The Flag of Earth symbolizes the Earth (the center blue disk), the Sun (the yellow disk on the left), and the Moon (the white disk on the right). The Earth and its most important celestial neighbors – the Sun and Moon – are overlaid on a backdrop of the darkness of space.
The Flag of Earth website is administered by NAAPO – the North American Astrophysical Observatory. NAAPO is a not-for-profit organization formed to run the Big Ear Radio Observatory in Delaware, Ohio, and which now runs the Ohio Argus Array.
