On this day in 1990, the Voyager 1 space probe took a photo of our planet from approximately 6 billion kilometers (3.7 billion miles) away.

"Commissioned by NASA and resulting from the advocacy of astronomer and author Carl Sagan, the photograph was interpreted in Sagan's 1994 book, Pale Blue Dot, as representing humanity's minuscule and ephemeral place amidst the cosmos."
