Icy Crescent

Thu, 25 May 2017 04:48:37 +0000

The plumes of Enceladus are not visible in this shot. The geometry between the Cassini spacecraft, Enceladus, and Saturn allows for the illimuation of the moon by “Saturn-shine” but it also puts the region of those southern plumes in what we could call “deep shadow”. The effect can be illustrated By increasing the exposure on […]

This will continue until Saturn’s solstice in May 2017. At that point in time, the shadow will extend only as far as the innermost A […]
