Interstellar exploration is a completely new field for human beings, and human exploration of extraterrestrial life is becoming more and more in-depth, and some astronomers have even begun to study the problem of "interstellar migration".
In this exploration, an exoplanet called "Gliezer 581g" is known as the "second Earth" because of its existence, there is a 99.9% chance that life exists.
However, this statement has also caused some controversy, and Michel Didarod, a professor of astronomy at Princeton University in Switzerland, who is the "first person in astronomy", believes that "Gliese 581g" does not exist at all.
It is precisely because of this controversy that human beings have encountered difficulties and challenges in the process of exploring the universe, but scientists are also constantly actively exploring and learning from others' strengths.
So does Glazer 581g exist?
How much does it resemble the Earth?
Who can give this "super-earth" such a high degree of survivability?
1. Glitzer 581g was discovered.
In 2009, astronomers at the University of California, Santa Cruz, discovered a red dwarf star called "Gliese 581" in Gemini, about 20 light-years from Earth.
And this star is not the first exoplanet to be discovered, because it was discovered as early as 2005, only 0.04 AU away from "Gliezer 581", this exoplanet is very close to "Gliezer 581", so it is called "Gliezer 581b".
At the same time, "Gliezer 581b" is also the closest exoplanet to the Earth discovered by mankind, and is known as a "hot ocean planet".
However, with the rapid development of science and technology, more exoplanets began to be discovered, and "Glazer 581g" was discovered at this time.
During the observations at that time, scientists found that in the habitable zone of "Gliezer 581", an exoplanet appeared and was named "Gliese 581g", which was thought to be the possibility of life.
Later, astronomers from the University of Pennsylvania in the United States used the telescope of the Pacific Observatory to observe and verify it, and confirmed that "Gliezer 581g" is in the habitable zone of "Gliezer 581", so it is believed that there is a high probability of life, and it is called "second earth".
However, in these observations, scientists also found a problem, that is, "Gliezer 581g" has not been repeatedly observed, but only through a single phenomenon, it is concluded that the probability of life is 99.9%.
This phenomenon is known as the "optical pitot" phenomenon, which is an extreme "orange flare" phenomenon that is almost impossible on the surface of the sun, and the only way humans can detect this phenomenon is through large telescopes.
At the time of the discovery of the "optical pito" phenomenon, astronomers discovered the existence of exoplanets in "Gliezer 581", and "Gliese 581g" happened to be in the habitable zone, so there is a high probability of life.
However, in 2014, NASA observed and verified the "Gliezer 581G" again, but did not find the "Gliezer 581G", so it was suspected that there was a deviation.
2. The controversy over the existence of Gliezer 581g.
The existence of Gliezer 581g has also caused speculation among astronomers and scientists in other countries, such as those in Canada and Switzerland, who have doubted the U.S. statement.
Several astronomers at the University of Geneva in Switzerland and the University of Toronto in Canada believe that the United States wants to dominate this field, so it deliberately exaggerates and exaggerates the existence of exoplanets.
And Michel Didarode, a professor of astronomy at Princeton University in Switzerland, even directly said that this "Gliese 581g" is simply nonsense, and there is obviously no "Gliese 581g".
However, American astronomers believe that Michel Didarod only wants to deny the existence of the exoplanet "Gliezer 581g" in order to prove his authority.
Astronomers at the University of Pennsylvania at NASA also disagree with these claims, arguing that "Glazer 581g" exists, but due to the limitations of human technology, it cannot be observed and verified.
3. The existence of Gliese 581g.
It wasn't until 2018 that NASA observed "Gliezer 581" again, but found the figure of "Gliezer 581G", and the results of this detection were quite accurate and secure, but it only indirectly proved the possibility of the existence of "Gliezer 581G".
Therefore, astronomers at the University of Pennsylvania have expressed their opinions, and astronomers at the University of Pennsylvania in the United States believe that science and technology cannot develop forever, even if it can continue to advance.
Because of the current scientific and technological limitations of human beings, it is not possible to directly observe and verify the "Gliezer 581g", so it can only be through indirect methods, so this also leads to the fact that the "Gliezer 581g" has not been confirmed definitively.
But he also thinks that Gliezer 581g exists, but there is a misjudgment, and this misjudgment is not an accidental phenomenon, but a frequent occurrence.
Therefore, astronomers at the University of Pennsylvania believe that the exoplanet "Gliezer 581g" should be carefully considered, and he believes that "Glitzer 581g" has a gravitational interference, which has led to the misjudgment of astronomers, so this series of lists should be removed from the system.
4. The truth about the Gliese system.
The Gliese galaxy is a red dwarf star, which is also very small compared to the Sun, it is only 1/3 to 1/4 the size of the Sun, so its brightness is also very faint compared to the Sun, only 1% of the Sun.
Therefore, it is also necessary for astronomers to observe and verify it through large telescopes.
And the two exoplanets, "Gliezer 581g" and "Gliezer 581d", are both in the habitable zone of "Gliezer 581", so there is a high probability of life, also known as the "second Earth", the relative distance of these two exoplanets is also very close, and there may be gravitational interference between them, which will also lead to misjudgment by astronomers.
That's why astronomers at the University of Pennsylvania will say what he thinks, but with the continuous development of human science and technology, mankind is also expected to make detailed observations and verification of the Gliese galaxy through large telescopes.
V. Conclusion
Interstellar exploration is a very curious way of exploration, but also a challenge to human beings themselves, human beings are born curious animals, always full of curiosity about the unknown, and never satisfied with existing knowledge.
Therefore, human exploration of the universe is endless, and we cannot be sure whether the exoplanet "Gliese 581g" exists, but our debate and exploration of it are also worthy of recognition.
Even if Gliezer 581g is ultimately proven to be non-existent, the process is still memorable, because this controversy and discussion has also promoted the research and progress of scientists on extraterrestrial life and exoplanets.
This is also a driving force for progress, and astronomers at the University of Pennsylvania are also in continuous research and exploration, for the sake of truth, for this spirit is also worthy of our admiration and respect.
So does the Gliezer 581g really exist?
We may not have the answer, but with the advancement of technology, we will also hopefully uncover the truth of all this.
