Holden Crater
Mars crater's ancient lakes may have been habitable
(Mar 8, 2008)

Clay-encrusted boulders recently discovered on Mars are evidence of ancient and perhaps once-habitable lakes, a new study finds. The High Resolution Imaging Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter (MRO) spotted the house-sized rocks, called megabreccia, in the 154-km-wide Holden Crater.

Large Binocular Telescope
Giant telescope opens both eyes
(Mar 7, 2008)

The world's most powerful optical telescope has opened both of its eyes. Astronomers at the Large Binocular Telescope (LBT) in Arizona have released the first images taken using its two giant 8m diameter mirrors. The detailed pictures show a spiral galaxy located 102 million light-years away from the Milky Way.

Saturn's moon Rhea may have rings
(Mar 7, 2008)

Cassini spacecraft has found evidence of material orbiting Rhea, Saturn's second largest moon. This is the first time rings may have been found around a moon. A broad debris disk and at least one ring appear to have been detected by a suite of six instruments on Cassini specifically designed to study the atmospheres and particles around Saturn and its moons.

Universe submerged in a sea of chilled neutrinos
(Mar 6, 2008)

We are all submerged in a sea of undetectable particles left over from the first few seconds of the big bang, according to the latest observations from a NASA satellite. The Wilkinson Microwave Anisotropy Probe (WMAP) has confirmed the theory that the universe is filled with a fluid of cold neutrinos that remain almost entirely aloof from ordinary matter.

NASA spacecraft photographs avalanches on Mars
(Mar 5, 2008)

A NASA spacecraft in orbit around Mars has taken the first ever image of active avalanches near the Red Planet's north pole. The image shows tan clouds billowing away from the foot of a towering slope, where ice and dust have just cascaded down. The High Resolution Imaging Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter took the photograph Feb. 19.

Colliding black holes may leave infrared glows
(Mar 4, 2008)

Supermassive black holes could leave behind long-lasting infrared afterglows visible to current instruments when they merge, a new study says. If so, scientists could find signs of these mergers much sooner than expected.

Mars gulley
Liquid water found flowing on Mars? Not yet
(Mar 3, 2008)

Liquid water has not been found on the surface of Mars within the last decade after all, according to findings by a University of Arizona researcher and his colleagues. The finding casts doubt on the 2006 report that the bright spots in some Martian gullies indicate that liquid water flowed down those gullies sometime since 1999.

Endeavour being rolled to the launch pad
NASA gives 'Go' for Space Shuttle launch On March 11
(Mar 2, 2008)

NASA's mission management team decided Friday that March 11 at 2:28 a.m. EDT is the official launch time for space shuttle Endeavour's STS-123 mission. The crew will deliver the first segment of a Japanese laboratory complex called Kibo, plus a new Canadian robotics system to complement the station's robot arm.

Nearest star's wobbles could reveal Earth's twin
(Mar 1, 2008)

Another Earth may be orbiting the star next door, and we could detect its presence within a few years, a new study argues. A telescope trained permanently on Alpha Centauri should be able to pick up the slight stellar wobbles induced by a small, rocky, Earth-like planet.
