Image Caption: Southwestern USA at night

This moonlit panorama was shot recently with a wide-angle lens by astronauts aboard the International Space Station (ISS), as they looked southwest from a point over Nebraska. The wide-angle lens shows a huge swath of country that stretches from Portland, Oregon (image right) to Phoenix, Arizona (image left). The largest string of lights is the Ogden-Salt Lake City-Provo area (lower center) in Utah. The Los Angeles and San Francisco metropolitan regions, and the cities of the central valley of California (Bakersfield to Redding) stretch across the horizon. The green airglow layer always appears in night images. Moonlight shows the red tinge of the ISS solar arrays top left.

Moonlight emphasizes the broader-scale geological zones. Nevada's short, dark, parallel mountain ranges of the basin and range geological province (image center) contrast with the expanses of flat country of the Colorado Plateau (image left) in Colorado, Arizona, Utah, and New Mexico. The near-full moon even reveals the vast dry lake bed known as the Bonneville Salt Flats. The black line of the Sierra Nevada marks the edge of California's well-lit central valley (in this image, directly below the San Francisco Bay area).
