Signal from the potentially inhabited planet Gliese 581d

Scientists have recorded a signal from the planet Gliese 581d and have already stated that the conditions on it are suitable for the birth and maintenance of life. At the moment it is known that the celestial body is twice as large as the Earth. Signals have been fixed for a long time, but only in 2014 it was possible to notice that they are repeated, they are cyclical. No phenomenon in the universe is capable of this, unless, of course, it is not created artificially.

Signals indicate the presence of extraterrestrial civilization on the planet, trying to transmit a message to neighboring systems and galaxies. But the "letter" has not yet been deciphered.

About the planet

Gliese 581d is an exoplanet in the system with the same name (Gliese 581). At the moment, its existence is not exactly defined, but everything indicates that it really exists. The planet is located in the constellation Libra, and pretty close to our solar system. Before it - only 20 light years.

If you believe the information received in September 2010, the considered planet in its system is on the fifth place from the star (Earth - on the third, after Venus and Mercury). Many scientists call it "Super Earth", because it has dimensions that exceed the globe by a factor of 2. And its mass is 6-8 times larger.

For the first time the message that a potentially inhabited exoplanet was discovered was received from Switzerland on April 24 in 2007. Together with Gliese 581d, Gliese 581c was also fixed. The discovery belongs to several astrologers, whose actions were supervised by Stefan Udri.

Scientists are still arguing about the reality of the planet, but skeptics have always met in space exploration.

Detection process

If you believe the data of British experts, their team of astronomers caught a message from the planet Gliese 581d. When the information is confirmed, disputes and discussions about the existence of the celestial body will be finally discontinued. Now there are many opinions on this matter, beginning with the reality of the planet and ending with physical anomalies, which capture terrestrial technology.

At first there was only one way to discover the celestial bodies. They are viewed in powerful telescopes when they pass in front of their star. This technology was used by American scientists in 2014.

But their British colleagues expressed doubts about the relevance of the method. With its help you can find only gas giants, like our Jupiter. They themselves used more modern technologies that confirmed the location and reality of the planet.

It is now known that Gliese 581d is supposedly a potentially inhabited planet in the system of the same red dwarf. The distance to it is 20 light years.

Characteristic Signal

When scientists first recorded a signal from the planet Gliese 581d, they did not attach much importance to it. Then the existence of herself was under a big question, many discussions were held on this subject. Some astronomers still consider signals as a mere manifestation of stellar activity, but high, otherwise they would not be able to reach the solar system.

In 2014, American scientists repeatedly checked the characteristics of the received signal. They did not find any evidence that he was being artificially given. Astronomers suggest that it is a consequence of light and magnetic radiations spread by a red dwarf. At the intersection, they meet, creating a special cosmic noise that they could not catch earlier.

March 7 this year it became known that the signal from the potentially inhabited planet Gliese 581d is not a consequence of cosmic noise. It repeats every few months, has a similar cycle.

Skeptical debate

After the report on the discovery of the planet was received, the data was rechecked using HARPS. But the discovery of Swiss scientists was not confirmed. Russian astronomers have also made attempts to find the heavenly body through their technologies until 2012. Then scientist Roman Baluev expressed doubts about his reality.

In 2014, attempts to confirm the existence of Gliese 581d were undertaken by astronomers at the University of Pennsylvania. There were calculations that refuted the information of Stefan Udri. According to them, the recorded phenomena are only a consequence of stellar activity.

In early spring 2015, the refutation of data on Gliese 581d was questioned. British scientists have explored methods for discovering planets of American astronomers. They spoke about the fact that these methods are far from perfect and do not meet modern requirements.

Thus, if the planet Gliese 581d itself is questioned, the signal from it also does not exist. At least today there is no clear evidence of its reality.

As for the signal, the skeptics point to light and magnetic radiation. When they intertwine, they can produce characteristic sounds that a person mistakenly mistook for an extraterrestrial message. Its cyclicity is actually absent. The signal changes, but very slowly, like everything that happens in the universe (relative to people's lives).

Hypotheses and simulations

Despite disagreements with astronomers from many countries, British scientists believe in the existence of the planet Gliese 581d. Moreover, they insist that the signals are a certain algorithm of encrypted symbols. Those in aggregate are a message for neighboring systems and galaxies.

Astronomers from Britain are sure that if they use not only high-tech equipment, but also modern methods of research, then it will be possible to separate the signal itself from interference. After that, you can try to decipher it. Perhaps the civilization from the Gliese system is also trying to find its brothers in the mind.

Thanks to numerous computer simulations it was possible to establish that on the considered planet there are water oceans. There is also an atmosphere and clouds with precipitation in the corresponding zone. And as it was already reported earlier, life was necessary for water to be created. Consequently, Gliese is suitable for all parameters for habitat. It is located in a favorable zone relative to its luminary, it has water, and clouds with precipitation indicate its circulation.

Signal data

No one can tell exactly when the first signal was sent from the planet Gliese 581d. Initially, it was not taken seriously, because then the heavenly body itself was not found. Later, after the first talks about him, more attention was paid to the reality of the planet, and not to the message.

Until the spring of 2015, it was believed that the signal is an ordinary cosmic noise. Similar sound waves were already caught by earthly equipment, and repeatedly.

Now astronomers claim that the signal repeats with a small interval. It is full of noise, but attempts are being made to clear the message. Ultimately, scientists plan to decipher signals from a potentially inhabited planet.

Communication with extraterrestrial civilizations

If it happens that Gliese 581d really turns out to be a real planet with its population, then humanity needs to be more careful in trying to start a dialogue with it. Scientist Stephen Hawking has repeatedly urged people to beware of communication with extraterrestrial civilizations.

He argues his statement by saying that the resources of any celestial body that has something similar to the globe are limited. They can stop. And then the inhabitants will have nothing else but to look for a similar planet to use it as a source of resources.

Conclusion

Despite the abundance of debates and skeptical discussions around the planet Gliese 581d, many scientists, as well as all the people of the Earth, would very much like it to be inhabited. Then humanity will have the opportunity to exchange experience and knowledge, breakthroughs in technology, medicine, programming.

In the end, all people would like to go on a journey beyond the solar system. And the planet Gliese 581d is great for the final destination. It remains only to agree on a visit with its population. Perhaps, it will be possible to do this if scientists still decipher the received signal.
