The Pale Blue Dot is a photograph taken of the Earth by the Voyager I spacecraft from a distance of about 6 billion kilometers. As the space probe passed Pluto, it was turned around to capture one last image of the Earth before continuing its journey beyond the solar system. In the photo, the Earth appears as a minuscule point of light, surrounded by the vast emptiness of the cosmos. The inspiration for Suspended in a Sunbeam comes from a speech given by Carl Sagan about the photo.
