The largest map of its kind ever created, researchers hope it can help the investigation of mysterious dark matter and dark energy that make up 96 percent of the universe. The map was produced by the Sloan Digital Sky Survey. Early last year, it released the largest-ever image of the sky, which covered one-third of the night sky. The new data, “Data Release 9” (DR9), which publically releases the data from the first two years of this six-year project, begins expansion of this earlier image into a full three-dimensional map.
