[Wednesday, May 2, 2007] Using observations by NASA's Mars Odyssey orbiter, scientists have discovered that water ice lies at variable depths over small-scale patches on Mars.

[Friday, May 4, 2007] COROT has provided its first image of a giant planet orbiting another star and the first bit of 'seismic' information on a far away, Sun-like star- with unexpected accuracy. 

[Wednesday, May 9, 2007] A U.S. Air Force C-17 cargo aircraft carried NASA's Phoenix Mars Lander spacecraft Monday, May 7, from Colorado to Florida, where Phoenix will start a much longer trip in August.

[Wednesday, May 9, 2007] For the first time, astronomers have created a rough map of a planet orbiting a distant sun-like star, employing a technique that may one day enable mapping of Earth-like worlds.

[Wednesday, May 9, 2007] NASA is awarding five-year grants to four research teams that will become new members of the NASA Astrobiology Institute (NAI).

[Friday, May 11, 2007] It's a planet Goldilocks would relish. Scientists are calling Gliese 581C "just right" for supporting life. The newly-discovered planet is not too hot, not too cold ... which means it could harbor liquid water.

[Tuesday, May 15, 2007] Scientists this week begin the final leg of a five-year, NASA-funded mission to reach the bottom of Cenote Zacatón in Mexico, the world's deepest known sinkhole.

[Wednesday, May 16, 2007] Cracks in the icy surface of Saturn's moon Enceladus open and close daily under the pull of Saturn's gravity, according to new calculations by NASA-sponsored researchers.

[Saturday, May 19, 2007] A spacecraft called Phoenix is destined to land on Mars in 2008, seeking to unravel some of the mysteries of the red planet.

[Saturday, May 19, 2007] New information gathered by three particle spectrometers aboard the Cassini spacecraft shows tholin formation happens in Titan's atmosphere at altitudes greater than 1,000 km. The results also show tholins form differently than previously thought.

[Monday, May 21, 2007] Soil analyzed by Spirit is so rich in silica that it may provide strong evidence that ancient Mars was much wetter than it is now. The processes that could have produced such a concentrated deposit of silica require the presence of water.

[Wednesday, May 23, 2007] Astronomers have discovered a system of two Jupiter-like planets orbiting a star whose composition might seem to rule out planet formation. This NASA-funded study has implications for theories of planet formation.

[Wednesday, May 23, 2007] On May 12, 2007, Cassini completed its 31st flyby of Saturn's moon Titan, which the team calls T30. The radar instrument obtained this image showing the coastline and numerous island groups of a portion of a large sea.

[Thursday, May 24, 2007] Stanley L. Miller, whose famous laboratory experiments in 1952 demonstrated how the simple organic compounds considered necessary for the origin of life could have been synthesized on the primitive Earth, died yesterday. He was 77.

[Thursday, May 24, 2007] Scientists from all over the world will meet in San Juan, Puerto Rico, in July to report on latest findings in the study of the origin, evolution, distribution, and future of life in the universe, at Bioastronomy 2007.

[Friday, May 25, 2007] Recent insights from the biological sciences on how organisms thrive in "extreme" environments have not yet been incorporated into the scientific strategies for detecting whether life exists or has ever existed on Mars.

[Friday, May 25, 2007] The High Resolution Stereo Camera (HRSC) on board ESA's Mars Express has captured breathtaking images of the Deuteronilus Mensae region on Mars.

[Tuesday, May 29, 2007] Ever dreamed of taking part in an expedition among an international crew of scientists and engineers? Well here is your chance to participate in the Arctic Mars Analog Svalbard Expedition 2007.

[Tuesday, May 29, 2007] The world's largest and most prolific team of planet hunters announced today (Monday, May 28) the discovery of 28 new planets outside our solar system, increasing to 236 the total number of known exoplanets.

[Wednesday, May 30, 2007] The NAI passed two major milestones in the last month: awards from the 2007 Director’s Discretionary Fund (DDF) and the selection of four new teams from the 4th Cooperative Agreement competition.
