On Earth Day this year, NASA asked people all around the world a simple question - "Where are you on Earth Right Now?"We asked people to answer the question on social media, with a selfie. The goal was to use each picture as a pixel in the creation of a "Global Selfie" - a mosaic image that would look like Earth appeared from space on Earth Day. The mosaic was made with 36,422 individual images that were posted to social media sites on or around Earth Day, April 22, 2014.
