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.

Wallpaper: Tethys and Saturn

Wallpaper: Tethys and Saturn
The moon Tethys is pictured drifting across Saturn’s disc. Tethys is one of 3 medium sized moons (including Rhea and Dione) which are largely composed of ice with small amounts of rock and whose features consist mostly of craters. Tethys does have two outstanding features which are a huge 400km impact crater whose diameter is about 2/5 that of Tethys itself, as well as a giant 2000km valley that stretches across 3/4 of Tethys diameter.

IMAGE NOTE: This image was not altered other than extending Saturn’s rings to fill the page on the upper right side. The original image was in square format so the subtle ring outlines were more cropped than seen here.
