Crop Circle Response 2001

In 1974 Carl Sagan sent a message into space in the form of radio waves beamed into space.  It was the most powerful broadcast ever deliberately beamed into space and was directed at a star cluster nearly 25,000 light years away.  The message consisted of a picture depicting our planets location in our solar system, our mathematical system, a simple shape of our body, an example of our DNA double helix structure, and a crude drawing of how we broadcast the message.
