely measured the distance between over a quarter of a million galaxies. As part of the project, called the Baryon Oscillation Spectroscopic Survey, or BOSS, scientists built a massive map of all the studied galaxies so far, some more than six billion years ago […]
Unveiled this past weekend, astronomers from the Sloan Digital Sky Survey have created a 3D map of the Universe using the light from 14,000 quasars, some of the brightest bodies in the universe, to illuminate gas clouds in regions of space some 11 billion light years away. From the study‘s abstract: These features arise as […]
