Space Shuttle Discovery
NASA considers shuttle shelf-life
(Aug 31, 2008)

NASA will study whether the space shuttle can operate beyond its planned retirement in 2010, reports say. The agency will look at what might be required to delay the retirement of its fleet until the shuttle's replacement – Ares-Orion – begins flying in 2015. The exercise is aimed at answering questions it expects on the matter from Congress and the incoming president.

Opportunity's tracks leaving Victoria Crater
Opportunity rover ascends to level ground
(Aug 31, 2008)

NASA's Mars Exploration Rover Opportunity has climbed out of the large crater that it had been examining from the inside since last September. Opportunity used its own entry tracks from nearly a year ago as the path for a drive of 6.8 meters (22 feet) bringing the rover out over the top of the inner slope and through a sand ripple at the lip of Victoria Crater.

Crab Nebula
Cosmic particle accelerator pinpointed in Crab Nebula
(Aug 29, 2008)

A powerful cosmic particle accelerator has been pinpointed in the Crab Nebula: a doughnut-shaped magnetic field surrounding the stellar corpse at the nebula's heart. The finding is based on a tricky measurement showing that high-energy radiation near the star is polarised, with its electric field lining up neatly with the star's spin axis.

Mars rover driving out of crater
(Aug 29, 2008)

NASA's robotic rover Opportunity is driving out of a giant crater on Mars nearly a year after its dangerous descent to examine exposed bedrock. The 800m-wide Victoria Crater lies on the Red Planet's Meridiani Plains. The impact depression has high walls with layers of exposed rock that should reveal clues to Mars' geological past.

NASA renames observatory for Fermi, reveals entire gamma-ray sky
(Aug 28, 2008)

NASA's newest observatory, the Gamma-ray Large Area Space Telescope, or GLAST, has begun its mission of exploring the universe in high-energy gamma rays. The spacecraft and its revolutionary instruments passed their orbital checkout with flying colors. NASA announced today that GLAST has been renamed the Fermi Gamma-ray Space Telescope. The new name honors Enrico Fermi, a pioneer in high-energy physics.

Clash of clusters provides another clue to dark matter
(Aug 28, 2008)

Another powerful collision of galaxy clusters has been captured with NASA's Chandra X-ray Observatory and Hubble Space Telescope. Like its famous cousin, the Bullet Cluster, this newly studied cluster, officially known as MACS J0025.4-1222, shows a clear separation between dark matter and ordinary matter. This helps answer a crucial question about whether dark matter interacts with itself in ways other than via gravitational forces.

Do galaxies have a minimum mass?
(Aug 28, 2008)

Some shine like disco balls and others [like W1 shown here] are barely visible. But the Milky Way's galactic companions all seem to weigh the same at their core, according to a new study. Since these dwarf galaxies are the smallest known, the find suggests there is a minimum amount of matter needed to form a galaxy.

Digging by NASA's Phoenix Mars Lander on Aug. 23, 2008, during the 88th sol (Martian day) since landing, reached a depth about three times greater than in any trench Phoenix has excavated. Credit: NASA
Phoenix digs deeper as third month nears end
(Aug 27, 2008)

The next sample of Martian soil being grabbed for analysis is coming from a trench about three times deeper than any other trench the Phoenix Mars Lander has dug. On Tuesday, Aug. 26, the spacecraft finished the 90 Martian days (or "sols") originally planned as its primary mission and will now continue into a mission extension through September.

Massive galaxy cluster to shed light on cosmic lumpiness
(Aug 26, 2008)

Astronomers have found the most massive distant cluster of galaxies yet seen. A search of the rest of the sky for such objects could help measure the lumpiness of the universe and the effects of dark energy, the mysterious entity that is causing space to expand ever faster.

Sky survey yields new cosmic haul
(Aug 25, 2008)

Astronomers looking through the data from the Sloan Digital Sky Survey, the world's largest survey of galaxies, have found a new haul of objects closer to home – including one, called SQ372 [circled in red] with a potentially exotic origin. By searching through a survey region known as Stripe 82, a team led by Andrew Becker of the University of Washington, has discovered almost 50 new asteroid-sized bodies in the outer regions of our Solar System.
