This App of the Day will let you see Earth like you've never seen it before. NASA released an app called Earth As Art. It offers stunning pictures of Earth from five different satellites orbiting the planet. The satellites can measure light outside of what we can see, so each image has all kinds of colors that are usually invisible to the naked eye. The app also includes several time lapses of locations across the globe that have undergone massive changes in the past few decades. Earth As Art is a free app, but it is currently only available on the iPad.
