Carl Sagan is most notably remembered for his gift of translating scientific undertakings into the language of human emotion.

He is less often credited as one of the driving factors behind Voyager's Golden Record. In 1977, Sagan gathered a group of scientific and cultural advisors that built a collection of 115 images, natural sounds from Earth, a selection of music, and greetings recorded in 59 languages that travel through space to greet any life-forms that might come across the record's path.
