Only a few days after Google published satellite photographs of possibly secret nuclear facilities in Iran, new images of obviously manmade structures have been spotted in the Gobi desert in China. All of the structures are located in northwestern China, near the borders of Xinjiang and Gansu province. This is an area that China uses for its military, space and nuclear programs.
In this Google Map image, burnt-out vehicles can be see seen in what is speculated to be a military training facility. Northwest of that site can be seen an additional manmade facility. Another image reveals what appear to be large manmade bodies of water. This radial structure may be a targeting site.
A number of severe thunderstorms have swept through the SE US recently. Some storms generated tornadoes that were truly devastating. The news channels have many photos of the ground destruction. We can see the path of the storms in satellite images. Here is a link to one of those images.
A comparison of 250-meter resolution image from a NASA MODIS instrument at 0.65 µm and 0.87 µm visible channel images centered on Tuscaloosa, Alabama on 28 April 2011 showed signatures of a few of the larger and longer tornado damage paths from the historic tornado outbreak (SPC storm reports) that occurred on 27 April 2011. The yellow arrows point to some of the paths.
Here is a link to an animation between the two channels

The Central Intelligence Agency does have a bunch of high-powered satellites and other "classified" instruments, so it's possible they've been using them to eavesdrop on my conversations with friends about possible sci-fi movie plots.
What's more likely: they figured out on their own that intelligence-gathering instruments could be really helpful to scientists, who can read detailed pictures of melting sea ice, growing desserts and other phenomena to better understand how climate is changing the planet.
The C.I.A. recently confirmed that it had revived this controversial data-sharing program known as Madea, which stands for Measurements of Earth Data for Environmental Analysis. If you decode that C.I.A. code name, it means that government spies are working with climate scientists to gather images and data about environmental change, as well as its impact on human populations.
Not everyone is convinced that climate change is a real threat to national security, and so some complainers are complaining that this collaboration between scientists and the C.I.A. is a misuse of resources, but what do they know?
Really? What do they know? So much of what happens over at C.I.A. headquarters is top-secret.
Maybe the whole thing doesn't sound that action packed, but I'm telling you, if you had the right actors playing the scientists, it could be a blockbuster. And if you have the right scientists analyzing the data, it might provide really valuable insights into global environmental change.

Researchers using NASA satellite photos to look at their bases in Antarctica found something odd with the photos: large red streaks in otherwise colorless sea ice areas. Causing the strange coloration is emperor penguin poop. It's a huge discovery among the penguin researching crowd as they've had a hard time locating the breeding grounds of these penguins.
Since the emperors spend several months on the ice during their winter breeding season, the poop accumulates so much that it can be seen from space. And it's no ordinary poop. It's high in salt and high in odor, making it very undesirable to be around for humans. One researcher said he's lost a dozen pair of boots to salt damage caused by the penguin poop.
From the vantage point of space, scientists have been able to pinpoint 38 emperor penguin breeding areas, including the appearance of 10 new breeding site and disappearance of six old sites from the previous land-based mapping effort. All in all, it's good news for the emperor penguin population, which was thought to be in crisis because of diminishing ice surfaces around the edges of Antarctica.
Still skeptical about this? Here's a video report that shows what we're talking about here.
NASA's Earth Observatory is celebrating its 10th anniversary this year and in that time is has given scientist and the general pubic a new view on the earth and how it is changing. The Earth Observatory site has satellite images of events on the earth ranging from storms and climate change to the growth of cities. The images are not only interesting to look at but they have helped scientist research the changing of seasons, snow caps, and cloud patterns in a whole new way. With growing popularity the images are also being sought out by other agencies, for example when the coast of Louisiana was hit by a hurricane the images were used to get a clearer picture of the flooding in the cities. Check out their archives, you will see awesome pictures and learn something new about the planet we live on.
