- High-res images spell new era in Earth sciences
04-06-2007 · EurekAlert!
High-resolution images that reveal unexpected details of the Earth's internal structure are among the results reported by MIT and Purdue scientists in the March 30 issue of Science. The researchers adapted technology developed for near-surface exploration of reservoirs of oil and gas to image the core-mantle boundary some 2,900 kilometers, or 1,800 miles, beneath Central and North America.

- NASA's New Mars Camera Gives Dramatic View Of Planet
09-30-2006 · ScienceDaily
Mars is ready for its close-up. The highest-resolution camera ever to orbit Mars is returning low-altitude images to Earth from NASA's Mars Reconnaissance Orbiter. Rocks and surface features as small as armchairs are revealed in the first image from NASA's Mars Reconnaissance Orbiter since the spacecraft maneuvered into its final, low-altitude orbital path. The imaging of the red planet at this resolution heralds a new era in Mars exploration.

- NASA and USGS produce most detailed satellite views of Antarctica
03-07-2007 · EurekAlert!
Researchers from NASA and the U.S. Geological Survey (USGS), Golden, Colo., have woven together more than a thousand images from the Landsat 7 satellite to create the most detailed, high-resolution map ever produced of Antarctica. The Landsat Image Mosaic of Antarctica (LIMA) offers views of the coldest continent on Earth in 10 times greater detail than previously possible.

- New breakthroughs in geological dating imminent
08-22-2007 · EurekAlert!
A breakthrough in geological dating can be expected within the next few years, combining existing methods to yield higher accuracy over longer time scales closer to the earth's origin. This will bring great benefits not just for earth sciences, but also for other fields that rely on accurate dating over geological time. The developments ushering in a new generation of dating methods were discussed at a recent workshop on geochronological timing organized by the European Science Foundation.

- Morning forecast on Titan calls for widespread methane drizzle off Xanadu
10-11-2007 · EurekAlert!
New near-infrared images from Hawaii's Keck Observatory and Chile's Very Large Telescope show for the first time a nearly global cloud cover at high elevations on Titan and a widespread and persistent morning drizzle of methane on the flanks of Titan's major continent, Xanadu. UC Berkeley astronomers Imke de Pater and Mate Adamkovics report these observations this week in Science Express and at the AAS's Division for Planetary Sciences meeting.

- Imaging quantum entanglement
09-21-2007 · EurekAlert!
An international team including scientists from the London Center for Nanotechnology today publishes findings in the journal Proceedings of the National Academy of Sciences demonstrating the dramatic effects of quantum mechanics in a simple magnet. The importance of the work lies in establishing how a conventional tool of material science -- neutron beams produced at particle accelerators and nuclear reactors -- can be used to produce images of the ghostly entangled states of the quantum world.
