Forty-four years have passed since the first human attempt to communicate with potential space objects, through a message called the "Aricepo message", which was launched in space to find who receives and knows our way.
On 16 November 1974, the radio telescope in Puerto Rico launched a series of radio waves containing the equivalent of 210 bytes of data sent to a nearby group of stars called the M13.
The group is 22,000 light years away, meaning that the message will take the same time to reach this group. On the other hand, it is not entirely known.
The letter was designed by a number of scientists, including Frank Drake and Carl Sagan, a digital message that was sent over three minutes.
In theory, scientists believe that those who receive the message from space objects can decode it.
If they do, they will find some information about humanity and what we know about our role in the universe.
The letter contains numbers 1 to 10, the atomic numbers of elements in nature, including hydrogen and carbon, and the basic formulations of DNA.
It also contains a symbol for an average person, the number of people on earth (4 billion at the time), a map of our solar system, and a sketch of the wireless Aricepo telescope that sent the message and its location.
However, as the message reaches its target, the star group will move away, meaning that the message will not reach anyone.
But who knows? The universe is full of things we know very little about. The real purpose of the message was to demonstrate the power of the Arecibo radio telescope.
"The event was purely symbolic, to show we could do it," said Donald Campbell of Cornell University, who worked at the Observatoire Observatory at the time, on the 25th anniversary of the event in 1999.
However, it is good to know that there is a 3-minute vault of humanity making its way across galaxies. Arisibu's message was an inspiration to humanity and a source of hope that there would be others in the vast space.
And perhaps another object in a remote place in the universe has sent his own "Arecepua" message and is currently on our way.
If you have the opportunity to write a message to our anonymous neighbors in the universe, what will their content be?
