At 3.7 billion miles, I will guess this photo was taken by a Voyager space craft or the New Horizons space craft?
Where would the sun be located if this photo was significantly enlarged?
"In the photograph, Earth's apparent size is less than a pixel; the planet appears as a tiny dot against the vastness of space, among bands of sunlight reflected by the camera.[1]"
Amazimgly...chips I helped build in my youth are probably on both those Voyager space craft. It is my belief that they have left our solar system and are now streaking outward in deep space.
