After the small celestial bodies in the solar system hit the earth’s atmosphere, they often generate high temperatures due to the mutual friction with the air, and in the process, they will also be accompanied by dazzling light. If they stand on the earth, they look like small fireballs. .
With the continuous improvement of modern technology, scientists have been able to observe more traces of “fireballs” with the help of advanced equipment and learn more about them.
However, according to the latest scientific research results, it is not only the small celestial bodies in the solar system that break into the earth’s atmosphere, but may also be in the Milky Way. Now, after 8 years of exploration, the U.S. Space Force Command has released research results. They found that the “fireball” observed in 2014 was actually caused by an object in the Milky Way.
A new discovery by U.S. Space Force Command
In 2014, a celestial body with a diameter of about 0.45 meters broke into the earth’s atmosphere, and its flight speed reached 210,000 kilometers per hour, much higher than the average flight speed of celestial bodies from the solar system.
After observing its orbit, some researchers accidentally found that the object’s orbit is hyperbolic , coming from 49.4 degrees of right ascension and 11.2 degrees of declination toward the earth, and the whole running speed is very fast , and the speed before falling is even higher. is up to 58 kilometers per second.
At that time, some scientists pointed out that perhaps this celestial body did not come from the solar system, and further research was carried out.
You must know that as long as it is a planet in the solar system, it will be more or less gravitational from the sun , but if the speed of the object itself exceeds a certain value, it can still get rid of the gravitational bond, and then use its own inertia. Leaving the solar system, this speed is called escape velocity, and is generally around 42 kilometers per second.
Obviously, the running speed of the object that fell in 2014 has exceeded the escape velocity , and the orbit is very special, indicating that if it does not enter the earth’s atmosphere , it will directly fly out of the solar system , that is, the object has the ability to fly out of the solar system, Suffice it to say that it itself may have come from outside the solar system.
In 2019, scientists finally determined that the object is indeed a celestial body outside the solar system, but this conclusion was not published in time, because some data information involved state secrets.
After more in-depth research, the U.S. Space Command released the news and officially released the memorandum retained. According to the research results in 2019, it can be proved that the objects in 2014 are not celestial bodies in the solar system, but celestial bodies in interstellar space. .
From this, the first interstellar guest from outside the solar system was not “Oumuamua” because it was observed after it was far away from the sun.
Many people are curious about what this object from interstellar space is. Scholar Amir Siraj pointed out that this object may also be a small celestial body, but it happened to fall into the earth’s atmosphere during interstellar travel, but even so, this Objects are still of great research value.
Because before the discovery of it, the scientific community has not found that a non-solar system celestial body has fallen into the atmosphere, even Oumuamua, which is regarded as the first exoplanet object, appeared later than it, if the specific situation of the object can be understood , will undoubtedly further promote the process of human exploration of the universe.
But now eight years have passed since the object appeared, and clues are very limited. A professor at Harvard University in the United States believes that this object from interstellar space may have fragments that fell to the earth. If it can be found and studied carefully, the desired answer may be obtained.
It’s just a pity that it exploded during the collision with the atmosphere, and its falling location was near the Pacific Ocean. The debris is likely to have sunk to the bottom, and it is very difficult to find the debris.
Will there be other aliens coming?
In fact, whether it is the solar system or other outer galaxies, there may be many celestial bodies falling to the earth, but not all of them can be found according to the current level of technology. Therefore, when Oumuamua was discovered in 2017, it caused turmoil in the entire scientific community. Because at that time everyone regarded it as the first alien from outside the solar system.
Some researchers believe that there may also be some alien guests in the solar system. After all, if the appearance of Oumuamua is not accidental, but an aircraft launched by alien civilizations to explore the universe, then these so-called alien guests may just be controlled by alien civilizations camouflage.
Just like Oumuamua, when it was first discovered, it was running faster and faster, and it looked like a runaway aircraft from a distance.
But this view has not been confirmed, and after rigorous analysis, the US Space Command believes that the probability of this assumption being true is very small.
Established in 2018, U.S. Space Command is a newly opened department of the Department of Defense, mainly to ensure and maintain the country’s dominant position in the field of space exploration, while addressing some related issues.
Although it was established for a short period of time, and the decrypted documents only released the original research results, its ability to integrate information is very strong, so the conclusions provided have a certain degree of credibility.
And scientists have also explained the phenomenon of celestial acceleration. Many celestial bodies, such as comets, are mainly composed of ice water and other mixtures. Therefore, in the process of approaching the sun, these substances will volatilize due to the increase in temperature, forming a driving force. It can also explain why the speed of the object will continue to increase.
Therefore, the speculation about alien civilizations manipulating celestial bodies into different galaxies is not very true. The arrival of extraterrestrial visitors is more affected by the gravity of the earth, so they fall towards the earth. This phenomenon is not uncommon and will appear in the future. a lot of.
Although scientists at this stage have not yet determined what the mysterious visitor in 2014 is, its appearance is of great help in promoting human exploration of celestial systems beyond the solar system. In the future, with the further improvement of the national scientific and technological level, I believe there will be opportunities to observe To the process of the arrival of more foreign visitors.
