The above satellite image was captured on by a NASA satellite on January 16, 2018 and shows criss-crossing cloud bands caused by ships in the eastern Atlantic Ocean off Spain and Portugal.
Although the white trails look vaguely like contrails left behind by airplanes, they actually result from ship exhaust.
The narrow clouds, known as ship tracks, form when water vapor condenses around microscopic pollution particles that ships emit as exhaust. Due to smaller and more abundant particles than those of the surrounding clouds, the ship trails typically are brighter and thicker in appearance and with easily defined boundaries.
A bank of clouds off North America’s west coast featured a series of white trails captured October, 5 2009.
