This image of Saturn's giant moon Titan is a composite of three infrared bands captured by the Near Infrared Camera-2 on the 10-meter Keck II telescope. It was taken by astronomer Antonin Bouchez on June 7, 2011. Each infrared band was assigned a color: red, green and blue. The three were then merged to make this false-color image. The brightening at the limb of the moon is probably due to the thicker amount of atmosphere that is being viewed at such an oblique angle.
