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.

Search for Earth Sized Planets: Begin

Sunday, March 8th, 2009

Its not that we haven’t been trying, but for all our effort… the best we have found lurking among the stars comparable to our home is a planet at about 5x Earth sizes. When you consider the advances and methods of detection, one can almost assume that Earth-like extra planet discoveries will be made from ground-based observations very soon. With this week’s successful Kepler launch, the assumption may be that (if they are out there) we might be talking about finding many Earth-like planets beyond our Solar System fairly soon. Hopefully, the job of finding extra-solar planets is about to get really interesting.

Click the image for a hi-res to see the banner on the side (or here). I like how home-made it seems, “Search for Earth Sized Planets”. Makes it almost seem like a boy-scouts rocket project.

Visual Online Solar System

Simple yet informative online model of the solar system. I knew Jupiter had over 60 moons, but you don’t really visualize that until you see a model in action (seen above). The thing that really becomes clear is how many minor moons orbit WELL beyond the orbits of the major moons of the outer planets. It also provides models of some of the more well-known extrasolar planetary systems to the extent of bodies that we are currently aware of.
