On 16 November 1974.human tried to send a message to space more accurately to the globular cluster nebula M13 in Hercules constellation. The message was called the ARECIBO-Message because it was sent on the ceremony to mark the remodeling of the Arecibo radio telescope in Puerto Rico
The message consists of seven parts that encode the following (from the top down):
The numbers one (1) to ten (10) (white)
The atomic numbers of the elements hydrogen, carbon, nitrogen, oxygen, and phosphorus, which make up deoxyribonucleic acid (DNA) (purple)
The formulas for the sugars and bases in the nucleotides of DNA (green)
The number of nucleotides in DNA, and a graphic of the double helix structure of DNA (white & blue)
A graphic figure of a human, the dimension (physical height) of an average man, and the human population of Earth (red, white, & blue, respectively)
A graphic of the Solar System indicating which of the planets the message is coming from (yellow)
A graphic of the Arecibo radio telescope and the dimension (the physical diameter) of the transmitting antenna dish (purple, white, & blue)
Because it will take 25,000 years for the message to reach its intended destination (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 core of M13, to which the message was aimed, will no longer be in that location when the message arrives. However, as the proper motion of M13 is small, the message will still arrive near the center of the cluster. 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.

I think that sending all those informations maybe wast of time and energy, it was a sort that scientist search for there ego they looking to geek aliens, they looking for some creater on the image of scientist, even commun human can’t understand those information how it’s supposed that alien do ?
Scientist suppose that they will find aliens like them , clever brilliant and like the complicated informations, but it would be much more easier and even reliable if they just sent Hello word with all languages.
