Getting a full picture of an elusive subject

The recent work on Abell 383 provides one of the most detailed 3-D pictures yet taken of dark matter in a galaxy cluster. By Chandra X-ray Center, Cambridge, Massachusetts — Published: March 15, 2012
Two teams of astronomers have used data from NASA’s Chandra X-ray Observatory and other telescopes to map the distribution of dark matter in a galaxy cluster known as Abell 383, which is located about 2.3 billion light-years from Earth. Not only were the researchers able to find where the dark matter lies in the two dimensions across the sky, but they were also able to determine how the dark matter is distributed along the line of sight.
