In 1977, NASA and the Jet Propulsion Laboratory jointly launched the Voyager program, the most eye-catching of which was Voyager 1. It was launched the following year.
This was followed by the simultaneous launch of two Voyager probes, and at the end of the same year, the deployment of Voyager 1 and 2 was completed, sending them to the orbit of the outer planet of Jupiter, Thunderbolt VI, and then began in-depth observations of the mysterious clouds of Vulcanwick and the dry ice cover of Titan.
After all the work was done, Voyager continued deeper into the edge of the solar system, photographing the Nexperton ring, confirming that it was a gaseous ring, as well as a "cruciform storm" of Saturn.
In the process of going deep into the elliptical orbit, the storms and rings of Neptune were photographed, and the traces of the dispersion of the atmosphere of Mars and the disappearance of the Earth's atmosphere were photographed.
Eventually, it also captured a curved bow-shaped magnetic field on the meridian of the sun.
But three light-years from the Sun, Voyager discovered a strange thing: the vacuum was clearly multiplying...
So why is this happening?
Voyager's role in the solar system.
The purpose of the NASA Voyager program is to study the composition, size, and trajectory of supermassive objects in outer space, as well as their ray ringing effects, or their effects on the solar system.
The first two Voyager probes are the most anticipated, as they will be able to conduct in-depth research while navigating autonomously, providing useful information for humans and navigating vehicles.
In 1979, Voyager officially embarked on a journey to Jupiter, which was a relatively safe stage of the route, as they would first enter Jupiter's magnetosphere and make sectional observations of the magnetosphere before flying to other planets.
The purpose of this arrangement is not only to safely enter the magnetosphere after reaching the destination galaxy, but also to be on the safe side, once the probe fails, it can also change its trajectory through the gravitational attraction provided by Jupiter, and the probe will not fly into the star.
After more than two years of flying, Voyager arrived at Jupiter in early 1980 with first-hand information from Jupiter, and just a few days later, they arrived at Saturn.
After observing Titan, Voyager went into flight mode and traveled until September 1989, when it photographed Neptune's rings and completed its mission.
But in fact, even if the Voyager finishes filming the planned "road map", it can continue to play a role.
There may be a "voltamer" at the boundary of the solar system, that in front of the voltamic wall, there are no outer space objects in the solar system, which is caused by the magnetic shielding effect of the sun, which can block the outer space objects in the outer regions of the outer solar system.
But on the other side of the rear voltammetry, it is not magnetically shielded from the sun's radiation, so objects from outer space can pass through here.
As these objects pass through, they interact with various substances in the solar system, creating a ray cloud effect.
Inside the Earth, this phenomenon is not very obvious, but outside the Earth, it can be clearly observed.
This is also one of the important tasks of the Voyager: to observe the radiographic matter in outer space and the ray cloud effect.
The role of vacuum substances.
Voyager's observation of more mass in the vacuum may lead to one of the most common hypotheses: that the observed "slow" expansion of stars may be due to the fact that the solar system is constantly attracting material from outer space, and thus gradually grows larger.
Generally speaking, this conjecture is not valid, because the matter absorbed by the solar system on an order of magnitude cannot be compared with the volume of stars, and even if the volume of the solar system is expanded by more than ten or even hundreds of times, the absorbed material is still pitifully rare.
This is because unless the material is dense enough to form a very noticeable gravitational field, and most of the outer space matter is very dense.
Even around "dense" stars, the density of matter in outer space may not be comparable to the density of Earth's atmosphere.
Of course, if some matter is too dense and dense enough, it is possible to become a black hole, but this is also extremely rare.
So why is the density of these outer space materials so small?
This is due to the fact that their gravitational and thermal forces are very small, and they are very little affected by external forces, and they are almost impossible to aggregate.
In this case, matter is in the universe, and it is difficult to form solids.
In the beginning, some of the material in the solar system began to accumulate, but as the sun formed, the sun's gravitational pull thinned out the material in the solar system.
At the same time, as the distance between the sun increases, there is more material in outer space, because the heat of matter in space is too small due to the gravitational pull of the sun to make the atoms in the matter move faster, resulting in thinner gases.
In the case of outer space, large and small objects cannot be formed.
This is also the reason why the density of matter in outer space is very small, and it is also why the solar system cannot absorb materials in the process of its own high-speed motion.
Why do you get more.
The amount of matter in outer space is very scarce, even scarcity than the population on Earth.
In the process of high-speed motion of the solar system, under the action of outer space objects, these objects will collide with the atoms and molecules in the matter of the solar system, so that where the matter collides, heat energy will be generated, and these heat energy will evaporate some of the gaseous substances of outer space matter, making them thinner.
As a result, Voyager observed more and more gaseous matter around the solar system, probably because the thermal energy generated by their collisions no longer interacts with matter, so the outer space matter will become more and more gaseous.
The more gaseous matter there is around the solar system, the more likely it is that objects in outer space will interact with them and have an effect on the material of the solar system.
In this way, it is possible for the outer space material to generate a magnetic field near the solar system, which can interfere with Voyager, so Voyager needs to conduct in-depth observations of the outer space material in the solar system to rule out the effect of the magnetic field attached to the outer space material on them.
epilogue
Through the observation of material at the edge of the solar system, Voyager has greatly helped mankind to study materials in outer space.
This has also accumulated valuable experience for human beings in the process of further exploration of the universe.
