In 1974, a powerful broadcast was beamed into space from the Arecibo Radio Telescope, Puerto Rico. The transmission consisted of a simple pictorial message aimed at 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.

This was a very powerful emission, equivalent to a 20 trillion watt omni directional broadcast using Arecibo’s megawatt transmitter attached to its 305 meter antenna, concentrating the beam in a very narrow funnel of the sky. The emission, that could be detectable just about anywhere in the galaxy within that funnel, would have been detectable by a receiver similar in size to Arecibo’s. This transmission was the strongest man-made signal ever sent.

The message consisted of 1679 bits, arranged into 73 lines of 23 characters per line. The “ones” and “zeroes” were transmitted by frequency shifting at the rate of 10 bits per second and was transmitted at a frequency of 2380 MHz and modulated by shifting the frequency by 10 Hz. The total broadcast was less than three minutes.

This was the pictorial message sent…

The most interesting portion was the one that represented humanity.

The element in the center represents a human.

The element on the right depicts the size of the
Human population in 1974, around 4.2 billion.

Chilbolton Face: August 13, 2001

A week before the Chilbolton Code formation appeared, an eerie face image appeared in the field, not far from where the Code was to appear. From ground level it looked like an undecipherable mess. The image was created almost like a newspaper photograph, with dots in various sizes giving an impression of depth when viewed from a distance.

When a helicopter passed overhead, the image became perceivable. It is an odd image, vaguely reminiscent of the infamous Face on Mars. If the bottom of the Chilbolton Code refers to the 1999 formation for more detail, the center of the Code, where one can see what appears to be a arge-headed humanoid, may refer to the near-by face image for more detail. If this is the case, then the senders of the message sent along a snap shot.

Notice the resemblance?

The Reply

It is so named because it appears to be a response to the Arecibo message that appeared in a farmland next to the Chilbolton radio telescope, home of SETI in Hampshire, UK, on 19 August 2001. It was 75 feet wide and 120 feet long.

Now let’s take a look at this ‘reply’ which had taken 27 years from the time it was transmitted. This is shown as an animated image of the first transmission, slowly transposed with the ‘ET’ response. Note the slight difference in the shape of the heads!

The reply had a few differences. Two that stand out are:

For one, the humanoid has a far larger head. There is now an extra strand on the right side of the DNA double-helix and another, less obvious, change is in the binary coding of the number of nucleotides in DNA itself (in the center).

The human genome has 4,293,917,614, or nearly 4.3 billion nucleotide sequences, while the mystery genome sequence has 4,294,966,190, or 1,048,576 (one million) more nucleotide sequences than human DNA.

Red Setter, a world expert on DNA research, has made a very interesting observation that he made only after intensive personal research stimulated by the odd DNA images in the Chilbolton Code formation. He notes that:
“The central part of the Chilbolton pictogram shows that a DNA double helix as found on Earth, with 10 base pairs per turn, has been replaced on one side by a novel single-stranded helix with just 6 bases per turn.

I had to work hard for several days, to discover that the single-stranded helix with 6 bases per turn refers to 2′, 5′-linked RNA or DNA, as opposed to the normal 3′, 5′ variety. This is known to hardly any molecular biologist, and I found out only by making an accurate model”.

Is it a prank played by hoaxers? Or is it an actual response from an ET civilization?

Consider this…

Why should ‘they’ have responded with a message in a crop field? Why not through radio like we had done? Probably they don’t want to shock us with the ultimate truth that we are not alone, just yet. Is it part of a graduated disclosure response?

Is it because ‘they’ wanted to publicize it, for all to see, considering the secrecy in such matters? Perhaps, just like SETI, we weren’t ready to listen as a people. Alternatively, they may have been trying to communicate for years, but the self-serving official cover-up has kept a lid on the pertinent information.

Is it possible that someone in that area was knowledgeable about Drake’s Arecibo signal who could have contributed information to the (human) circle makers to construct this elaborate hoax to entertain us? Whoever made them had enough scientific knowledge to be able to subtly alter the binary code so that the formation answered some of the questions that were asked. Why would a human being with this degree of scientific capability waste his or her time making fake crop circles?

Was it possible for pranksters to have made this within visual range of the security assets that surround the Chilbolton facility?

SETI’s Response:
There is no evidence to suggest an other-than-earthly origin for these graphics. In other words, a prank by a group of ‘circle makers’, but of which we have not a clue, even seven years on!! Can the makers come forward and show us how it’s been done over one night and put to rest once and for all the mystery at Chilbolton?
