Earth in 2012: Seen from Space

NASA offers a look back on our planet in the last year from space; the views include true color satellite images, Earth science data visualizations, time lapses from the International Space Station, and computer models. While these images are striking, they also unveil a massive crack across a glacier in Antarctica, active fires across the United States, the growing area of the ozone hole, and the strength of Hurricane Sandy's winds.
