In December 2011, a new volcanic island began forming in the Red Sea, accompanied by lava fountains reaching up to 30 meters (95 feet) tall. By Jan. 14, 2012, when the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft captured this image (left), the island clearly showed a central crater, similar to the surrounding islands, and was well above the wave height. The right image is from Google Earth and shows the area before the creation of this new island. This region is part of the Red Sea Rift where the African and Arabian tectonic plates are pulling apart. The image covers an area of 5.6 by 9.3 kilometers (3.5 by 5.8 miles), and is located at 15.1 degrees north latitude, 42.1 degrees east longitude.

With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington, D.C.
