NASA : Great Exuma Island, Bahamas .- Isla de Gran Exuma, de Las Bahamas

Hola amigos: A VUELO DE UN QUINDE EL BLOG., Un astronauta a bordo de la Estación Espacial Internacional tomó esta fotografía de los pequeños cayos de la isla en las Bahamas y los canales de marea prominentes de corte entre ellos. Para los astronautas, este es uno de los puntos más reconocibles del planeta.
La cadena de cayos - estiramiento 14.24 kilómetros (8.9 millas) en esta imagen - se extiende al oeste de Great Exuma Island (a las afueras de la imagen a la derecha). Exuma es conocido por ser alejado de las islas más grandes de las Bahamas, y es rica en cayos de propiedad privada y con la historia de pirata real (incluyendo el Capitán Kidd).

Small islands in the Bahamas photographed from low Earth orbit

An astronaut aboard the International Space Station took this photograph of small island cays in the Bahamas and the prominent tidal channels cutting between them. For astronauts, this is one of the most recognizable points on the planet.

The string of cays — stretching 14.24 kilometers (8.9 miles) in this image — extends west from Great Exuma Island (just outside the image to the right). Exuma is known for being remote from the bigger islands of The Bahamas, and it is rich with privately owned cays and with real pirate history (including Captain Kidd).

Small tidal changes on the banks cause great quantities of water to flow daily through the narrow channels between the cays, first in one direction and then the other. The darker blue sections are the deepest parts of the channels, where the water flow has cut through the rock ridge that makes the line of cays. The surrounding water is shallow (less than 25 meters, or 80 feet) and appears light blue.

Thanks to the astronaut’s steady hands in controlling a long lens in weightlessness, this photograph is detailed enough to show a single aircraft and its twin condensation trails.

Astronaut photograph ISS044-E-18893 was acquired on July 19, 2015, with a Nikon D4 digital camera using an 1150 millimeter lens, and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by a member of the Expedition 44 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed.
