JACKSONVILLE, Fla. - NASA is asking everyone on the planet to take part in a worldwide celebration of Earth Day this year by taking selfies.
According to 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 they are trying to create an image of Earth from the ground up while also fostering a collection of portraits of the people of Earth.
IMAGES: #GlobalSelfie at Channel 4
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.
If you want to participate in NASA's Earth Day #GlobalSelfie campaign, go here to visit the NASA website and download the Global Selfie sign. Simply print it out, write where you are from in the open space, and take a selfie with it. Then, upload the photo to any of their event pages on Facebook, Flickr or Google +, or to your own social media sites using the hashtag #GlobalSelfie.
