The Flag of Earth
The Flag of Earth flew for many years at the OSU Radio Observatory while it was in operation. The Flag of Earth also flies at many other SETI locations around the world, and at many radio and optical observatories whether or not a program of SETI is carried out. It symbolizes the fact that SETI is carried out on behalf of Humanity as a whole. The individual people, organizations, and nations involved are unimportant compared to the overall efforts of Humanity that have collectively made this search for their brethren possible.
The yellow part of the flag represents the sun, the blue circle symbolizes the Earth, and the small white circle represents the Moon.
James (Jim) Cadle, the designer and maker of the Flag of Earth, sold not only flags of various sizes but also decals and lapel pins (also suitable as tie tacks).
