The rise of nanometers

Yu Weicai distributed the scientific research equipment and materials transported this time to each laboratory in turn.

Currently, the number of resident astronauts in Mendeleev City is usually around 40, which is also the smallest among the major bases on the moon.

Most of the laboratories here tend to focus on theoretical research.

For example, there are seven laboratories on the far side of the moon, including the Yuan Tiangang Observatory, the Dark Matter Detection Laboratory, the Neutrino Detection Laboratory, and the Gravitational Wave Detection Laboratory, all of which are theoretically inclined.

Yuan Tiangang Observatory, that very large astronomical telescope, has also undergone another upgrade.

Although the combined lens is used, the area of ​​this astronomical telescope is much larger than that of the Hubble Telescope. In addition, the special environment on the back of the moon is very conducive to observing the wave frequency of the universe.

The people in charge of the observatory are Huang Gexin and Jiang Zhubo, who have worked at the Purple Mountain Observatory before. They are very young, one is 33 years old and the other is 27 years old.

Yu Weicai drove a trailer and handed over a batch of supplies prepared for the observatory to the two of them.

"Brother Huang, the things prepared by the Astronomy Bureau have arrived."

Huang Gexin, who was busy checking the telescope data, raised his head and asked: "Is it the material used to upgrade the lens?"

"Yes." Jiang Zhubo nodded.

"Let's go over and take a look!"

The two came to a simple warehouse. Since the standard cabins in Mendeleev City were limited, many supplies were placed in the simple warehouse.

This kind of simple warehouse is very simple. It is to dig a large trench. The depth is usually about 10 meters and the width is about 20 meters. The length is set according to the terrain and needs.

After digging the trench, erect foam silicon steel pillars and frames, then add a layer of sand-blocking aluminum alloy plates, and add one to two layers of composite lead plates on top of the top layer to enhance the overall anti-radiation and anti-electromagnetic interference capabilities. .

The last step is to compact the bottom of the trench, lay an aluminum alloy floor, and pile the excavated sand onto the top of the warehouse.

As for the exit, it is a small slope.

This simple warehouse does not require spare parts from Blue Star and can be built independently by relying on foamed silicon steel, aluminum alloy and composite lead plates produced in Guanghangong City.

Many materials that do not need to be stored in a special environment can be placed in this simple warehouse. After all, it does not rain on the moon, and medium-sized earthquakes rarely occur. This kind of warehouse can basically be used for a long time.

On the west side of the observatory, there is a simple warehouse dedicated to the observatory, with boxes of various sizes stacked inside.

According to the number, Huang Gexin and Jiang Zhubo quickly found something, a box half a person's height, about the same size as a sit-down refrigerator.

The two moved the box onto the bed of the electric pickup truck and returned to the observatory.

The Yuan Tiangang Observatory occupies a small area, only about 1,200 square meters. It is located on a hillside. The building is not a standard cabin, but a pyramid-shaped five-story building.

The astronomical telescope is on top of the building.

A large part of the space inside the observatory is underground, with a total of 15 cabins.

Jiang Zhubo removed the seven lenses of the astronomical telescope one by one and sent them to the TW-12 cabin, which is a small chemical working cabin.

In the chemical work cabin, Huang Gexin had already taken out the things sent from Blue Star from the box.

They are a vacuum electric field coating machine and a batch of raw materials for coating. The method of using the vacuum electric field coating machine is a one-click fool-like procedure, without any difficulty at all.

The expanded vacuum electric field coating machine can directly process mirrors with a diameter of less than 3 meters.

"Zhubo, give the mirror a thorough cleaning."

"OK."

After more than three hours of careful cleaning, the seven lenses finally became spotless, and then the first lens was fed into the vacuum electric field coating machine.

For the coating material option, Huang Gexin selected [Light Frequency High Sensitizer-1], which is a material that is extremely sensitive to gamma rays, and then pressed coating.

In the vacuum electric field coating machine, a layer of nano-film with stable structure and orderly molecular rehearsal is quickly formed on the mirror surface.

However, the coating work did not stop, but continued, because there was not just one kind of film that needed to be added, but more than twenty kinds.

This is mainly to improve the resolution and sensitivity of the telescope, so that the telescope can sense a variety of light waves.

After adding these films, the performance of this astronomical telescope will be greatly improved, and it can observe gamma rays, X-rays, ultraviolet, visible light and infrared rays.

Moreover, it is a very detailed distinction that can accurately judge the light waves of various frequency bands, which is very important for studying the universe.

Before being upgraded, this telescope could accurately observe within 32 light-years from the center of the solar system.

The accurate observation here means that we can see the star systems that exist within this range, as well as the relatively large planets inside the star system.

You must know that even the Hubble Telescope can only observe stars, and the situation inside the stellar system either requires specific conditions or can only be speculated through theoretical calculations.

Generally speaking, specific observation conditions mean that when a planet transits the sun, the planet in the star system happens to appear in the middle area between the parent star and the observation point. At this time, the obscuration phenomenon will occur.

Specifically, a black spot suddenly appears on the surface of the star, which indicates that there are planets in the star system.

However, this method of observation itself requires specific timing, and not all star systems are in a suitable position.

Although many star systems are disk-shaped, they are not in the same plane. The universe is three-dimensional.

The masking method has many limitations, so further technology is necessary, which is light wave high-sensitivity resolution technology.

The previous telescope mirror of Yuan Tiangang Observatory used high-sensitivity light wave technology, which is the first generation technology. The maximum range is within 32 light-years.

After this upgrade, the accurate observation range is estimated to be increased to about 200 to 210 light-years.

The results of this kind of observation data seem to have little use now.

In fact, it has a very important reference value for the star system science of the solar system. After all, there are still many unsolved mysteries in our solar system itself.

For example, previous observation data from the Yuan Tiangang Observatory have proven the existence of "dark stars".

The so-called dark stars, also called wandering planets, refer to planets that have not been captured by the star system. These planets are floating in the dark and lonely interstellar dark areas.

Currently, there are a total of 18 dark stars that have been identified within 32 light-years of the solar system. They are large and small, near and far.

The largest dark star is one-third the size of Jupiter; the smallest one is about the same size as the moon.

The closest dark star to the solar system is in the interstellar dark zone 2.034 light-years away.

This discovery fills some gaps in astronomical science, and also shows that the interstellar dark areas are not really empty.

The existence of these dark stars will also interfere with the operation of surrounding star systems, and they are also very dangerous.

If a dark star the size of the moon suddenly rushes into the solar system, it will have significant changes in the original operating mechanism of the star system.

Such changes may even directly exterminate humans.
