The United States' National Aeronautics and Space Administration (NASA) likened railroads and highways in Turkey's capital Ankara to arteries in an eagle-eye shot of the city at night, dubbed "photo of the day" on June 28.
"If Ankara is the geographic and political heart of Turkey, the railroad and highway systems certainly act as the arteries. These well-lit transportation networks encircle and radiate outward from the city center," said a short piece about the March 25 shot.
NASA also distinguished between the light and white lights emitting from the city, noting that the colors come from different types of light bulbs and could be used to identify industrial and residential areas.
"The industrial [municipality] of Sincan, for example, emits powerful white light, while yellow streetlights add a warm glow to neighborhoods that show up with signature red rooftops during the day."
NASA also noted the distinct aerial image of the Atatürk Mausoleum, where the Turkish Republic's founding father is buried.
Encompassed by a large campus, the monument appears as a dark blot with different lighting from its surroundings.
