"Voyager 1 has entered interstellar space?"
In 2012, some netizens saw the news about Voyager 1 flying out of the solar system and into interstellar space, and they were very curious about where the boundary of the solar system is and what kind of place it is.
However, the transmission of this information is intermittent, coupled with the understanding of different media in the transmission process, the information is distorted, resulting in untrue information, which makes many people more curious.
So where is the boundary of the solar system?
Did Voyager 1 fly out of the solar system and into interstellar space?
1. The Earth became the only planet where life existed.
In 2006, Pluto was removed by the International Astronomical Union, and since then Pluto has become a "dwarf planet", the original nine planets in the solar system have become eight planets, and the earth has become the only planet in the solar system with life.
The human beings on Earth have also become the only living creatures on the "civilized planet" in the solar system, and they are really from the "third planet".
In addition, in the 60s of the 20th century, mankind began to enter the space age, and successively launched probes such as "Lunar Probe", "Mercury Probe" and "Venus Probe" for space exploration, during which some information on planets such as "Moon", "Mercury" and "Venus" was also discovered.
In 1977, the United States secretly launched the Voyager 1 and Voyager 2 probes for space exploration, as well as to investigate the ability of outer space exploration technology.
After the two probes flew away from the Earth, they crossed the "solar wind" region, entered the "electromagnetic wind" region of the sun, and then entered the "solar system boundary".
When Voyager 1 and Voyager 2 flew out of the solar system and entered interstellar space, their signatures and nameplates became the first material placed in interstellar space by human beings, and they were also the first probes for human beings to enter interstellar space.
In 2012, some media broke the news that NASA sent the Voyager 1 probe to Earth and had flown out of the solar system and into interstellar space.
NASA experts who received the news said: "This news is from a real source", Voyager 1 has flown out of the solar system and into interstellar space.
NASA explained: "Several photographic points taken by the speedometer on Voyager 1 are used to calculate distances, and through these data, it is calculated that Voyager 1 left 50 kilometers and was the first man-made object to fly out of the solar system, enter interstellar space, and will fly forever to the depths of the universe."
For this reason, people are curious about the boundaries of the solar system.
Second, the information is distorted in transmission.
As Voyager 1 flew into "interstellar space", some news about the boundaries of the solar system also spread, but what are these news?
These messages are called the real messages of the "solar system boundary", but in the process of transmission, some transmission tools cannot be strongly received, resulting in the transmission of messages due to signal interference and other factors to reduce the authenticity, and the transmission of messages is mistaken by humans because of the transmission tools, however, this idea does not make sense
With the passage of time, the scope of Voyager 1's exploration has also expanded, and the boundaries of the solar system have often been concerned, and there are also many "boundary" news about the solar system.
For this reason, people are very curious about the boundaries of the solar system, but because some people speculate that Voyager 1 is only rotating after entering interstellar space, there are people who doubt whether the message is real, and even people mistakenly believe that the signal is jammed, so the message is delivered incorrectly.
And at that time, the technical level of transmitting the message was not enough, the signal was greatly disturbed, resulting in the transmission of the message was not easy, and the biggest problem was that there was not enough transmission range, due to the continuous expansion of the exploration range of the Voyager 1 probe, far away from the earth, resulting in the transmission of the message was also limited, and the biggest problem appeared in the repeated transmission and reception of the message.
After the message was repeated, human beings had doubts about the authenticity of the message, so even if NASA experts clarified: "The message is true", there were still many doubts.
In 2012, some media broke the news about Voyager 1's entry into interstellar space, which was recognized by some people, but many people expressed skepticism, so this news was not widely disseminated and gradually forgotten in people's memory.
Until July 2019, a foreign public account began to transmit: "The magnetosphere and plasma system around Voyager 1 have become smaller and smaller than the plasma system in the solar system."
The news has sparked curiosity about the boundaries of the solar system, and people have begun to search for previous information about Voyager 1's entry into interstellar space.
3. Where are the boundaries of the solar system?
So where exactly are the boundaries of the solar system?
According to experts: "The shape of the solar system is spherical, and Voyager 1 will need to fly for 30,000 years if it wants to leave the solar system."
The solar system is like a spider, it has a "web-like structure" of the family shell, and the solar system "belt", which is commonly known as the "meteor belt", is also within the scope of the solar system.
In the field of astronomy, the definition of the solar system is not only composed of the sun and the celestial bodies moving around the sun, but the laws of motion maintained by the gravitational pull of the sun, but the boundaries of the solar system were very vague until a "Voyager" probe flew away from the earth, crossed the "solar wind" region, and entered the "solar system boundary", the true extent of the solar system was revealed.
The boundaries of the solar system, also known as the "crossing point", are located at the junction of the "storm" and the "interstellar", and this is where the "traveler" flew for the first time, and people know the boundary of the solar system.
The regions of "storm" and "interstellar" are also known as "day layer" and "night layer", which are revealed by Antarctic atmospheric crust data.
At the same time, there is a defect in these two regions, that is, people cannot detect them through experiments, but can only obtain them through the data of the detectors, so the two detectors of "Voyager" play a key role.
The two Voyager probes were called Voyager 1 and Voyager 2, with Voyager 1 launched in the winter of 1977 and Voyager 2 launched in the summer of 1977.
The two probes also have different carryovers, with Voyager 1 having a redundant machine and Voyager 2 having no redundancy.
At that time, the launch design was also different, because the speed of Voyager 1 was faster and flew farther, so there were higher requirements for the launch design of the aircraft, and due to the limitation of load-bearing, there was no way to launch work, so redundant machines were designed in case of emergency.
The mission of the Voyager rover is to inflict an impact in the hope of bridging the terminals of the "storm" region around the Sun's magnetosphere to infer the shape of the Sun's magnetosphere.
At the time, the Voyager 1 and Voyager 2 probes carried a "Magnetic Field Project" to measure the magnetic fields of nearby planets with a one-part per million accuracy, and a "metal terminal" was built to detect magnetic forces, and at night it could be charged by the sun's light to provide energy to the wire.
epilogue
The two probes Voyager 1 and Voyager 2 both left the solar system and flew into interstellar space, but Voyager 2 was launched later than Voyager 1, so it has a higher flight speed and will soon be able to catch up with Voyager 1, that is, with the flight of Voyager 1 and Voyager 2 probes, mankind's grasp of the edge of the solar system will be clearer.
The detection capabilities of the Voyager 1 and Voyager 2 probes can enable them to work far away from humans, and at the same time provide important data for human exploration of the unknown world, providing important data for human space exploration in the future, and perhaps more probes will fly out of the solar system in the future to bring more discoveries.
The definition and perception of human beings at the edge of the solar system may also change with the deepening of scientific research, and the shape of the solar system may have new interpretations and understandings, and the existence and mission of Voyager 1 reflect mankind's exploration and desire for outer space.
