NASA’s Terra satellite has been orbiting for ten years, taking measurements of the earth with many sensors. People say, “A picture is worth a thousand words,” and these satellite images definitely fit the description. Right now, my house is in the snowy region of the Northeastern US. Looking at this image gives me a sense of sympathy for all the other folks in the wintry, snowy parts of the northern hemisphere — and it shows me where they are!
