Hand rubbing nuclear fusion live in the wilderness

Chapter 550 Moon landing
Like the audience in the live broadcast room, Han Yuan standing in the No. [-] scientific research sub-cabin was also shocked by the sea of ​​stars outside.

This is a completely different feeling from looking at the Milky Way through the atmosphere on the earth.

After the huge volume of the No. [-] spacecraft blocked the sunlight from the back, when the eyes and brain automatically adapted to the darkness of the vast universe and received the light from the stars hundreds of millions of light-years away, the beauty of the sea of ​​stars was beyond words. to describe.

The long and narrow Milky Way spans the entire night sky like a gauze exuding faint brilliance, like a huge sky dragon, and like a Milky Way, shining into one piece.

The dark sky seemed to be a smoky band of light under the faint light of the Milky Way. It was very beautiful, full of stars, and it was impossible to see such a beauty on the earth through the atmosphere.

And in the sky, the Betelgeuse that exudes dazzling light is naturally impossible to be ignored by Han Yuan.

The two tails mentioned by the audience in the live broadcast room were even more eye-catching, and also aroused his surprise.

Looking at the bright Betelgeuse dragging two slender tail lines outside the window, Han Yuan frowned.

It has been almost half a month since the outbreak of Betelgeuse.

During this period, although the afterglow of the supernova explosion is still there, and the dazzling star light can still flicker and illuminate the entire galaxy, the gamma-ray burst should have faded theoretically.

Theoretically, the two magnetic poles of Betelgeuse where the supernova exploded should not have such a tail.

Suddenly, Han Yuan's pupils shrank suddenly, and he thought of a possibility.

"Xiao Qi, send me the latest photo of Betelgeuse taken by the Zero Outer Space Infrared Telescope, all of which are taken by infrared, ultraviolet and visible light observation array mirrors."

In the spaceship, Han Yuan called Xiaoqi, who was following the flight all the way, and asked him to pass over the latest photos about Betelgeuse.

Looking at the photos displayed on the virtual screen, especially the photos synthesized by the infrared primary mirror, Han Yuan's heart suddenly lifted.

For the Betelgeuse supernova explosion, the worst of the expected outcomes has emerged.

Betelgeuse, which has completed a supernova explosion, has evolved into a pulsating neutron star.

This is one of the worst possible outcomes of a Betelgeuse supernova explosion.

Even if it evolves into a black hole, or an ordinary neutron star is better than this result.

After all, although black holes are terrifying, where the mass of Betelgeuse is placed, at most a medium-mass black hole can be formed. Such a black hole has minimal impact on the solar system at a position 640 light-years away.

But pulsating neutron stars are different.

The rotation of a pulsating neutron star is normally very fast, and it usually only takes about five seconds to rotate.

Under this degree of high-speed rotation, the internal magnetic field vibrations often throw some electrons off the surface of the neutron star, resulting in super-strong radiation.

These radiations tend to gather and eject from both ends of the neutron star's magnetic poles, forming a magnetic pole conical pulse radiation region.

And this magnetic pole conical pulsed radiation can often sweep everything. Where there are pulsed neutron stars, the star fields within at least ten light-years around them are often barren of grass.

If it is in the magnetic pole cone radiation region of the pulsed neutron star, the barren region will expand to more than 100 light-years.

Intense radiation will directly kill all vitality, even with the protection of a thick atmosphere, it cannot withstand this kind of explosion at close range.

If the magnetic poles of the pulsar neutron stars formed after the Betelgeuse supernova exploded are aligned with the Earth due to the supernova explosion, even if the distance is more than 640 light-years, the Earth will be affected to a certain extent.

And whether the magnetic pole will change in the supernova explosion, this is an uncertain thing.

But in theory, because Betelgeuse and the solar system belong to the Milky Way, affected by the giant black hole Sagittarius A in the center of the Milky Way, its magnetic poles will generally radiate stably to the area outside the galactic disk.

To put it simply, if the Milky Way is viewed as an XY-axis coordinate system, the solar system and Betelgeuse are on the X-axis of the Milky Way.

The magnetic poles of Betelgeuse are only aligned on the Y axis because of the influence of the black hole at the intersection of the X and Y axes.

However, this situation is sometimes broken. For example, at the end of the 20th century, astronomers discovered a pulsar whose magnetic poles are radiating across the interior of the galaxy.

This unlucky neutron star, which broke the gravitational balance of the core after the supernova explosion but failed to reshape its core, swept across the star field of at least [-] light years in the same galaxy.

Under its super-strong radiation, life within these 200 light years will basically perish unless it can leave the parent star and immigrate to other planets.

Won doesn't want Betelgeuse to become like this.

Otherwise, even if it is more than 640 light-years away, human beings will still be affected.

A newborn pulsar emits radiation millions or even tens of millions of times that of the sun in one day.

Perhaps with the protection of the atmosphere, and the distance is relatively far enough, the creatures living on the earth may not see any changes in a short period of time, but over time, the impact will definitely be huge.

Ozone will be severely damaged due to perennial radiation, and various genetic mutations, biological mutations and other things will also greatly increase under radiation.

However, judging from the photos and related data passed by Xiaoqi so far, the magnetic pole of Betelgeuse did not change its angle significantly during the supernova explosion.

To be on the safe side, Han Yuan asked Xiaoqi to recalculate the angular velocity of Betelgeuse's magnetic pole conical radiation area based on the current data.

He breathed a sigh of relief after confirming that the magnetic pole cone radiation area still had an angular deviation of 27.8% from the solar system.

Life on Earth is lucky, once again avoiding disasters from the universe.

After confirming that Betelgeuse's magnetic pole cone radiation area and the solar system have an angular deviation, Won relaxes and enjoys the scenery again.

Betelgeuse, who was still worried just now, has become a treasure in his heart.

Compared with other neutron stars and stars, pulsar neutron stars are quite obvious and easy to observe in the universe because they can rotate at high speed and can send signals to the outside world.

Just like a lighthouse on the coast can guide ships in the sea, pulsar neutron stars are also lighthouses in the universe.

With such a lighthouse positioning, you don’t have to worry about getting lost when navigating in the vast universe.

Don't underestimate getting lost when navigating in the universe. This is a death threat that ruins the lives of most explorers.

The universe is too big. If you can't find a suitable planet to resupply, after the resources on the spacecraft are exhausted, there is only a dead end waiting for the crew.

The probability of finding an available resource star nearby by chance is less than one in a billion in the case of getting lost.

The star chart is as important as the nautical chart of the sixteenth century. Without it, ships would be lost in the endless sea.

The 36-hour sailing time was a long period of time in Won's original estimate, but the evolution of Betelgeuse plunged him into re-studying it.

In the blink of an eye, a slightly gray planet appeared on the virtual screen in the cab.

The camera mounted on the outside of the Zero spacecraft has perfectly stepped into the figure of the Moon, which is still small but clearly visible.

At the same time, the spacecraft officially entered the stage of decelerating into orbit and landing on the surface of the moon.

This stage is a very complicated matter for countries in reality, but it is very simple for the Korean won.

Sitting on the spaceship, he didn't even feel any obvious changes, and the spaceship had successfully entered orbit.

The rest is to continue to slow down and land on the surface of the moon.

This will take a little time, because it is the first landing, there are still some differences between the theory and the actual situation, the intelligent core of the spacecraft has to rearrange the data and adjust the spacecraft.

It took about half an hour before a behemoth landed on the surface of the moon.

After the spaceship landed on the surface of the moon, Han Yuan honestly put on his spacesuit in the spaceship, and then checked in the vacuum chamber inside the spaceship that there was no problem with the spacesuit before leaving the spaceship.

At the same time, behind him are two X-1 industrial robots that have been modified to use combined tracks, and a medium-sized probe car with a small safety cabin on top of the probe car.

The one that has been half-opened, as long as he enters the safety cabin, the safety cabin will be closed instantly, and the various small equipment inside will create an environment similar to the structure of the earth's atmosphere in a very short period of time.

Although there is no gravity, it is enough to support him to move about in it for about 10 minutes.

This time is enough for him to take off his spacesuit and replace it with a new one.

This is an emergency response that Won has come up with for himself.

After all, he went to space and landed on the moon by himself. If he didn't make some preparations, he might not know how he died.

In the solar system, Mars is probably the only one that can support humans to take off their spacesuits and survive for three seconds.

Mercury is completely ice and fire, the temperature can range from -150°C to 425°C, either grilled or frozen into popsicles.

Venus is an oven. The average temperature on its surface is as high as 462°C. Once you step on it, there may not be time for ants on the hot pan to burn.

The situation on Mars is slightly better. According to current observations, Mars is only suffering from lack of oxygen, low temperature and low pressure.

After excluding other influences, such as the influence of toxic gases, it may be possible to hop on the ground of Mars for a while without wearing a spacesuit and carrying an oxygen cylinder.

The exact time is uncertain.

After all, this won has never been tried. These are just theoretical inferences based on the Mars detection data. In theory, it is possible. As for the actual
As soon as he stepped out of the spaceship and before he went down the stairs, the weightlessness made Han Yuan jump up and down.

It is not easy to walk on the moon where the gravity is only one-sixth, even if the space suit he wears weighs a full hundred kilograms.

But under the gravity of the moon, this spacesuit is less than 20 kilograms, and it can be said that wearing it on the body will not affect activities at all.

Cautiously descending the stairs to the ground, and the moment his feet were on the ground, the Korean won had a subtle feeling.

In particular, the place where the No. [-] spacecraft landed has been screened. Here, you can see the blue and white planet in the distant starry sky at a glance.

There was excitement, but also a little bit of fear and unreality.

This feeling comes from the surface of the moon, space and earth.

Standing on the moon, looking as far as the eye can see, the cement gray earth refracts the sun's light, occasionally flashes a little silver light, and then extends to the dark space in the distance, where it is like an abyss, which can swallow everything.

The earth is motionless like a sticker, hanging in the center of the line of sight.

When all the pictures are combined, there is an abyss all around, and countless monsters just wait for the sunset to swallow you up.

Of course, this feeling is not very serious to Han Yuan, after all, he has been alone in the simulation space for seven or eight years, and he has already gotten used to loneliness.

Relatively speaking, the excitement of going to the moon is enough to cover up this subtle feeling.

After all, a few years ago, he never thought that he would be able to step on the moon himself in his lifetime. At that time, he could only stare at the sci-fi movie YY.

Now he waved his hand like a handful of moondust.

As he walked out of the spaceship, the live broadcast room became lively.

[One small step for the anchor!A big step for mankind! 】

【Is this on the moon?It looks so lonely, nothing but dirt. 】

【Fake, this is fake!It was filmed in a film studio and played for you guys!How is it possible to go to the moon? 】

[I heard that the moon is hollow, there is only a thin layer on the surface, and the inside is empty. Do you want to find a way to detect it? 】

【I know that the Leaning Tower of Pisa is hollow, but I don’t know about the moon... probably not, maybe it’s Chang’e’s cellar, or a moon rabbit farm.Because of the large temperature difference between day and night, the rabbit can't hold it! 】

【oops!Come, come, conspiracy theory, he is finally here! 】

[To be honest, the moon is my spaceship, but I can't go back now. 】

[Look less at the marketing account upstairs, did those cheating things tell you that the average density of the moon is 3.35g/cm^3, the average density is not very normal, blah blah, and then conclude that the moon is hollow? 】

[Fuck, how did you know? 】

[The moon is solid, just like the earth. Apollo lunar exploration brought seismometers to the moon to understand the internal structure of the moon by detecting the shock waves generated by meteorites hitting the moon, just like we knock on a jar to hear the sound.The detection results further show that the moon is solid, with a molten mantle and a solid core. 】

[It is true that the outside of the earth is a vacuum, but to say that the inside of the moon is empty is a bit of a loss of wisdom and bravery. 】

[Didn't it say that there are Chang'e and Moon Rabbit on the moon, and there is also a Guanghan Palace?Why didn't you see it? 】

【Hi everyone, I am actually Chang'e. I did not die after ascending to the moon. I just fainted from hunger. Now give me V50, and I will pinch a moon rabbit for you. 】

[The anchor walks so cutely, bouncing around. 】

[Anchor, stay here and don't move around, I'll plant an orange tree for you first. 】
