Scientists believe that although there is no extraordinary life in the solar system, it is likely to find out -of -the -earth life in the outer planet (planets other than the solar system), and they are full of expectations for the Weber telescope.
Chris Yingpe, a professor of astronomy at the University of Arizona and Daniel Ape, a professor of planet science, believes that due to the Weber telescope (later referred to as "Weber"), he can get the spectral data of the exterior planet atmosphere, which can analyze the characteristics of these atmosphere. Perhaps perhaps maybe Can quickly discover signs of life outside life.
Observing the on -earth planet atmosphere is just the sideline of the Weber telescope
Weber telescope has been developed for 25 years and spent $ 10 billion. It is one of the most expensive and most advanced space telescopes in history. The main task of this telescope is very high, that is, I hope to see the starting point of the Big Bang, which is the universe of 13.8 billion light years.
Scientific observations and research have obtained the most important evidence of the Big Bang ~ Cosmic microwave background radiation, which is considered to be the ember of the first ray of light from the Big Bang, and the initial state residue of the universe bang. The Weber telescope will investigate this ray of light and restore the initial state of the Big Bang.
Therefore, the Weber telescope is equipped with highly sensitive infrared sensors, spectrals, etc. The biggest difference from the Hubble telescope is to observe the infrared band in the infrared band that is longer than the visible light. Because the infrared rays can penetrate the dust of the universe, and the main mirror diameter is the 2.7 times that the Hubble telescope (later referred to as "Hubble"), The lighting area is 6.5 times that of Hubble, so Weber's observation ability is 100 times that of Hubble.
How powerful is this ability? Some metaphors can clearly identify a coin 40 kilometers away. Of course, this metaphor is not very rigorous. If Weberbi Hubble is 100 times stronger, can Hubble only see a 400 -meter coin?
After the launch of Weber has been impacted 6 times in the space, the last time it was considered to be beyond the designs to endure the impact expectations, people are worried that they will affect observation and images. However, the images released in July 12, Beijing time are still amazing. It is compared with Hubble's extreme deep space viewing field, referred to as Hubble's deep field pictures, and the gap is established.
It is said that a small sky area placed on the fingertip arm of the fingertips, and Weber photographed thousands of galaxies. The farthest galaxy was 13.5 billion light years from us; The shot of the sky is much less, and the sharpness is not a magnitude at all. (See the picture above)
This makes many astronomers happy, and more the mystery of the universe will be revealed. No wonder the president of the United States could not wait for the original release time, and a press conference was held one day in advance. The releases that were released a lot higher than Hubble made everyone hang down, and more than $ 10 billion was thrown away in vain.
The pictures posted were just the Weber trials, and the observation of God has not yet begun. The observation is just a part of the planet, but this glance is really shocking, but it has captured the planet's atmosphere, indicating that through analyzing the atmosphere of the planet, it is obtained whether there is a life existence in that planet!
How do astronomers look for foreign planets?
Since the beginning of the new era of aerospace in the last century, scientists have always hoped to find outdated life or even outside civilization. When humans still cannot see nearby planets, they used to have many fantasies, such as Venus and Mars with some clues observed.
In fact, as early as in ancient times, people had fantasized the closest planet from us ~ there was life on the moon. In ancient China, the beauty Chang'e lived in the Guanghan Palace of the moon. In the last century, the unmanned detection and manned moon landing activity of the moon caused the myths that had been circulating for thousands of years. The moon not only had no one, but did not even have the atmosphere, and the hair of a life did not exist.
So people's eyes turned to the closest Venus and Mars. Through telescopes, they could see Venus's dense atmosphere, and Mars has a web -like gully. So people speculate that there are Venus on Venus, there are Mars on Mars, and those gully on Mars are artificial engineering built by Mars. From the perspective of scale, they can make such a huge artificial project. The degree of civilization there is much stronger than humans.
With the subsequent planet detection activities, these fantasies were shattered one by one. Not only did Venus and Mars not find life, but on the planets, dwarf planets, or satellites of the entire solar system, no evidence of life was found, but scientists We did not give up, and still tirelessly found the planets such as Tuwei Liu, Muwei II, and Mars who thought it might have life.
But one thing seems to have become the consensus of the scientific community long ago, that is, the solar system cannot have high -level lives. Even if those planets really have life, they are extremely low -level bacteria. So scientists have long turned their attention to the solar system and began to search for out -of -the -planet on a large scale.
After decades of hard work, through the development of a series of increasingly advanced telescopes, more than 5,000 outer planets have been found. These discoveries prove that a fact is generally accompanied by planets. But is there any life or civilization on these planets? There are no valuable clues until now.
But so far, the so -called "discovery" is not truly "seeing" or seeing those planets, to say, most of them are just "feeling" that there is a planet where there are planets there. This is because the universe where human observation ability is relatively vast is still too small. Even the most powerful telescope cannot see the nearest stars from us. Tens of thousands or even tens to millions of planets. Now use telescope to observe whether there is an outer planet around a star. The main method used is called Lingxing Method, also called the hidden star method. It is when a planet is sandwiched in the middle of the stars' sight, this star will have a shielding phenomenon, that is, a little change will occur, and it will be periodically presented.
Through this phenomenon of light and through some other auxiliary methods, scientists can roughly determine whether this is a planet, and calculate how the planet is quality, how far from the star and how long the rotation cycle is. Then through the view of the speed method, micro -attractive lens method, etc., mainly through the Doppler effects and gravity laws, and the data of the planets through the movement of the planet and the stars. Essence
Among more than 5,000 planets, there are also very few observations observed through direct imaging methods, but these so -called "imaging" is also a fuzzy light spot that uses pixel sizes. Generally, it is still to capture through non -visible light such as infrared spectrum. These directly observed planets have now exceed 100, all of which are huge gaseous planets, most of which are dozens of times larger than Jupiter's quality.
In this way, what exactly the planets that have been discovered are, and whether there are signs of life on it, it is even more guessing.
So how does Weber determine whether there is life on the external planet?
Weber telescope is the strongest telescope with the strongest observation capabilities so far. You can see a coin 40 kilometers away. But the universe is too vast. Even the nearest stars from our nearest stars, the distance between the 4.3 light -year distance, if it is reduced to a coin, the distance is far more than 40 kilometers, and it is quite a few thousand kilometers thousands of kilometers.
Therefore, it is necessary to see that a planet is still only extravagant. However, Weber had some of his own skills. Just opened his eyes and glanced, he captured a atmospheric spectrum of more than 1,000 light years. In fact, before that, Weber's old predecessor Hubble had analyzed many exotic atmosphere, and in 2013 received a clear signal of a planet with water.
However, the signals observed by Hubble are still very vague and the amount of information is very small. Weber is based on the observation of HBB and further sits on these evidence.
WASP-96B is a giant giant star that has long been discovered from our 1150 light years. Its quality is about half of Jupiter, which is larger than Jupiter. It is 1.2 times that of Jupiter. The planet is very close to its own sun (star), only about 6.43 million kilometers, but Mercury is about one -nine -fi of the sun, and the transfer cycle is only about 3 and a half Earth days.
Weber was observed for 6.4 hours of observing WASP-96B, and measured the light changes and transmission spectrum of light from the planet 0.6 ~ 2.8 microns band light with near infrared, which revealed some of the previous hidden in the atmosphere. Details, that is, significant water characteristics, signs of haze, and evidence of clouds, these observations are not sure or even think they do not exist.
In fact, Weber did not see what the planet looked like, but through the observation of infrared bands, the spectrum data in the atmosphere could be obtained. The researchers could analyze these spectrums and know what components of the planet's atmosphere consists of the atmosphere. What about their respective abundance (content ratio).
Life planets and planet atmospheric components without life have different characteristics. Some elements can only occur only when life is metabolized. These ingredients related to life will be shown in the atmosphere. This is the transformation of life. The atmosphere will show the characteristics of life, such as oxygen and methane in the atmosphere.
Plants and algae on the earth, due to the photosyntine and other pigments of photosynthesis, will capture the light of a certain wavelength, thereby changing the color of the atmosphere. Weber can sensitively capture these different colors of spectrum through sensitive infrared cameras. The discovery of the planet marks the spectrum of chlorophyll existence, which indicates a typical evidence of life existence.
Of course, planets like WASP-96B are unlikely to exist. Weber only practiced this time and gave scientists a good sign. Among the more than 5,000 outer planets that have been discovered now, about 4%of the planets of life that are likely to exist, that is, there are more than 200, of which the so -called livable planet is not far from the star. There are dozens of planets with liquid water. These are the focus of Weber's future observation.
For example, TRAPPIST -E-only 39 light years is a planet similar to the earth. In the next few months, Weber will take the camera to it. Trappist-1 is a red dwarf with a spectral type M. Its planet system is a very meaningful special system. There are at least 7 planets, 3 of which are in the so-called livable belt!
Therefore, observing this planet system will likely find the existence of life!As a result, scientists are full of hope.If you really discover extraterrestrial life, it will be a huge breakthrough that human beings know the universe and life. Scientific research will enter a brand new era. This is a great temptation for scientists who are constantly pursuing new discoveries.what.Therefore, the Weber telescope opened his eyes in the distant deep space to see the universe. It has epoch -making significance. The entire scientific community is paying attention to its new discoveries every day.What do you think of this?Welcome to discuss, thank you for reading.
