Tuesday, April 22, 2014, is Earth Day. In celebration of the planet, NASA is inviting everyone on the biosphere to take a #GlobalSelfie.
To participate, people are encouraged to take ‘selfies’ and share them on social media using the hashtag #GlobalSelfie. Twitter, Instagram, Facebook and Flickr can all be used.
NASA says it will then use the images to create a “mosaic image of Earth" to be released in May.
What's a #GlobalSelfie? The following is from the NASA website:
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.
