At 5:31pm on August 1st 1997, a radio message was received at the
ERSO Radio Observatory, coming from Arcturus. The signal received
appears to be of intelligent origin, rather than a natural phenomenon.
The signal is binary in nature, consisting of an amplitude-modulated
(AM) carrier wave containing a tone that oscillates between two
frequencies. 16129 distinct bits were recorded (tone high = 1,
tone low = 0), then there was a pause 68 seconds long before the
next "page" began. During this pause, the carrier wave was still
present, though the amplitude-modulation ceased (the tone was silent).
Several distinct pages were received in this manner, and then the
whole process simply repeated, and continues to repeat to this day.
(if you are interested in hearing how they sound, you can
download a program to play the messages
through your internal PC speaker, and it now includes the sourcecode)
Each page has been stored in a simple text file, with each bit represented as an ASCII character ("0" or "1"), in the order they were received, 60 characters per line (arbitrary number chosen, 60 fits in most text viewers).
Your goal is to try to decode these messages. You may use whatever resources you have at your disposal, including but not limited to books on cryptography, physics, astronomy, and radio. Discuss it with your friends, or with your enemies for that matter! You may also find that writing computer programs can be helpful too, parcitularly for formatting the message properly. Do whatever it takes to decode the messages and extract what information you can.
Hint for getting started: A message is much easier to read when you know how to view it correctly first.
Think you have the answer? necrobones at necrobones dot com, and tell me what you've found! Don't ask for hints though, that's what the rest of the world is for... :-)
6/19/98: I have created a new message board for the Arcturus Project, and for any other "SETI-Games", hence the name of the board: The SETI-Games Message Board. I encourage everyone to discuss this project, and create their own SETI-games and discuss them as well. Please don't be discouraged if activity on the message board is slow at first. If everyone participates, we'll all have a lot of fun!

Fiction. This "message from the stars" was created as a "game", the idea is to see just how easily a message can be decoded when it contains symbols and syntax that are unfamiliar, particularly when the message is intended to be easy to decode.
If the aliens start sending new messages, or transmit any revisions, they will be made available under new version numbers.
