The city of Nome lies on the southern Seward Peninsula coast of Alaska, on the Bering Sea. The current population of 3800 is dwarfed by the boom engendered by the discovery of gold in 1899. Ten years later, Nome was the largest city in the Alaska Territory with a population of more than 20,000. By 1910, with the exhaustion of most of the gold, the population had fallen to 2600. The image was acquired on May 23, 2014, covers an area of 8.2 by 8.5 km, and is located at 64.5 degrees north, 165.4 degrees west.

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.
