NASA invited people from all over the world to take a "selfie" and share it with the world on social media for Earth Day this year, ABC News reported.

Unveiling the 2.3 billion-pixel sized "global selfie" on Thursday, the mosaic showed more than 36,000 pictures of people and places around the world in commemoration of Earth Day, the U.S. space agency said.

After more than 50,000 images tagged #GlobalSelfie were uploaded to social media sites like Facebook, Twitter, Instagram, Google and Flickr on April 22, 36,000 individual selfies were used.

Users on every continent and 113 countries or regions - including Antarctica, Yemen and Peru - joined in. According to IBN Live, after weeks of collecting and curating more than 50,000 submissions, the so-called "global selfie" was released.

The 3.2-gigapixel zoomable mosaic shows tens of thousands of selected pictures arranged to look like Earth as it appeared to the Suomi National Polar-orbiting Partnership climate satellite orbiting the planet on Earth Day.

"With the Global Selfie, NASA used crowd-sourced digital imagery to illustrate a different aspect of Earth than has been measured from satellites for decades: a mosaic of faces from around the globe," said Peg Luce, deputy director of the Earth Science Division in the Science Mission Directorate at NASA Headquarters in Washington.

Designed to increase environmental awareness and knowledge of the agency's work, the project will help protect our home planet.

"We were overwhelmed to see people participate from so many countries," she said. "We're very grateful that people took the time to celebrate our home planet together, and we look forward to everyone doing their part to be good stewards of our precious Earth."

With five more missions to gather data on the planet which are slated to launch this year, NASA has 17 Earth-observing satellites in orbit, NASA said.
