World in selfies 


On Earth Day this year, NASA asked people all around the world a question: "Where are you on Earth Right Now?"

To answer this question people were asked to post their selfie on social media. 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 the space.The 3.2 gigapixel "Global Selfie", was made the with 36,422 individual images.
