Seeing Earth from the vantage point of space is always a humbling experience. This image, which shows a crescent shaped Earth and Moon, taken on September 18th 1977, is no different. The image was taken from a distance of 11.66 million kilometres from Earth- but there is something else that makes this so special.
This image depicts the start of a long journey of interstellar travel. The spacecraft, of course, is NASA’s Voyager 2. Voyager 1 & 2 have travelled farther from Earth than any other manmade object.
Voyager 1 famously delivered an image of Earth from 6.4 billion kilometres away known as “The pale blue dot”.
Today, voyager 1 & 2 can be found in the Heliosheath; the outermost layer of the heliosphere.
