The Pale Blue Dot is an iconic 1990 photograph of Earth taken by NASA's Voyager 1 from 3.7 billion miles (6 billion km) away. Proposed by astronomer Carl Sagan, it shows Earth as a tiny speck—less than a pixel—suspended in a sunbeam. The image inspired Sagan's book, "Pale Blue Dot: A Vision of the Human Future in Space," emphasizing humanity's shared, fragile home. #trending #space #spacefacts #theuniverse #home | Romario Jack
