View of the Golden Record carried by Voyagers 1 and 2 as a greeting to any intelligent life which may find them. The record gives audio and visual information about Earth and its people, including greetings in 55 languages. At upper left are details of how to play the record to listen to the sounds, with information on viewing the images at right. The circle in the rectangle is the first image, so aliens will know their interpretation is correct. The lines at lower left show Earth's position relative to 14 pulsars. The 2 circles at lower right represent the hydrogen atom. The Voyagers were launched in 1977, and will reach nearby stars in 40,000 years.
