Vanderbilt’s role in largest digital sky image
The Sloan Digital Sky Survey-III collaboration, which includes Vanderbilt University, has resulted in a picture of the sky so big that it would take 500,000 high-definition TVs to view it at full resolution. The color image contains more than a trillion pixels and covers about one-third of the entire sky. Read MoreJan 13, 2011
