Nasa celebrates Earth Day with the ‘global selfie’

This mosaic was made from 36,422 selfies. You all look beautiful.

The internet loves a selfie – you know it, we know it and Ellen DeGeneres definitely knows it. Now, Nasa knows it too, creating a mosaic of the planet Earth out of 36,422 selfies from around the world.

Unveiled yesterday in celebration of Earth Day, NASA created the ‘global selfie’ by asking its fans to send in their portraits via social media. Over 50,000 submissions were received from 113 countries, all tagged with their location via Facebook, Twitter, Instagram, Flickr and Google+.

The selected images were then transformed into a single 3.2-gigapixel image, hosted by GigaPan.

What can I do with it?

Well, nothing – but viewers are able to pan and interact with the mosaic, zooming into a single selfie or pulling back and taking in the view.

The images is based on views of each hemisphere that were captured on April 22, 2014 by Nasa satellites. Scientists from the space agency have helped identify thousands of new planets in recent years, but Nasa studies no planet more closely than our own. There are currently 17 Earth-observing satellites in orbit, helping researchers piece together a clearer picture of our atmosphere, land and ocean.

Of course, if you get bored staring at the global selfie mosaic – you could always watch the video instead.
