(KTVI) – Time to take some pictures! NASA is holding a global selfie event for Earth Day.
Here’s how it works: you snap a photo of yourself then post it on one of five social media websites, including Twitter, using a hashtag of #globalselfie.
NASA will then use those photos to create a mosaic image of Earth.
You can also post your photos on Instagram, Facebook, Google+ and Flickr.
