The 3.2 gigapixel Global Selfie mosaic, hosted by GigaPan, was made with 36,422 individual images that were posted to social media sites on or around Earth Day. NASA asked people around the world to answer a question “Where are you on Earth Right Now?” 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. People on every continent – 113 countries and regions in all – posted selfies.
