Put the planet in perspective this Earth Day with these mesmerizing images from NASA satellites.
In honor of Earth Day, rather than bombarding you with eco-friendly lifestyle gadgets and accessories, or assuaging your enviro-guilt with "how to green your life" tips (though we have those too!), I'm going to ask simply that you click through these mesmerizing images posted and sent along by our friends at at the NASA Goddard Space Flight Center.
All photos and images are courtesy of the Landsat program at NASA Goddard Space Flight Center. Since 1972, Landsat has been capturing valuable—and beautiful—images of our planet from far above.
