The message composed by Dr. Frank Drake, Carl Sagan, and different scientists, was conveyed utilizing frequency modulated radio waves, changing it into a 3 minute binary transmission consisting of roughly 210 bytes.
The transmission produced a picture and when decoded, the message gives the next data:
Numbers from 1 to 10
The atomic numbers of the weather that type deoxyribonucleic acid (DNA)
The formulation for the sugars and bases within the nucleotides of DNA
The variety of nucleotides in DNA, and the double helix construction
A human determine, the bodily dimensions of a median man, and the human inhabitants of Earth
A illustration of the Photo voltaic System
A graphic of the Arecibo radio telescope and the size of the transmitting antenna dish
The sign was 1,000,000 instances stronger than the everyday TV transmission.
27 years later in 2001, we did obtain a response!
On August 21, 2001 two crop circles popped up close to the Chilbolton Observatory in Hampshire, UK.
One resembled a human face however the different has since dubbed the “Arecibo Reply,” because it accommodates a format almost an identical to the unique 1974 transmission, albeit with a couple of adjustments.
Crop circle: “Arecibo Reply”
The response, when decoded, leaves us with a number of variations.
Most curiously, nonetheless, is one other message encoded inside a crop circle (generally known as the Crabwood formation) that appeared in 2002, additionally in Hampshire, UK. This specific crop circle accommodates the picture of an extraterrestrial together with a circle, or disc, containing one more binary message. The message decoded utilizing 8-bit binary ASCII code.
