Taken in 1990 by NASA's Voyager 1 spacecraft, the "pale blue dot" photo shows what our planet looks like from 4 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.
The 12-inch gold-plated records contain greetings in 59 languages, samples of music from different cultures and eras, and natural and human-made sounds from Earth. One record is currently 16.89 billion km from Earth, the other is over 13 billion km away.
