Gas between galaxies helps case for dark energy
Using observations of 3,000 quasars discovered by the Sloan Digital Sky Survey, scientists have made the most precise measurement to date of the cosmic clustering of diffuse hydrogen gas. These quasars -- 100 times more than have been used in such analyses in the past -- are at distances of eight to ten billion light years, making them among the most distant objects known.

Space station status report -- The International Space Station's Expedition 9 crewmembers are now past the halfway point of their six-month mission. This week, they prepared for a third spacewalk and joined the world in observing the 35th anniversary of the first landing of humans on the moon.
Statement from ISS Heads of Agency meeting -- The space agency leaders from the United States, Russia, Japan, Europe and Canada met Friday to discuss International Space Station cooperation activities. At this meeting, the partnership unanimously endorsed the station technical configuration and reviewed the status of on-orbit operations and plans. The new ISS configuration is planned for completion by the end of the decade and will accommodate on-orbit elements from each of the ISS Partners. The configuration will enable increased utilization and will provide early opportunities for an enhanced crew of greater than three people.
