New Delhi: NASA has released a 3.2 gigapixel Global Selfie of the entire Earth on Earth Day. The selfie is created from 36,000 selfies that people shared on social networking sites. Earth Day is an annual event, celebrated on April 22, on which events are held worldwide to demonstrate support for environmental protection. Users can zoom the 3.2-gigapixel image to look at individual photos. The "global selfie" mosaic was built using more than 36,000 individual photographs drawn from the more than 50,000 images tagged #GlobalSelfie and posted on or around Earth Day, April 22, on Twitter, Instagram, Facebook, Google+ and Flickr. Selfies were posted by people on every continent and 113 countries and regions, from Antarctica to Yemen, Greenland to Guatemala, and Pakistan to Peru. The `global selfie` was assembled after several weeks of collecting and curating the submitted images, NASA reported. (With Agency inputs)
