The vast universe of stars and sky is vast and boundless. No one knows where the end of the starry sky is. Anything compared with it is extremely small and insignificant.

In a place that was dark, gloomy, and cold, with a touch of eternity, the calm air without ripples suddenly rippled like waves of water.

Soon, the ripples became bigger and bigger, and slowly a little colorful light spots appeared, and soon slowly fainted. In a blink of an eye, it became a colorful and colorful channel of time and space.

From the space-time passage, a huge figure of a space battleship flew out quickly, and the lights on the battleship were bright, like a huge temple from the depths of the stars.

As the spaceship flew out, the wormhole in space-time also quickly and rapidly narrowed, disappearing in an instant, and the fluctuations in the void gradually returned to calm, as if nothing had happened. Only the rest This huge space battleship in the dark sky is as eye-catching as a firefly in the dark sky.

On the spacecraft ‘Explorer’, the people who ended the swift flight began to get busy. Various detectors were launched in all directions in order to control the void of the surrounding party and ensure their safety.

At the same time, the various detectors carried on the space battleship are all turned on, continuously receiving various information from the cosmic void.

As a cosmic astronomical scientist, Cao Yadong is the busiest. After each flying at a speed, he has to reposition the space battleship, and then re-correct the spacecraft's coordinate parameters based on the received information.

The cosmic starry sky is too wide. When it is in the void, there is no difference between front, back, left, right, and up and down, so the spacecraft is easily lost when it travels in the starry sky.

Especially as the space battleships are getting farther and farther away from the solar system, as the warp engines are getting more powerful, and they can jump more distant at a time, the probability of getting lost will increase.

The role of the cosmic astronomy scientist is equivalent to the compass on the spaceship and the battleship. It constantly gathers the received starlight to draw a more complete and detailed star path, locates the spaceship, corrects the coordinate parameters, and so on, to prevent it from being in the universe. Lost.

"It's been 88 light years from the solar system."

Cao Yadong and his team calculated the current location very quickly. After several months of sailing, they have left the solar system for a long distance of 88 light years.

"Draw the latest star map!"

Cao Yadong's idea connected the virtual world, and a star map appeared in his mind. This star map is a star map drawn by Xinghan cosmic astronomy scientists after a long period of observation, and it is also an indispensable thing in interstellar navigation.

Star maps are different from traditional geographic atlases or celestial photos. Star maps are accurate descriptions or drawings of persistent features in the night sky, such as stars, constellations of stars, galaxies, nebulae, star clusters, and other extragalactic galaxy drawing sets, so they are also called "Map of the stars".

Traditional maps are mapped according to geographical features. Rivers, rivers, mountains, lakes, etc. are important reference objects on traditional maps.

Of course, relying on modern scientific and technological means, drawing traditional maps can be very accurate, but in ancient times, drawing maps required important landmarks.

The same is true of star maps. Star maps are popularly called maps of stars, which contain all the stars that scientists can observe, and use them to draw a star map.

Maybe someone will say that the stars look exactly the same, there is no difference at all, any rely on the stars to identify the direction, positioning and navigation, etc.?

In fact, each star in the starry sky is completely different.

A star is a celestial body in the universe such as stars, neutron stars, comets, white dwarfs, etc. The distance, distance, mass, and intensity of light of these celestial bodies are completely different.

It looks exactly the same to our naked eyes, and there seems to be no difference between the stars, but it is completely different in the eyes of the cosmic astronomy scientist, and it is even hard to find two stars that are exactly the same.

The composition of the star map takes advantage of this.

Because each star is different, scientists can use these stars to navigate, locate, and calculate their detailed location.

This is the star map, a map of stars.

Of course, in the star structure star map, the only things that can be used as pointers are neutron stars and pulsars in the cosmic starry sky.

Neutron stars are the most dense stars in the universe besides black holes. They are also evolved from stars. Most pulsars are neutron stars, but neutron stars are not necessarily pulsars. Those with pulses are considered pulsars.

Because neutron stars have large mass and high density, neutron stars have many very special characteristics. One of them is the pulsation characteristic of some neutron stars. This pulsar is the brightest puppet in the cosmic starry sky and is the easiest target to find Naturally, it is equivalent to the mountains, rivers, rivers, etc. in the traditional map. It is a very important coordinate reference.

In addition, the energy radiation of neutron stars is millions of times that of solar radiation. Such a huge amount of energy radiation is like a lighthouse in the vast void, and it is very dazzling. Cosmic astronomy scientists can know at a glance.

Therefore, in a star chart, the most important are neutron stars and pulsars, because these two stars are the lighthouses in the cosmic starry sky, the reference objects, and the brightest puppets.

As for other stars, or stellar clouds, or constellations, etc., as the position moves, it is very likely that it will be difficult to observe, or some changes will occur and it will be difficult to find. not very accurate.

After a long period of observation and recording of Xinghan ’s cosmic astronomy science, many planetary systems in Xinghan were used as observations, and a huge expanse containing billions of stars, thousands of neutron stars, and pulsars was drawn. Illustration.

It is precisely based on this star map that the ‘Explorer’ spacecraft will not be lost in the starry sky when flying in the cosmic void, and will always be able to find its way home.

"A brand new neutron star was discovered, located in the central region of the Milky Way, about 7230 light years away from us."

Whenever a cosmic astronomical scientist arrives at a new place, the first thing he does is to observe the starry sky of the place, collect information about the stars in the starry sky, and then fuse it with the existing huge star map to carry out the star map. Continuous improvement.

"The sun is now just a faint little star."

Cao Yadong looks in the direction of the solar system. The sun belongs to the most ordinary child in the universe. It neither shines nor flashes. It is very ordinary and there is no place to shine.

When looking at the solar system at a distance of 88 light years from the solar system, the sun's rays are very weak and weak, and even the existence of the sun can be observed with the help of a cosmic astronomical telescope.

"The more you fly towards the galaxy, the denser this star becomes. As expected, most of the material in the galaxy is concentrated in the central area of ??the galaxy. I really want to go to the galaxy. Take a look at the center. The stars here should be extremely bright and dazzling. It is estimated that the distance between the stars and the stars may only be dozens of astronomical units. "

Cao Yadong carefully looked at the various information he received. This way, he continued to observe all the way, and he gradually discovered a pattern.

The closer this is to the center of the Milky Way galaxy, the denser the stars are, which also confirms a long-standing hypothesis of scientists because of the huge attraction of the black core of the Milky Way galaxy.

Most of the material in the galaxy is concentrated in the central area of ??the galaxy. As for the cantilever of the Orion cantilever in which the solar system is located, the proportion of matter in the banking cantilever is small.

Therefore, scientists have also made many reasonable inferences and conjectures. Now they have also verified this inference. The more they fly toward the galaxy, the denser the stars they observe.

"It is inferred that the Milky Way has not only black holes in the center of the Milky Way. The Milky Way is so large, but it is very stable. In addition to this core black hole, there should also be small black holes above the cantilever of the Milky Way."

"This black hole in the center of the Milky Way dominates the entire Milky Way ~ www.novelhall.com ~ Small black holes stabilize the Milky Way, but so far we have not found the existence of black holes on the Orion cantilever. Is this inference wrong? "

Soon, Cao Yadong also remembered a conclusion calculated and inferred by the scientific community of the Xinghan Universe and Astronomy scientific community using super quantum computers.

Based on a large number of observations, scientists have concluded that there are more than one black hole in the Milky Way. The black hole in the center of the Milky Way is a massive black hole that dominates the entire Milky Way.

In addition to this large black hole in the middle, there are small black holes in the Milky Way's cantilever and the outer Milky Way satellite galaxies, like the Large Magellanic Cloud.

It is the co-domination and effort of the black hole of this size that the entire galaxy can operate steadily and form a huge galaxy.

This time, the spacecraft that went out to explore was also taking into account the purpose of scientific research. For the cosmic astronomical scientists, one of their important tasks was to find small black holes above the orion cantilever, in order to verify scientists' inferences about the galaxy.
