Alien call? Astronomers suspect radio signals from exoplanets

Although we already have a series of very excellent observation machines and equipment, such as the "China Sky Eye" FAST, the Hubble Space Telescope, and the huge telescopes in Europe that have been basically constructed, and the LeBron James Webb Space Telescope, everyone may be forced to recognize it. The ability of astronomical observation work is really outdated.

Even though scientists have already discovered more than 4,300 exoplanets, there are only a handful of planets that can really be visualized immediately. At a distance of hundreds of millions of light-years or even hundreds or thousands of light-years, scientists can only use some current methods to carry out scientific research on such long stars, and many of the results obtained still need to be repeatedly scrutinized and confirmed. .

In the short term, it seems that everyone still does not have the ability to greatly improve the ability to observe and work. Therefore, speculation and inference about the natural environment of exoplanets still need a lot of new research ideas to help everyone restore the real world based on the only information. exoplanet worlds, and assist in the discovery of a large amount of potentially useful information content in the observed data information.

Recently, scientists have sorted out the wireless communication data signals from this long star for the first time in the data information of exoplanet observation. Said to open a new door.

The first thing to point out is that the wireless communication data signals mentioned here are not the type of electromagnetic waves that intelligent creatures use to communicate with each other, but just radio waves that are naturally caused. Even so, biologists are still excited, because it is a new and upgraded scientific research that can improve our understanding of this exoplanet to a very large level.

"Observations sent by meteoric wireless communications of planets are the most promising results of exoplanet magnetic fields," University of Pennsylvania scientist Jake Turner and his friends detailed in their senior thesis published in Astronomy & Astrophysics. The way detection is carried out, expertise in these areas can provide valuable insights into the inner structure of a planet, the free flow of air and the beauty of the environment."

In their graduation thesis, they explained in detail this kind of research ideas for exoplanets-

We know that in addition to carrying out nuclear reactions at key points, the planet will continue to release a lot of higher-energy plasma technology, which is the planetary wind. When this planetary wind travels through outer space, it will encounter the magnetic field of the planet and produce a strong impact. During this whole process, the rate transition of the high-energy particles is detected by biologists in the form of electromagnetic waves, which is statistically known as "bursty" (bursty data information).

This kind of situation often occurs above the atmosphere. Our geomagnetic field is changing the direction and speed of the solar wind in the whole process, which will also cause a strange "sound" to be monitored by our equipment. Similar to it, similar situations will also occur in the sky of other planets in the solar system with magnetic fields. Everyone has reason to believe that even an exoplanet, as long as it has a magnetic field, will have a similar practical effect, which has been tested by everyone.

The difference is that this data signal is slightly further away. And in the case of inspection, biologists must find a way to remove the noise from the earth and other stars, so that we can hear the sound that everyone wants.

This is where Turner's elite team has been working diligently. In recent years, they have developed and designed a production line process called ''BOREALIS'' to remove this noise. In the initial case, they did experiments on Jupiter, using some data and information from Jupiter's exploration, and then measured what this wireless communication would look like in a longer-term area.

After completing the detection of basic wireless communication data signals on several planets, the scientific research elite team also contacted such wireless communication data signals to exoplanets. Earlier this year, the International Low Frequency Array Space Telescope (LOFAR) in Spain discovered abnormal electromagnetic waves when observing a red dwarf star named GJ 1151, which scientists could not describe. The elite scientific research team believes that this may be caused by the planetary wind when the magnetic field of a likely Earth-sized planet collides with each other.

On this issue, scientists also have to confirm with radio observations after the fact. However, the scientific research elite team firmly believes that their research ideas are correct and can be used in the scientific research of exoplanets. So they used LOFAR again to make observations of three systems that had already been identified as having exoplanets: 55 Cancri, Upsilon Andromedae, and Tau Bo?tis.

The results show that only the data information of the τ Boes system software mainly shows the prediction and analysis status obtained by scientific researchers when using Jupiter detection. This system software is located at a distance of 5.1 billion light-years from us. In 1996, biologists used the radial velocity method to discover a giant planet τ Boes b with a mass five times higher than Jupiter. It is precisely in this system software that the elite scientific research team finds the results they want to see.

Turner said: "We have confirmed that this kind of planet can send wireless communication data signals, from the compressive strength of wireless communication data signals, the polarization of light to the magnetic field of the planet, which are in good agreement with the theoretical inference results."

According to their scientific research, the compressive strength of the magnetic field of τ b Boes is about 5-11 Gaussian function. In comparison, the compressive strength of Jupiter's magnetic field, the strongest magnetic field of the solar system planets, is in the middle of the 4-13 Gaussian function. Then, everyone has reason to believe that τ Boes and Jupiter have the same internal structure that can cause a strong magnetic field, that is, a very large core composed of plated hydrogen, whose temperature and working pressure are terrifying. s level.

Such scientific research is more meaningful, as Turner often said: "The magnetic field of an terrestrial exoplanet can protect the planet's Earth's atmosphere from the solar wind and cosmic rays, and also avoid the outflow of the planet's Earth's atmosphere, which can improve its suitability. probability of survival."

For many years now, scientists have understood the key practical significance of magnetic fields in maintaining the beauty of planetary environments, and there is no way to detect whether exoplanets have magnetic fields alone. If the method of Turner et al. turns out to be reliable, it will be a huge improvement for everyone to find super-Earths in space.

Turner also emphasized: At this stage, the wireless communication data signals that they can detect are still very weak. In order to certify this method or use this method for scientific research in the future, they must rely on other low-frequency telescopes, which can help They look for the real source of this wireless communication data signal. Everyone expects that this is indeed the result of the harm caused by the exoplanet's magnetic field to the planetary wind, but it is not clear that it is very likely to be a planetary flare.

I firmly believe that scientists will certify this method as soon as possible, and once it is proven to be reasonable, there can be no doubt that we are one step closer to finding a second Earth.
