You need to upgrade your Flash Player The theme of this blog is not only and obviously space, but in particular “terrestrial worlds”, places that tend to have surfaces on which one could walk or at least attach oneself to. These places sometimes also have other earth-like familiar features such as atmospheres, weather, volcanos, geysers and perhaps, we are finding, even exotic oceans, rivers or lakes that are not necessarily made of familiar materials we are used to here at home. The second theme is imagery. Occasionally I do some retouching of images when needed if an image is incomplete or sometimes “dirty” or noisy. I will attempt to correct image shortcomings based upon other images or well-accepted presumed attributes. When this is done, notes will be offered as to what was added, why and sometimes how it was done. This way no one should ever wonder if something they are looking at is real or photoshop.

Rhea Transits Saturn

These images were taken of Rhea as it (and Cassini) sped across Saturn’s globe on August 30, 2007. The near-natural color images were composed from raw near-infrared, green and ultraviolet filtered files made available on the NASA-Cassini website. Some of the details may have been enhanced through the use of infrared and ultraviolet in place of red and blue… but they have been adjusted to reflect what we assume is closer to actual natural color.

Rhea in Transit 01From approximately 93,823 km.

Rhea in Transit 02From approximately 78,967 km.

Rhea in Transit 03From approximately 53,788 km.
