The crescent moons of Uranus
amateur image processing,
Voyager 1 and 2
As Voyager 2 departed the Uranus system on January 26, 1986, it turned back to point its cameras at Uranus and its five major moons. At such a high phase angle, very little light was reflected from the moons to Voyager's camera, so their images were almost lost among background noise. Heavy processing was required to bring their slim crescents into view. They are, from left to right, Oberon, Titania, Umbriel, Ariel, and Miranda.
