Tuesday is Earth Day and NASA is asking everyone to take part in a special event to mark the occasion.
NASA’s #GlobalSelfie event aims to create a mosaic image of Earth made up of portraits of people submitted over social media.
NASA plans to follow five social media sites: Twitter, Instagram, Facebook, Google+ and Flickr.
You just need to get outside, take a picture of yourself, and let NASA know where you are! Then, upload the picture to one of the sites and use the hashtag #GlobalSelfie.
