New images up on Photojournal.
In order left to right: original crop, light decon, darkened w/ decon. The smallest spots appear to be resolved but also really fuzzy still? Whats up with that? Strange effect at bottom edge of large spot as well. Sorta looks like CCD bloom but I don't know that I've ever seen a situation where it was so small and also right next to another bloom, without them both merging. And here, we have 4 of them... Just to throw an idea out there: Impact at a location with near surface water, creating the typical central peak in the crater but with an increase localized heating and pressure in the subsurface water. Water ejects through the peak in a one time eruption, blowing out the side like Mt. St. Helens, scattering salty-icy debris to the right. Sublimation has left the salts behind to slowly decay. Doesn't solve for why we don't see other larger chunks nearby though. -------------------- |
