	Arecibo Message
		The first attempt at CETI; it consisted of a message beamed toward the star cluster M13 (the Great Cluster in Hercules) on November 16, 1974, by the Arecibo radio telescope.
		A technique first suggested by Frank Drake (see Drake's cryptogram) was used to encode the message which consisted of a string of 1679 binary digits, or bits.
		An intelligent being striving to decipher the message, it is hoped, would eventually recognize that 1679 is a multiple of two prime numbers, 23 and 73 (see mathematics, as a universal language).

	Arecibo message - Wikipedia, the free encyclopedia
		The Arecibo message is a radio message that was beamed into space at a ceremony to mark the remodeling of the Arecibo radio telescope in 1974.
		A crop circle about the Arecibo Message was found near Chilbolton's Observatory, depicting a similar message (allegedly from greys-type aliens) that included silicon in their biochemistry and other subtle changes in the data, like the three inhabitated planets of their native system.
		This corresponds to the horizontally written binary 14 multiplied with the wavelength of the message (126 mm).

	25th anniversary of Arecibo radio message to E.T.
		The message was sent during the dedication of a major upgrade to the Arecibo radio telescope on the afternoon of Nov. 16, 1974, and contained some very basic information about the human race.
		Arecibo Observatory is operated by the National Astronomy and Ionosphere Center, managed by Cornell for the National Science Foundation.
		The real purpose of the message was to call attention to the tremendous power of the radar transmitter newly installed at Arecibo and the ability of the telescope's 1,000-foot diameter dish antenna to project a powerful signal into space.

	Arecibo, Puerto Rico - Wikipedia, the free encyclopedia
		Arecibo was officially founded as a city by the Spanish crown in 1616, under the governorship of Captain Felipe de Beaumont y Navarra, when the King of Spain granted the land (and the Tainos living there) to Lope Conchillos.
		Arecibo is also known as the Villa del Capitán Correa after the Puerto Rican hero Captain Antonio de los Reyes Correa, who as a member of the Spanish Army defended Arecibo from a British invasion led by Admiral Whelstone in August 5, 1702.
		Arecibo is located on the north coast of the island of Puerto Rico, about 80 kilometres (50 miles) west of San Juan, or approximately a 1-hour trip by car.

	Crop Circle Research: The Chilbolton 'Arecibo message' Formation
		Arecibo is on the northern coast of Puerto Rico and contains a natural disc-shaped hole in the rock.
		The message was actually transmitted on November 16th 1974 and consisted of 1679 pulses of binary code (0's and 1's) - which took a little under three minutes to transmit.
		Lastly, what was representative of the Arecibo transmitter in the original message is even more cryptic and would imply a diagrammatic version of the formation which appeared in the same field at Chilbolton last year, in 2000.

	Arecibo message Information
		The Arecibo message is a radio message that was beamed into space at a ceremony to mark the remodeling of the Arecibo radio telescope in 1974.
		Because it will take 25,000 years for the message to reach its intended destination of stars (and an additional 25,000 for any reply), the Arecibo message was more a demonstration of human technological achievement than a real attempt to enter into a conversation with extraterrestrials.
		A crop circle containing a modified form of the Arecibo message was found near Chilbolton's Observatory, depicting a grey in place of the human figure.

	Answer To 'Arecibo' Crop Circle? - A Clever Hoax?
		The Arecibo Radio Telescope broadcast the signal on November 16, 1974 during a ceremony marking an upgrade of the Puerto Rico-based telescope.
		The message was encoded in Primes in an extremely logical manner, and thus Bill Hamiltons suggestion that aliens wouldn't be able to decode it insults both the intelligence of the scientists who went into making the original Arecibo message and the intelligence of any potential alien presence reading it.
		I don't know whether the Arecibo-response message is a hoax or not, perhaps some analysis of the bend in the stems of the bent crops (and whether there is breakage as is common with obvious hoax circles) could yeild some answers.

	Improving The Arecibo Message
		The Arecibo Interstellar Message (AIM), sent in the direction of the globular cluster M13 in 1974, was the most significant attempt to deliberately establish communication with extraterrestrial civilizations.
		We would hope for this message to prove effective the first time it is intercepted; if the odds favor us long enough for another civilization to actually receive the message, the worst thing that could happen would be for them to ignore it or to be unable to decipher it.
		Correct translation of a message requires the correct interpretive framework, and the correct translation of the AIM requires one to alter that interpretive framework several times—surely a barrier to communication.

		The message they sent was only the second serious attempt to actively signal civilizations around other stars; the first was in 1974 by the founder of the SETI Institute Frank Drake (also known for Drake's equation).
		The main drawback of the Arecibo message is its lack of resistance to the noise.

		Neither message got a response, which probably isn't surprising, given the fact that Venus'; atmosphere consists primarily of carbon dioxide with clouds of sulfuric acid and a mean surface temperature of 867 degrees Fahrenheit.
		After Arecibo, scientists returned to the idea of physical messages, attaching 12-inch gold-plated copper phonograph disks to the probes Voyager 1 and 2, both launched in 1977 and both ultimately destined for interstellar space.
		The message consisted of 1,271 ones and zeros (or bits) and was based on the key that 1,271 is the product of two prime numbers, 31 and 41.

	Arecibo Message
		The Arecibo Message being referred to was sent to Messier 13, a globular star cluster in the constellation of Hercules, on November 16, 1974, from the Arecibo Radio Observatory in Puerto Rico.
		As M13 is 24,000 light years from Earth, and radio signals travel at the speed of light, it will take 24,000 years for the message to reach the star cluster.

		The second is a modified version of a message that was sent out into deep space in 1974 from the Arecibo satellite dish in Puerto Rico, broadcast in the direction of the globular cluster M13 in November of that year.
		The Arecibo message, which was designed by Frank Drake (who was then Director of the Arecibo Observatory in Puerto Rico, and who went onto become Chairman of the Board of the SETI Institute) together with his Observatory staff, was a simple graphic consisting of 73 rows of 23 "bits" per row.
		The message was sent by simple shifting of the signal between two frequencies in the 2,380 MHz band.

		The most interesting experiment in 1974 with Arecibo however was it's 3 Terawatt narrowband transmission of a "human template" in the direction of the M13 globular star cluster which consists of 300,000 stars and is in the constellation of Hercules.
		The unexpected coorelation between Einstein and Arecibo in 1974 is evident as a Nobel prize was awarded due to Arecibo discovery of the Puslar in a "Binary system" and the astronomers helping to prove his Theory of General Releativity.
		The Arecibo Human Template message was transmitted on November 16th, 1974 and consisted of 1,679 pulses of binary code (0's and 1's).

		The broadcast was particularly powerful because it used Arecibo's megawatt transmitter attached to its 305 meter antenna.
		The message consists of 1679 bits, arranged into 73 lines of 23 characters per line (these are both prime numbers, and may help the aliens decode the message).
		It consists, among other things, of the Arecibo telescope, our solar system, DNA, a stick figure of a human, and some of the biochemicals of earthly life.

	Self-Decoding Messages
		The signal would be acknowledged by virtually all observers to be a message transmitted by intelligent extraterrestrials.
		The message was transmitted by modulating the transmission with two different frequencies, precisely as low-speed telephone modems do, with the data being sent at a rate of 10 bits per second.
		Before it was transmitted toward M13, the author of the message, Frank Drake, first beamed it on paper to Carl Sagan over lunch at the faculty club at Cornell University.

		The next set of binary bits in the message is the atomic numbers for five of the most common and abundant elements that make up all life as we know it: hydrogen, carbon, nitrogen, oxygen, and phosphorus.
		The astronomers decided to aim the message at a large and close collection of stars that were available at the time of day and place during the dedication ceremony.
