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.

Ceres: The Center of Occator Crater

We missed this amazing image (March of 2016) of the enigmatic Occator Crater on Ceres by the Dawn spacecraft. Scientists studying Ceres’ bright spots determined the spots’ age are only about four million years, some 30 million years younger than Occator crater itself. This suggests that there have been eruptive outbursts of sub-surface salt-water on Ceres over a long period of time and could even still be happening today.

That is an amazing discovery considering that the size of Ceres is smaller than anyone would have expected to have the ability to generate internal heating enough to create such processes.
