I am always amazed with satellite images. I have seen lots of them in the last years, since my job has to do with Geographical Information Systems, and stellite images are one of the main source for GIS data. It never stopped pleasing me looking at the beautiful images that earth obeserving satellites as LandSat, Terra's Aster/Modis, and other produce.
One of such imager is this one from Uvs Nuur Basin in Mongolia. I have signed to the RSS feed from Earth Observatory site, and every week I am pleased to see some of the most interesting views of our planet. Once I see a nice image, I go to one of the best sites I know, and try to see if there are more interesting views around, just before trying a flyover using Google Earth.
For the lake cited above, I saw in Google Maps that there are other lakes, even more interesting than the first. Both of them can be seen in the map below (teh lake from above's site is the one on the left on the map below):
I strongly advise anyone to sign Earth Observatory's RSS feed. Not only for the images they provide, bat also becase it's a great source of information regarding the small marble that we live on.
