The North American Astrophysical Observatory (NAAPO) is a not-for-profit organization dedicated to the advancement of the field of radio astronomy. Started as part of an effort to save the Ohio Sate University "Big Ear" Radio Observatory (OSURO), NAAPO directs a number of on-going efforts including the development of a revolutionary, omni-directional radio telescope (Argus) and spreading the word about the Flag of Earth.
Unfortunately, it isn't. The "Big Ear" radio telescope was destroyed by land developers in 1998 in favor of a golf course and housing complex. When it stood, however, it was an impressive structure located just off of State Route 23 in Delaware, Ohio.
Argus is a next-generation, omni-directional radio telescope in prototype-development as part of a NAAPO initiative. Traditionally, radio telescopes have a very narrow range. For an experiment, take a sheet of paper and, with a pencil, poke a hole in the middle of it. Take the paper outside and look through the hole at the night sky. What you see through the hole very closely resembles what a typical, ground-based radio telescope can "see". Now, take the paper away. Now, you're seeing what Argus can see! You can learn more about Argus and how it works at argus.naapo.org.
The Flag of Earth is a flag designed in 1970 by the late James Cadle. Cadle was inspired to create a flag that represents all of humanity and not just a division of nationality. The flag shows the earth as a blue disc (as it appears from space). It also shows a yellow disc to represent the sun and a white disc to represent the moon. Learn more from our Flag of Earth website.
NAAPO is a private volunteer organization and is not affiliated with the SETI Institute. SETI is something that almost anyone with proper equipment and education can do! SETI is not a trademark, and there are many independent SETI efforts in various stages of development.
