Nighttime Image of Texas Cities Posted: 06 Jul 2013 06:59 AM PDT One of the Expedition 36 crew members aboard the International Space Station, some 240 miles above Earth, used a 50mm lens to record this oblique nighttime image of a large part of the nation's second largest state in area, including the four largest metropolitan areas in population. The extent of the metropolitan areas is easily visible at night due to city and highway lights. The largest metro area, Dallas-Fort Worth, often referred to informally as the Metroplex, is the heavily cloud-covered area at the top center of the photo. Neighboring Oklahoma, on the north side of the Red River, less than 100 miles to the north of the Metroplex, appears to be experiencing thunderstorms.  The Houston metropolitan area, including the coastal city of Galveston, is at lower right. To the east near the Texas border with Louisiana, the metropolitan area of Beaumont-Port Arthur appears as a smaller blotch of light, also hugging the coast of the Texas Gulf. Moving inland to the left side of the picture one can delineate the San Antonio metro area. The capital city of Austin can be seen to the northeast of San Antonio. Original Source
