Cadle's Flag of the Earth
October 27, 2008 2:12 PM Subscribe
The Flag of Earth is often flown at locations doing SETI work in order to indicate that the search is the "work of humanity and not a specific country or organization." The creator of this flag of the Earth (there are others) James W. Cadle died in 2004, but he left the design in the public domain. The flag is now supported by the North American Astrophysical Observatory.
