Breaking the Ice

Here’s a look at the frozen crater Cilix, a rare ice-filled dent in the scoured and resurfaced face of Europa. Taken by the Galileo spacecraft in 1998, this image has been reassembled from raw data and color-calibrated by Gordan Ugarkovic to highlight the surface detail of this fascinating frozen cueball of a moon. Covered by…

An Icy Crescent

A color-composite image of Saturn’s moon Enceladus, assembled from RGB raw image data recorded by Cassini on July 4, 2010. The moon’s heavily textured and highly-reflective icy terrain is nicely accentuated by the low angle of sunlight. The Cassini spacecraft was over 104,000 miles from Enceladus when the images were taken. Image: NASA/JPL/SSI. Edited by…

Ice World

662-mile-wide Tethys, as seen by Cassini on March 3, 2010. Part of the 1200-mile-long Ithaca Chasma can be seen on its western edge, running north to south. With a density .97 times that of liquid water, Tethys is almost completely made of ice. Image has been adjusted to bring out surface details. Image: NASA/JPL/Space Science…

Jet Setter

The icy Enceladus shows off its southern geysers, stately hovering in orbit around Saturn in this raw image from the Cassini spacecraft, taken on Christmas day. It is impressive to get such a clear view of the geysers with the low phase angle of the sunlight. Typically the geysers are only seen when the sun…

Ice Volcanoes on Titan?

This infrared image, taken by Cassini during a March 27, 2009 flyby of Titan, shows a bright area of topography called “Hotei Arcus” that is believed to be active with volcanoes that ooze slushy ice rather than molten rock. Over the past four years, this area has undergone variations in brightness that indicate resurfacing activity of…
