Good afternoon, Rallypoint, and again welcome to the Astronomy Picture of the Day (APOD) two-fer. Today's (February 13th) image is titled "Earth at Night." Also known as "The Black Marble," this image is a composite of hundreds of photos taken by the orbiting Suomi NPP (National Polar-orbiting Partnership) satellite. It is the first satellite mission to address the challenge of acquiring a wide range of land, ocean, and atmospheric measurements for Earth system science while simultaneously preparing to address operational requirements for weather forecasting. Suomi NPP was launched from Vandenberg Air Force Base in California on Oct. 28, 2011.

Thank you my space-exploration advocate friend Maj William W. 'Bill' Price for posting the February 13th Astronomy Picture of the Day (APOD): ‘Earth at Night’
Image: Earth at Night
Image Credit: NASA, Suomi NPP VIIRS; Data: Miguel Román (NASA GSFC); Processing: Joshua Stevens
Explanation: This is what the Earth looks like at night. Can you find your favorite country or city? Surprisingly, city lights make this task quite possible. Human-made lights highlight particularly developed or populated areas of the Earth's surface, including the seaboards of Europe, the eastern United States, and Japan. Many large cities are located near rivers or oceans so that they can exchange goods cheaply by boat. Particularly dark areas include the central parts of South America, Africa, Asia, and Australia. The featured image, nicknamed Black Marble, is actually a composite of hundreds of pictures remade in 2016 from data taken by the orbiting Suomi NPP satellite.
