This first page of the Cosmic Call 1999 message, shown above, involves only numbers Cosmic Call Physicists are announcing today that they have designed a message to be broadcast in the direction of nearby stars in order to search for extra-terrestrial intelligence. This project is being presented by Dr. Yvan Dutil and Stephane Dumas from the Defence Research Establishment Valcartier, near Quebec City (Canada), to the American Astronomical Society meeting in Austin, TX. This is the first time in a quarter of a century that such a cosmic call will be attempted.   The complete message is about 400,000 bits long and will be transmitted three times over a 3-hour period in the direction of the four selected stars. Then, it will be followed by a series of greetings from people around the world. The transmission will start on March 15 1999. Finding a transmitter for this task was not easy; the project will use a 70 m (230 ft) Ukrainian antenna equipped with a 150 kW transmitter b...

The Arecibo Message In 1974, the most powerful broadcast ever deliberately beamed into space was made from Puerto Rico. The broadcast formed part of the ceremonies held to mark a major upgrade to the Arecibo Radio Telescope. The transmission consisted of a simple, pictorial message, aimed at our putative cosmic companions in the globular star cluster M13. This cluster is roughly 21,000 light-years from us, near the edge of the Milky Way galaxy, and contains approximately a third of a million stars. The broadcast was particularly powerful because it used Arecibo's megawatt transmitter attached to its 305 meter antenna. The latter concentrates the transmitter energy by beaming it into a very small patch of sky. The emission was equivalent to a 20 trillion watt omnidirectional broadcast, and would be detectable by a SETI experiment just about anywhere in the galaxy, assuming a receiving antenna similar in size to Arecibo's. The message consists of 1679 bits, ar...

  Voyager probes Launched in 1977, the Voyager probes carried two golden records that were inscribed with diagrams depicting the human form, our solar system and its location. Also included were recordings of pictures and sounds from Earth. Wikipedia Pioneers 10 and 11, which preceded Voyager, both carried small metal plaques identifying their time and place of origin for the benefit of any other spacefarers that might find them in the distant future. With this example before them, NASA placed a more ambitious message aboard Voyager 1 and 2-a kind of time capsule, intended to communicate a story of our world to extraterrestrials. The Voyager message is carried by a phonograph record-a 12-inch gold-plated copper disk containing sounds and images selected to portray the ...

  Pioneer plaque The Pioneer plaques are a pair of gold - anodized aluminium plaques which were placed on board the 1972 Pioneer 10 and 1973 Pioneer 11 spacecraft , featuring a pictorial message , in case either Pioneer 10 or 11 are intercepted by extraterrestrial life . The plaques show the nude figures of a human male and female along with several symbols that are designed to provide information about the origin of the spacecraft. [1] The Pioneer spacecraft were the first human-built objects to leave the solar system . The plaques were attached to the spacecraft's antenna support struts in a position that would shield them from erosion by stellar dust .

  "Lingua Cosmica." A language for extraterrestrial communication developed by Hans Freudenthal, Professor of Mathematics at the University of Utrecht. Details of it are presented in Freudenthal's book 1 published in the Netherlands in 1960. LINCOS represents an extension of the logistic language of mathematics developed by Alfred North Whitehead and Bertrand Russell. It is intended to be conveyed by unmodulated radio signals of varying duration and wavelength which represent phonemes. The signals would be combined to make up concepts or words. Lancelot Hogben, who himself described a code for communication with alien intelligence, called Astraglossa , discussed Freudenthal's work. The Internet Encyclopedia of Sciemce Chapter III: Behaviour 3 00 1. For the time being it would be premature to try to describe  human behaviour by a system of general rules like the mathematical  and chronometric rule...

Lincos : Design of a Language for Cosmic Intercourse , published in 1960 by Hans Freudenthal , expands upon Astraglossa to create a general-purpose language derived from basic mathematics and logic symbols. A new generation Lincos has been developed since 2000 by Alexander Ollongren, as a part of the more general Astrolinguistics .   Wikipedia Lincos consists of a variety of mathematical terms and phrases, to be encoded into specific combinations of radio pulses and signal shapes and then beamed out into space. It is devised purely in terms of semantics and human logic, and accomplishes understanding by building from simple beginnings. Statements are arranged in words, sentences, and paragraphs. Freudenthal’s program begins by establishing the meaning of the terms "plus" and "equals." He would, for instance, send signals something like "beep bloop beep tweet beep beep" (1 + 1 = 2), perhaps followed by "beep bloop beep beep...

An early radioglyph scheme for interstellar communication (see CETI ) proposed by the British mathematician Lancelot Hogben . He gave details of it in a 1952 lecture to the British Interplanetary Society , entitled "Astraglossa, or First Step in Celestial Syntax," and later described it in a book. 1 Hogben suggested that numbers be represented as ordinary pulses (e.g. five pulses for the number five) and mathematical concepts, such as "plus,""minus," or "equal," each by a distinctive signal – a radioglyph.
