* NASA is paritcipating in Earth Day this year with the agency's #GlobalSelfie event, asking people to take a photo of themselves outside and post it to social media using the hashtag #GlobalSelfie. NASA will use the images to create a mosaic image of Earth -- a new "Blue Marble" built bit by bit with your photos. Get more info on how to participate here.
What's a #GlobalSelfie?
NASA astronauts brought home the first ever images of the whole planet from space. Now NASA satellites capture new images of Earth every second. For Earth Day we are trying to create an image of Earth from the ground up while also fostering a collection of portraits of the people of Earth. Once those pictures stream around the world on Earth Day, the individual pictures tagged #GlobalSelfie will be used to create a mosaic image of Earth -- a new "Blue Marble" built bit by bit with your photos.Need an idea of what kind of picture to take? Get outside and show us mountains, parks, the sky, rivers, lakes -- wherever you are, there's your picture. Tell us where you are in a sign, words written in the sand, spelled out with rocks -- or by using the printable signs we've created that are available here.
Post your #GlobalSelfie on Twitter, Instagram, Facebook, Google+ or Flickr.
