today doodle of Google Reminds something from … a third party contact, and it is because it is dedicated to "Arecymbo Message". What exactly is this "message"?
It is a radio signal emitted from the Arejibo Observatory in 1974 and contains basic information about humanity and planet Earth in coded form. The purpose of the show was to communicate with another extraterrestrial civilization that would receive and decrypt the message. The message is sent in the direction of the area called Heracle's spherical clusters at a distance of 25,000 light years.
The transmission of the message, referred to as the relevant entry on Wikipedia, was only once as part of the celebration of telescope renovation at the Arejimbo Observatory on November 16, 1974.
The message consists of 1,679 bits (210 bytes), which were transmitted at a frequency of 2 880 MHz with a frequency modulation at 10 Hz transmission power of 1000 kW. The numbers of 1 and 0, of which the message is in their binary format, was transmitted with a frequency shift at a rate of 10 digits per second. The total shipment lasted for 3 minutes.
But since it will take 25,000 years to reach its destination (and another 25,000 years for a possible response), Isisi's message was more a demonstration of human technology than a real attempt to start a conversation with foreigners. In fact, the M13 stars targeting the message is no longer in this position when the message comes, but the message will still reach the middle of the galaxy cluster.
The message was created by Frank Drew, in collaboration with Carl Sagan and others. There are 7 sections in the message from top to bottom:
– Number 1 to 10 (white boxes)
Atoms of hydrogen, carbon, nitrogen, oxygen and phosphorus. These elements are DNA components (purple squares)
-Matematical formulas for sugars and bases in DNA nucleotides (green squares)
-Set of nucleotides in DNA and representation of the DNA double strand structure (white and blue)
-Graphic representation of a human being, in an average human dimension (height) and the human population of the earth (red, blue / white and white squares)
-Graphic display of the solar system indicating which planet the message is from (yellow)
-Graphic representation of the Areizum observatory and the dimensions of the emitting radio (purple, white and blue).
