Penn State scientists help construct largest 3-D map of the universe
8/8/12
The Sloan Digital Sky Survey III (SDSS-III), an international collaboration that includes Penn State astronomers, has produced the largest-ever three-dimensional map of massive galaxies and distant black holes. The new map will help to explain the mysterious "dark matter" and "dark energy" that scientists know makes up 96 percent of the universe. The map is the first in a series planned during a six-year project that will fully expand into three dimensions the largest-ever 2-D image of the sky, which the SDSS-III released early last year.
