One of the most widely known photographs of Earth, this image was taken by the crew of the final Apollo mission as the crew made its way to the Moon. Dubbed the “Blue Marble,” Earth is revealed as both a vast planet home to billions of creatures and a beautiful orb capable of fitting into the pocket of the universe.  NASA

The Blue Marble is a photograph of Earth taken on December 7, 1972, by either Ron Evans or Harrison Schmitt aboard the Apollo 17 spacecraft on its way to the Moon. Viewed from around 29,400 km from Earth’s surface, a cropped and rotated version has become one of the most reproduced images in history. In the original NASA image, named AS17-148-22727 and centered at about 26°19′49″S 37°25′13″E with the South Pole facing upwards, The Blue Marble shows Earth from the Mediterranean Sea to Antarctica. Wikipedia
