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.
Landing technology tested for future spacecraft
Lockheed Martin has successfully performed a series of drop tests at the U.S. Army Yuma Proving Ground in Yuma, Ariz., to validate soft landing technology that can be used for astronaut crew capsules upon return to Earth.

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.

A day in the lives of galaxies
Like a photographer clicking random snapshots of a crowd of people, NASA's Hubble Space Telescope has taken a view of an eclectic mix of galaxies. In taking this picture, Hubble's Advanced Camera for Surveys was not looking at any particular target. The camera was taking a picture of a typical patch of sky, while Hubble's infrared camera was viewing a target in an adjacent galaxy-rich region.
Cassini sees the moon Tethys: The Sea Goddess
Like a half-full moon, cratered Tethys hangs before the Cassini spacecraft in this narrow angle camera view. Voyager images showed a large fracture on Tethys about 470 miles long. Cassini will investigate this and other features on Tethys during two planned flybys beginning next year.

Newborn star provides info on solar system's origin
A new study has caught a newborn star similar to the sun in a fiery outburst. X-ray observations of the flare-up, which are the first of their kind, are providing important new information about the early evolution of the sun and the process of planet formation.
NASA goes to the 'SORCE' of Earth sun-blockers
Scientists using measurements from NASA's Solar Radiation and Climate Experiment (SORCE) satellite have discovered that Venus and sunspots have something in common: they both block some of the sun's energy going to Earth.
