We built the app to provide information and images taken by Nasa's satellite through live challenge between users. Questions about images will be raised upon users playing. These questions could be answer within 3 seconds. An article about the image with original source will be pop up once users finish the play. We hope, through this app, users may find an encouragement to get information about how our homeland, earth, looks from space.

This project is solving the Where on Earth challenge.


Sway with space. Together we challenge
