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: Ganymede Up Close

Two views of Ganymede’s patchwork surface taken by Galileo around 1997. While some areas appear geologically older (as demonstrated by the record of impact cratering) some seemingly younger areas recall the fracturous features seen at Europa. Many theorize, just as they do at Europa, that there may be a global ocean of water beneath the surface at Ganymede. However, it is also assumed (if if this does exist) that this ocean would be more shallow and under a much thicker crust of rock hard ice than that of Europa.
