ALT Dramatic image of Uranus captured by NASA’s Voyager 2 spacecraft in 1986, showing the planet as a thin, glowing crescent against the blackness of space. Only the outer edge of the planet is illuminated by the Sun, creating a soft, pale blue-green arc. The rest of Uranus fades into shadow, emphasizing its distant, cold, and mysterious nature. This image was taken as Voyager 2 departed the Uranian system, looking back toward the Sun.
