Dark energy is a  mysterious force pushing the universe apart as well as accelerating its  expansion, and remains &#8220;perhaps the biggest mystery in physics,&#8221;  according to study leader Steve Allen from the Institute of Astronomy at  the University of Cambridge in England. Allen and his team used the  Chandra telescope to study 26 clusters of galaxies located 1 billion to 8  billion light years away. The researchers measured the distances to the  clusters, and then by plotting those distances over time, they  determined that the expansion of the universe started speeding up about 6  billion years ago. This acceleration, they state, is due to dark  energy. Study coauthor Andy Fabian, also from the Institute of  Astronomy, stated in a press release: &#8220;The new Chandra results suggest  the dark energy density does not change quickly with time and may even  be constant.&#8221; If it does remain constant, the universe is expected to  expand forever. The team&#8217;s findings also agree with other estimates that  dark energy makes up about 75 percent of the universe. The study will  appear in a forthcoming issue of the <em>Monthly Notices of the Royal  Astronomy Society.<\/em> <\/span><\/p>\n<h6><em>This news brief appeared in the Discoveries column of the <\/em>Boston Globe&#8217;s<em> Health\/Science section on 5\/25\/2004.<\/em><\/h6>\n","protected":false},"excerpt":{"rendered":"<p>A new study using NASA&#8217;s orbiting Chandra X-ray Observatory seems to confirm the existence of dark energy, which may have implications for the ultimate fate of the universe.
