On Earth Day, NASA asked people all over the world to take selfies and send them the pictures for a special project.
NASA's “Global Selfie” that included more than 36,000 individual photographs from more than 50,000 images. The project was designed to encourage environmental awareness and to recognize NASA's ongoing work to protect the earth.
According to Peg Luce, deputy director of the Earth Science Division in the Science Mission Directorate at NASA Headquarters, NASA used crowd-sourced digital imagery to illustrate a different aspect of Earth than had been measured from satellites.
The selfies were posted by people from 113 countries, resulting a global mosaic 3.2-gigapixel image that users could scan and explore to look at individual photos.
