Messages from Evpatoria

In early 1998, we were monitoring the net for simulated SETI messages. Those activities involved the decoding of fictional ET messages. There were a few games where people sent message and others tried to decode them,

Later on that same year, we learned that the company Team Encounter wanted to celebrate the New Year by sending an interstellar message. They were asking for volunteers to help them write a message to the stars. We proposed our help tas proof-readers of the messages. After a brief exchange of emails, we ended-up leading the project and writing the message itself. It took nearly six months to research, develop and write the message. We were doing it during week-ends and after work. Special computer software were built to generated, test and write the alphabet and the text itself.

1999

The message sent in 1999 is a series of small pictures of 127 by 127 pixels. Each page contains symbols conveying the information. The whole message starts by describing mathematical concepts and symbols. In the the following pages notions such of physics, chemistry and biology are introduced and used to present more information about us. The message is more than merely a juxtaposition of scientific symbols put on a page. It described concepts and knowledge that can only be achieved through a great deal of understanding the nature surrounding us. For example, the periodic table of atoms do more then just saying we know those atoms. It states that we understand the fundamental structure of matter. Knowledge of Science is like a tree. Knowledge of a small branch implies that the big one is well understood.

At the end of the message, we invite the Extra-Terrestrial reader to send a reply. After explaining what we are and what we know, we ask the same questions and hope for a reply.

The 1999 message was sent by the Evpatoria Installation on May 24th, 1999 to those stars:

All these targets are single star, except HD186408 (aka 16 Cygnus A) which is a wide binary. The companion, 16 Cygnus B, has a Gaseous Giant orbiting it. They are in a region of the Milky Way that is nearly perfect for our needs. In that direction, the noise degradation of the signal carrier will be minimal. Furthermore, there are others interesting targets beyond those stars.

2003

The 2003 message is an improvement over the 1999. It is no longer divided into 23 pages but rather into a very long page. The message can be download as a bitmap or an image. The message was sent by the Evpatoria Installation on July 6th (from 02:00 to 07:39) and by Roswell, New Mexico on the same day (05:00 to 10:39 MST).
