What if the Earth was made of selfies?
NASA asked earthlings to send in their selfies on Earth Day this year, hoping to use a picture as a pixel and to create a mosaic image that would like the Earth from space.
NASA released the photo this week, which consisted of 36,422 individual photos that were posted on social media and tagged #globalselfie on or around April 22, 2014.
People from 113 countries took part, spanning from Antarctica to Yemen, Greenland to Guatemala.
