@burntbonez You mean, who took the picture?! An explanation is here:
The photo…was taken by Voyager 1 in 1990 as it sailed away from Earth, more than 4 billion miles in the distance. Having completed its primary mission, Voyager at that time was on its way out of the Solar System, on a trajectory of approximately 32 degrees above the plane of the Solar System. Ground Control issued a command that directed the distant space craft to turn around and, looking back, take photos of each of the planets it had visited. From Voyager’s vast distance, the Earth was captured as a infinitesimal point of light…actually smaller than a single pixel of the photo…Quite by accident, the Earth was captured in one of the scattered light rays caused by taking the image at an angle so close to the Sun.
There’s a Wikipedia article, too, which notes that the photo was taken at Sagan’s request.
Voyager 1 was in the news just today!
