what is that? Yeah we know that picture is flag of our planet, Earth. So, not only our country that had a flag, but also our planet. Are you waiting any visitors in your home now? From your family in Yupiter maybe? or from Andromeda galaxy? 





I am curious, if NASA have met aliens and invite them to dinner, and made the flag for earth so aliens won't get lost in their way to our planet
