Space Travel: What did the spacecraft (Voyager 1 & Voyager 2) ,take out of the solar system? |
The mysterious dark space between the stars
has finally been shown by two fearless spacecraft, which have become the first
man-made spacecraft to go out of the solar system.
Our solar system ends are dark & extremely cold areas. There is an endless series of scares.
Since, beginning we have watched that from distance with extreme attention and the credit goes our Astronomers for this incredible job of exploring the vast expenses of the universe with billion of stars galaxies, comets etc.
Where did
the sun come from?
However, instead of the water
moving here and there, the turbulence is the result of solar winds, which is a
powerful spray of charged particles or a constant splash of plasma that stems
in every direction of the sun. As this plasma gas cocktail, space dust, collides
with cosmic rays, which fly between star systems and is called interstellar
medium. With the help of radio and X-ray telescopes, scientists have been
trying to figure out for the past century what the interstellar medium is made
of. They have discovered that it is made up of highly dispersed ionized
hydrogen atoms, dust and cosmic rays between deep molecular clouds of gas and
is thought to be the place where new stars are born.
But just outside our solar system, its true state is still a mystery, as the Sun, all eight planets, and the disk of debris of distant stars, popularly known as the Kapoor Belt, are all inside a huge bubble that Made by solar winds, called heliosphere. As the sun and its surrounding planets pass through the galaxy, the bubble constantly collides with the interstellar medium like an invisible shield, leaving a large number of harmful cosmic rays and other matter outside.
But its life-saving properties also make it difficult to know what is beyond the bubble. Even from the inside it is very difficult to know what its size and shape is.
How are planets created?
A change in the old ideology "Consider it looks like that you're inside your house and you want to know what it looks like from the outside world," says Eleena- Provrnikova, a researcher at Johns Hopkins University . To find out that go far away from the sun and look back but this is not an easy task. Compared to the Milky Way or the long galaxies of stars, our solar system looks smaller than a grain of rice in the Pacific Ocean. But the outer edge of the heliosphere is still so far away that it took Voyager 1 and Voyager 2 spacecraft 40 years to reach there from Earth.
Voyager |
Voyager 1, which took a more direct route through the middle of the solar system, entered interstellar space in 2012, while Voyager 2 did so in 2018. Both are currently about 13 billion and 11 billion miles above the Earth, respectively, and both are moving in space beyond our solar system, and in the meantime they are sending more data to us.
The car-sized Voyager spacecraft was launched in 1977 and is now sending data from interstellar space.
These two aging spacecraft have told us a great deal about the boundary between the heliosphere and interstellar medium, giving us fresh clues as to how our solar system came into being and how life became possible on Earth. Was Far beyond the boundaries of an epoch, the edge of the solar system actually produces stormy magnetic fields, collisions of astronomical winds, storms of extremely powerful matter, and rotating radiation coming from all directions.
As the sun's output or output changes, or as we pass through different areas of the interstellar medium, the size and shape of the heliosphere bubble begins to change. When solar winds are faster or slower, they also change the external pressure of the bubble.
In 2014, the sun's activity increased, sending a gust of solar wind into space. The storm immediately bathed Mercury and Venus at a speed of 800 kilometers per second. After covering two days and 150 million kilometers, it also surrounded the Earth. It took Fortunately, our planet's magnetic field protected us from this powerful and dangerous radiation.
The storm passed through Mars a day later, passing through the steroid belt, through the distant gas mountainous planets Jupiter, Saturn and Uranus, and more than two months later reached Neptune, about 4.5 billion kilometers from the Sun, also revolves in its orbit.
Six months later, the winds finally reached 13 billion kilometers from the sun. This place is called 'Termination Shock'. Here the sun's magnetic field, which pushes the solar wind, slows down so much that the interstellar medium can push it in the opposite direction.
With the termination shock, the solar wind blows at least half of its previous speed, as a hurricane subsides and turns into a tropical storm. Then in 2015 it went through the irregular body of Voyager 2, which is like a car. Voyager's 40-year-old sensitive technology discovered it. These sensors are still powered by a slowly decaying plutonium battery.
The spacecraft sent the data to Earth, which, although coming at the speed of light, still took 18 hours to reach here. The information sent by Voyager to astronomers came only because of the massive 70-meter satellite dishes and advanced technology. When Voyager was leaving Earth in 1977, the invention of this technology was unthinkable.
The sun constantly produces high energy particles called solar wind:
The solar wind spread collided with Voyager 2 while it was still in the solar system. After just over a year, the last gusts of this dying wind reached Voyager 1, which entered interstellar space in 2012.
The two spacecraft have taken different routes, which means that one spacecraft is 30 degrees above the solar level while the other is just as low. The gust of solar wind reached them in different areas and at different times, which gave very useful clues about the nature of Heliopas.
The data shows that this turbulent boundary is millions of kilometers wide and covers billions of square kilometers around the surface of the heliosphere.
The heliosphere is also unexpectedly large, which means that the interstellar medium in this part of the galaxy is much less deep or solid than previously thought. The sun passes through this interstellar space as the ark underwater, creating a 'bow-like wave' and leaving behind a change, which is similar to that of a possible comet-like tail (or more). Tails. Both Voyagers came out of the heliosphere's 'nose', so they did not send any information about the tail.
Helisphere’s are estimated to be about one astronomical unit thick (the average distance from sun to our earth), Provernikova describes. This is not really a level. This is a very serious area and we don't know what's going on there.
Not only do solar and interstellar winds create turbulent tug-of-war in this boundary area, but particle charges and velocity also appear to change. As a result, part of the interstellar medium is converted into solar air, and in fact increases the pushing out of the bubble.
And although solar wind can provide very interesting data, surprisingly it has little effect on the overall size and shape of the bubble. Factors outside the heliosphere seem to differ greatly from factors inside. Solar wind increases or decreases with time and apparently has no dramatic effect on the bubble. But if the bubble goes into the galaxy to an area where there is a deep or shallow interstellar, it shrinks and expands.
But there are still many unanswered questions.
By keeping the interstellar medium away, the solar wind also keeps away harmful radiation for life and harmful high-energy particles from space, such as cosmic rays. Cosmic rays are protons and atomic nuclei that travel at the speed of light through space. They can form when stars explode, when galaxies merge into black holes, and other catastrophic events occur.
Jamie Rankin, a researcher in heliophysics at Princeton University, says: "Voyager has finally stated that 90% of the radiation from the sun is filtered. Rankin is the first person to write PhD theses on Voyager's interstellar data.
NASA's three missions will soon be joined by Voyager spacecraft in interstellar space, but two have already run out of batteries and have stopped sending data. We all know how much data these little needles can send on their own about this giant temple site. Therefore, more expensive research needs to be done close to home.
NASA's Ibex (International Boundary Explorer) satellite, which has been orbiting the Earth since 2008, has discovered particles called "energetic neutral atoms" that pass through the interstellar boundary. Ibex prepares three-dimensional maps of these factors on the edge of the heliosphere.
The Ibex mission has discovered a ribbon of ultra-energy atoms that are pushed back from the edge of the heliosphere
Rankin analyzed the slight increase in solar winds using data from Voyager, Ibex and other sources. She is currently writing an article on the 2014 Big Bang. This shows that Voyager 1 was shrinking as it passed through the heliosphere, but when Voyager 2 passed through it, it was expanding.
"It's a very dramatic boundary," she says. It's great that this discovery has been photographed in 3D maps of Ibex, giving us the opportunity to see the local reaction from Voyagers at the same time.
Ibex has revealed how dynamic this boundary can be. In his first year, he saw a huge ribbon of energetic atoms that changed over time. It was later discovered that the ribbon-bearing area was the nose of the heliosphere, where solar particles bounced off a cosmic magnetic field and returned to the solar system.
However, although they have left the heliosphere, they are still exposed to many of the effects of our sun. The human eye can see sunlight, for example, from other planets. And our star's gravitational pull extends beyond the heliosphere, covering billions of miles of ice, dust, and space fragments called over-clouds.
Overt matter orbits the Sun, even though it is floating in distant interstellar space. Although the orbits of some comets reach the over-cloud, which is an area of 300-1,500 billion kilometers, it is still too far for us to send any mission.
Since the creation of the solar system, these distant things have hardly changed. So it is possible that the secrets of how the planets came into being, and how life appeared in our universe, are still hidden in them. And with every wave of new data, new secrets and new questions are emerging.
Provernikova says that a sheet of hydrogen may have covered some or all of the heliosphere, the effects of which are yet to be decoded. In addition, the heliosphere tends to lean towards the interstellar cloud, which is a collection of particles and dust formed after an ancient event and whose effects are still predicted on its boundary or the organisms living within it.
There may be temperature, there may be different magnetic fields, there may be different ionization and there may be many different parameters or factors. It's very interesting because it's an area of great discovery, and we know very little about the relationship between our stars and the local galaxy. "
In any
case, two objects as large as the size of a car connected to metal dishes will
be our first bodyguards to our solar system, which not only provided us with
the latest information about this strange and unknown region. He also showed
the way to distant worlds.
But two spacecraft, built and launched in
1970, have been showing us the world's first glimpses for the past two years
from this strange place we call interstellar space. As the first man-made
devices to move beyond the solar system, they are entering an area that no one
knows about, and which is billions of miles away from home. No other ship has
ever traveled so far and the secret they have revealed is that there is an
invisible region beyond our solar system where chaos and flying foam-like
activity take place.
