Where are you on Earth Right Now? Thats the question NASA posed the public on Earth Day recently. The twist? NASA wanted you to answer, not with words, but with a selfie. 36,422 of you replied with images that were then stitched together to form the mosaic you see above. To fully enjoy the image, theres an interactive 3.2-gigapixel version that lets you get up close and personal with all the submissions (or, if you participated, try to find yourself).
