NASA Chandra Research: New Findings About Dark Energy

A powerful and independent method was used to probe dark
energy using NASA’s Chandra X-ray Observatory. The results on
cosmic acceleration provide clues about the nature of dark
energy and the fate of the universe.

Team leaders will present findings at a Space Science Update
(SSU) at 1 p.m. EDT, May 18, 2004. It is in the Webb
Auditorium, NASA Headquarters, 300 E St. SW, Washington.
