The “pale blue dot” picture is 20 years-old.
Taken in 1990 by NASA’s Voyager 1 spacecraft, the “pale blue dot” photo shows what our planet looks like from four billion miles away. Earth is the tiny speck of light indicated by the arrow, and enlarged in the upper left-hand corner. The pale streak over Earth is an artifact of sunlight scattering in the camera’s optics.
