Saturn’s moon Mimas is held in the centre of the frame; Epimetheus moves behind it. Photographed by Cassini, 3 October 2007.
The comet Hartley 2, photographed by Deep Impact as part of its extended EPOXI mission, 4 November 2011.
The original photos from this encounter were blurry (I’ve uploaded an almost equivalent gif here for comparison) because of a problem with the lens. By pointing the camera at a star, effectively a point-source of light, and studying the precise way in which the point got blurred, the EPOXI team was able to work backwards and “deconvolve” the photos of Hartley 2. This procedure makes them much sharper, but also introduces some ringing artefacts, which are especially visible in the first few frames.
Helene receding, with Saturn in the background. Photographed by Cassini, 3 March 2010.
Saturn’s moon Iapetus, photographed by Cassini from 9-17 November 2005. See also a colourised (and larger) version of this sequence at Ciclops, or in gif form at spaceplasma.
Tethys and Saturn’s rings, photographed by Cassini, 12 April 2005. Also visible at the end, just outside the rings on the right, is Janus.
