The vast starry sky of the universe is vast and boundless, and no one knows where the end of this starry sky is.

In a place that was pitch black, dark, and cold, with a hint of eternal aura, the calm Skyclave without a trace of waves suddenly rippled, like water waves.

Soon, the ripples became bigger and bigger, and slowly a little colorful light point appeared, and soon it slowly faded away, and in the blink of an eye, it became a colorful and colorful space-time channel.

From the space-time channel, the huge figure of a space battleship flew out rapidly, and the battleship was brightly lit, like a huge temple from the depths of the starry sky.

As the spaceship flew out, the space-time wormhole also quickly shrunk rapidly, disappearing in a blink of an eye, and the fluctuations in the void gradually calmed down, as if nothing had happened, leaving only this huge space battleship in the dark void, like a firefly in the dark starry sky, so eye-catching.

On the spaceship "Explorer", the crowd that had finished flying at warp speed began to get busy, and various probes were launched in all directions in order to control the void around them and ensure their own safety.

At the same time, the various probes carried on the space battleship are also all turned on, and they continue to receive all kinds of information from the void of the universe.

As a cosmonastic scientist, Cao Yadong is the busiest, after each warp flight, he has to relocate the position of the space battleship, and then combine the received information to re-correct the spacecraft's coordinate parameters.

The starry sky of the universe is too vast, and when you are in the void, there is no difference between front and back, left and right, up and down, so it is easy for the spacecraft to get lost when flying at warp speed in the starry sky.

Especially as the space battleship gets farther and farther away from the solar system, as the warp engine becomes more and more powerful, and it can jump farther distances at once, the probability of this getting lost will increase.

The role of a cosmological astronomical scientist is equivalent to a compass on a spaceship or warship, constantly gathering the received starlight to draw a more complete and detailed star path, positioning the spacecraft, correcting coordinate parameters, etc., to prevent it from getting lost in the cosmic void.

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

Cao Yadong and his team quickly calculated their current location, and after several months of sailing, they had left the solar system for a distance of 88 light years.

"Draw the latest star map!"

Cao Yadong's mind was connected to the virtual world, and a star map appeared in his mind, which was drawn by astronomical scientists in the Xinghan universe after a long period of observation, and it was also an indispensable thing in interstellar navigation.

Star maps are different from traditional geographical atlases or celestial photographs, star maps are atlases that accurately describe or draw lasting features in the night sky, such as stars, constellations composed of stars, galacies, nebulae, star clusters and other extragalactic galaxies, so they are also called "star maps".

Traditional maps are drawn and measured according to geographical features, such as large rivers, mountains, lakes, etc., which are important references on traditional maps.

Of course, relying on modern technology, traditional maps can be very accurate, but in ancient times, maps were drawn with important landmarks.

The same is true for star charts, which are commonly known as maps of stars, which include all the stars that scientists can observe, and use some of them to draw a star map.

Some people may say that the stars all look exactly the same, there is no difference at all, any reliance on the stars to identify directions, locate and navigate, etc.?

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

A star is a star, neutron star, comet, white dwarf and other celestial bodies in the universe, the distance of these celestial bodies, the size of the mass, the intensity of the light, etc., these information are completely different.

Stars that look exactly the same to our naked eyes and seem to have no difference are completely different in the eyes of cosmic astroscientists, and it is even difficult to find two identical stars.

The composition of the star map takes advantage of this.

Because each star is different, scientists are able to use these stars to navigate, locate and calculate their detailed position.

This is the star map, a map made of stars.

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

Neutron stars are the densest stars in the universe in addition to black holes, and they are also evolved from stars.

Because of the large mass and high density of neutron stars, neutron stars have many very special characteristics, one of which is that some neutron stars have the characteristics of pulses, which are the brightest in the cosmic starry sky and the easiest targets to find.

In addition, the energy radiation of neutron stars is millions of times that of the sun, and such a huge amount of energy radiation is like a lighthouse in the vast void, which is very dazzling, and cosmic astronomical scientists can know it at a glance.

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

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

After a long period of observation and recording, Xinghan's cosmic astronomical science has been observed in many planetary systems in Xinghan, and a huge and vast star map containing hundreds of billions of stars, thousands of neutron stars, and pulsars has been drawn.

Relying on this star map, the Explorer spacecraft will not get lost in the starry sky when flying in the cosmic void, and will always find its way home.

"A brand new neutron star has been discovered, located in the central region of the Milky Way, about 7,230 light-years away."

The first thing astronomers do when they go to a new place is to observe the starry sky of the location, collect information about the stars in the starry sky, and then integrate it with the existing huge star map, so as to continuously improve the star map.

"The sun is now just a faint star."

Cao Yadong looked in the direction of the solar system, the sun is the most ordinary boy in the universe, neither bright nor shining, very ordinary, without a trace of brilliance.

When looking at the solar system from a distance of 88 light-years, the sun's rays are so weak that it takes the help of a cosmic telescope to observe the sun's existence.

"The more you fly in the direction of the Milky Way, the greater the density of the stars, and sure enough, as expected, most of the material in the Milky Way is concentrated in the central region of the Milky Way, I really want to go to the center of the Milky Way to take a look, the stars here should be incomparably bright, dazzling, it is estimated that the distance between the stars and the stars may only be a few dozen astronomical units."

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

The closer this is to the center of the Milky Way, the denser the stars become, which also validates a long-standing assumption by scientists because of the enormous attraction of black holes at the core of the Milky Way.

Most of the matter in the Milky Way is concentrated in the central region of the Milky Way, and the cantilever of the banking system such as the Orion Cantilever where the solar system is located occupies a very small proportion of matter.

Therefore, scientists have also made a lot of reasonable inferences and conjectures, and now they have verified this inference, the further you fly in the direction of the Milky Way, the greater the density of observed stars.

"According to the inference, there is not only a black hole in the center of the Milky Way in the Milky Way, the Milky Way is so large, but it is very stable, in addition to the core black hole, there should also be a small black hole on the cantilever of the Milky Way."

"The black hole at the center of the Milky Way dominates the entire Milky Way, and the small black hole plays a role in stabilizing the Milky Way, but so far we have not found the existence of a black hole on the Orion cantilever side, is this inference wrong?"

Soon, Cao Yadong also remembered a conclusion that the scientific community of Xinghan Universe astronomical science used super quantum computers to calculate and deduce.

Based on a large number of observations, scientists have deduced that there is more than one black hole inside the Milky Way, and the black hole at the center of the Milky Way is a massive black hole that dominates the entire Milky Way.

In addition to the large black hole in the middle, there are also small black holes in the cantilever of the Milky Way, and in the outer galaxies of the Milky Way's satellites, such as the Large Magellanic Galaxy.

It is the joint domination and efforts of these large and small black holes that the entire Milky Way can operate steadily, forming a huge Milky Way.

This time, the spacecraft that went out to explore was actually for the purpose of scientific research, and for cosmic astroscientists, an important task for them was to find the small black hole above the cantilever of Orion, so as to verify the scientists' inference about the Milky Way.
