Have Aliens Replied to Our Message from 1974?
Are these intricate crop patterns which materialized nearby Chilbolton (UK) radio telescope a reply to a message sent 40 years ago from Arecibo? Judging by the decoded messages this is exactly what they are.
In 1974 a message was sent from Arecibo radio telescope. The message consisted of 1679 binary digits (ca. 210 bytes) and was transmitted at frequency of 2380 MHz. It was modulated by shifting the frequency by 10 Hz, with a power of 1000 kW. The “ones” and “zeros” were transmitted by frequency shifting at the rate of 10 bits per second. The total broadcast was less than three minutes.The message was written by Dr. Frank Drake (creator of the Drake equation) with help from Carl Sagan (and others). The message consists of seven parts that encode the following (from the top down):
– The numbers one (1) to ten (10)
– The atomic numbers of the elements hydrogen, carbon, nitrogen, oxygen, and phosphorus, which make up deoxyribonucleic acid (DNA)
– The formulas for the sugars and bases in the nucleotides of DNA
– The number of nucleotides in DNA, and a graphic of the double helix structure of DNA
– A graphic figure of a human, the dimension (physical height) of an average man, and the human population of Earth
– A graphic of the Solar System
– A graphic of the Arecibo radio telescope and the dimension (the physical diameter) of the transmitting antenna dish
Because it will take 25,000 years for the message to reach its intended destination of stars (and an additional 25,000 years 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. In fact, the stars of M13, that the message was aimed at, will no longer be in that location when the message arrives. According to the Cornell News press release of November 12, 1999, the real purpose of the message was not to make contact, but to demonstrate the capabilities of newly installed equipment.
Yet in 2001 something strange happened. In the morning of August 14 an unusual crop pattern appeared on a field near the then Britain’s largest radiotelescope in Chilbolton, Hampshire. It was different from any other crop circle that had appeared before. It did not look much like anything from the ground level and in broad daylight, but in the evening, when setting sun lay shadows on the crops, a meticulously crafted image came up with an image resembling a portrait of a head. This was only the beginning, however, since the true shock came three days later when the “face” was joined by something that looked like a data strip.
