Since the first human landing in outer space, the exploration technology of outer space has become increasingly mature, and more and more probes have been sent out to the universe to explore outer space.
In 2018, the Japanese probe Hayabusa2 successfully collected samples from an asteroid 60 million kilometers from Earth and returned to Earth in December 2020, marking the first time Japan has successfully collected samples from outer space.
However, when Japanese scientists opened the capsule to study the asteroid samples, they found that a strange substance appeared in the capsule, which looked like a piece of silver tin foil, but when scientists analyzed it, they found that this substance was not silver tin foil at all, but a man-made substance.
What's going on here?
First, the technology of outer space acquisition is becoming more and more mature.
Since the end of the 60s of the last century, when human beings first sent probes to outer space, the technology of outer space exploration has been continuously developed and improved, and there are countless large and small probes to explore the mysteries of the universe.
With the continuous advancement of technology, the function and role of probes are also increasing, and people have detected more and more materials in outer space.
In 2003, Japan sent the Hayabusa1 probe to outer space to observe and study comets, which was the first time that Japan had carried out the exploration of a comet.
With the completion of the Hayabusa1 mission, Japan sent the Hayabusa2 probe to outer space in 2014, this time for the purpose of observing and studying asteroids.
On June 27, 2018, the Hayabusa2 probe finally arrived at its destination, on the asteroid Ryugu, which is about 320 million kilometers away from Earth.
After two years of observation and research, Japanese scientists finally decided to have the Hayabusa2 probe and the asteroid Ryugu have a close encounter for thousands of miles.
On February 22, 2019, the Hayabusa2 probe successfully collected some samples from the asteroid "Ryugu" and returned to Earth in December 2020, which is also the first time in human history that humans have successfully collected samples from an asteroid.
Japan has named the work on these samples as "Comet and Asteroid Probes", and these samples will be of great help to scientists studying the formation of asteroids and the early history of the Earth.
However, when Japanese scientists opened the capsule to study the asteroid samples, they found a silvery tinfoil-like substance in the capsule, which looked like a disc, about 5.4 centimeters in diameter and 0.1 millimeters thick.
At first, Japanese scientists thought that the capsule had been scraped off a layer of metal by materials from outer space on the way back to Earth, revealing the silver tin foil underneath, so they sent it to NASA at the Goddard Space Navigation Center for testing and analysis.
However, when NASA scientists analyzed the silver tin foil, it was found that the silver tin foil was not exposed by scraping off the metal skin at all, but was a man-made substance.
NASA scientists have conducted detailed tests and analyses of this man-made substance, but found that the source of this man-made material is very strange, it may have fallen from the earth, or it may have floated from outer space, but the specific thing, these scientists can not give an answer.
Scientists have also had some speculation about the specific origin of this man-made substance, but none have received a clear answer.
Second, it may be an extraterrestrial particle, or it may be an accidental substance.
However, what happened to the Hayabusa2 probe's return capsule with an artificial substance?
Scientists in Japan and NASA have conducted detailed tests and analyses of the man-made substance, but ultimately no results have been obtained.
So what exactly is this man-made substance?
This man-made substance is a kind of alien particle, the so-called extraterrestrial particle is a tiny particle floating from outer space to the earth, this particle may be emitted from comets and asteroids, or it may be a new substance formed in outer space.
Many extraterrestrial particles have been found on the earth, these extraterrestrial particles are very tiny, some of them cannot even be observed by the naked eye, but they have very peculiar physical properties, and some can even bring the properties of cosmic dust, which is of great help to scientists to study cosmic dust.
However, the origin of this extraterrestrial particle is a mystery, and scientists have been trying to find the answer to the mystery of the universe from extraterrestrial particles, but at present, extraterrestrial particles on Earth are still relatively rare, and scientists have very limited opportunities to study them.
However, with the continuous development and improvement of outer space technology, outer space probes can no longer only observe and study the environment of outer space, but also collect samples from asteroids and comets, which provides a new perspective for scientists to study the origin and formation of extraterrestrial particles.
It is for this reason that Japan has developed the "Comet and Asteroid Probe" and sent it into outer space for observation and research of comets and asteroids.
However, after the Hayabusa2 probe returned to Earth after collecting samples from the asteroid, scientists found a type of alien particle in the re-entry capsule, whether this alien particle fell from Earth or floated from outer space, and there is no answer yet.
NASA scientists have examined and analyzed the extraterrestrial particles in detail, but have found no anomalies, and the origin of the extraterrestrial particles remains a mystery.
There is a speculation that this alien particle may have fallen from the Earth, and it may be accompanied by some radioactive elements, but NASA scientists have tested this speculation, but they have not found that this alien particle contains radioactive elements, nor has it been found that this alien particle fell from the Earth.
So this speculation is also not valid, and there is also a speculation that this alien particle may have floated from outer space, but NASA scientists have tested this speculation, but have not found any outer space material.
Therefore, this speculation is not valid, and scientists need to do further testing and analysis on the origin of this alien particle.
3. It has attracted the attention of the world.
However, the exact source of such extraterrestrial particles is still unanswered.
After the Hayabusa2 probe returned to Earth from an asteroid, Japanese scientists studied the samples, but none of them found any anomalies, and the samples were all ordinary materials that did not help the scientists in their research.
Eventually, Japanese scientists handed over the samples to NASA, where NASA scientists could further test and analyze them to see if there were any other substances in the samples.
However, NASA scientists have tested and analyzed the samples, but they have not found any anomalies, and these samples are all ordinary substances, and no other substances are present.
NASA scientists have since tested and analyzed the extraterrestrial particles, but have not found any anomalies, and the origin of the extraterrestrial particles remains a mystery.
Scientists in Japan and NASA have examined and analyzed the extraterrestrial particles, but no results have been reached, and there is no answer to the question of what exactly the extraterrestrial particles came from.
epilogue
The study of such extraterrestrial particles is of great significance for scientists to study the formation of asteroids and the early history of the Earth, but the origin of such extraterrestrial particles is still a mystery.
As the technology of outer space exploration continues to mature, the role and function of probes are also increasing, but the occurrence of unexpected substances in scientific research also occurs from time to time, which shows that the exploration of unknown areas is complex and challenging, and requires more in-depth investigation and analysis.
The study of extraterrestrial particles is of great significance to mankind, and it may have a profound impact on the protection of earth's resources and environment, and future space exploration.
The successful exploration of Japan's Hayabusa2 probe shows the importance of international cooperation in the field of space exploration, and all countries should strengthen exchanges and cooperation to jointly promote scientific progress.
