The empty mountains are lonely, the cold moon is like a hook, and the stars in the sky are suspended above the canopy, and the spots of light are shining and dotted.

A huge pot lies quietly in the valley, this pot has reached a diameter of more than 500 meters, and it is the largest single-aperture spherical radio telescope of Bluestar to date.

The Blue Star Huang National Academy of Sciences named him HUA. Due to his large caliber. HUA can see farther into deep space and help explore intelligent life in the universe.

Study the universe in its most primitive form. The radio telescope located in this valley was creatively proposed by scientists from Huang Guo to use the karst depression of this valley to build a 500-meter aperture spherical radio telescope, and turned it into reality.

4,600 units have been creatively laid in the crater to form a 500-meter spherical coronal active reflective surface, and a light cable dragging mechanism and a parallel robot will be used for the first time to achieve high-precision positioning of the telescope receiver.

This is by far the most advanced and powerful radio telescope and the largest space exploration project of Bluestar, which can be automatically attended and automatically analyzed and tracked.

On a jutting hillside, there is a large flat land with a standard football field and a basketball court on the flat land, next to the basketball field.

Depending on the topography, there is a badminton court and a tennis court. The badminton and tennis courts have a light awning above them to provide shelter from the wind and rain.

Next to the sports field, a large number of houses are built against the hill, forming a unique style. From the outside, it looks like a large area of buildings is crawling on the mountain.

A majestic gatehouse stands in the middle of the building, and the whole mountain seems to open a huge mouth.

The four guards at the gate stood straight, staring intently and vigilantly at the front of the gate, and nothing could escape their gaze.

After entering the gate and passing through the corridor, three large roads stretched in three directions, and one in the middle went straight into the belly of the mountain. A heavy gate cut the road through.

On either side of the gate stood two guards, armed with guns and ammunition, watching warily. At the foot of the mountain, there are four cedar trees standing in two flower beds, which make the surrounding area look even deeper.

Passing through the door, inside is an empty hall, and inside the hall are rows of equipment that are functioning automatically and efficiently.

Analyze and organize the collected information to filter out the clutter and useless information of normalcy.

Useful information and special signals are forwarded to two 24-hour manned computer rooms next to the hall.

Now the two young people in the computer room are listening quietly, and their faces are solemn and unprecedented.

All the listening equipment next to it was also turned on, and a row of people stood behind the two young people, and it was the leaders of the entire base who were in columns, staring intently at the operation of the two young people.

Under the gaze of the leader, the two young people did not dare to be a little sloppy. I didn't bother to wipe the sweat off my face.

I can't wait to embed my ears into the headphones. The radio waves are something that has never been heard before, and the large flat on the wall is showing the characteristics of this kind of radio waves.

It looks like a communication band, but this kind of radio wave has never been used for communication on Earth.

It is an ultra-long wavelength radio wave, and the source is not very far away, just in low earth orbit. Two young people, one listening and recording content, the other looking for the source of the radio waves.

The room was so quiet that you could hear a needle drop on the floor, and everyone held their breath, fearing that their movements would affect the young man's operation.

For so many years, there had never been a message so close to humanity, and no one was not excited.

It's not a question of winning an award, it's probably going to change the history of mankind. So when they received the notification, all the leaders in the base came to this room as quickly as possible, which was really not inferior to the speed of the soldiers on the battlefield.

Don't look at the fact that these professors are not young one by one, at this time, everyone is in high spirits, with solemn faces, and they are not willing to miss this historic moment.

"The radio waves are coming from apogee 35,786 kilometers," the listener in charge of tracking said, looking up at the person behind him.

"Star Map" An old professor with white hair waved his hand decisively and shouted.

The young assistant quickly carved out a large screen on the wall and called up a star map near the Earth. All the spacecraft, planets, asteroids, comets, moons, and even slightly larger meteorites around the Earth are numbered.

The old professor took out a laser pointer and handed it to the monitor, "In which range?"

The listener took the laser pointer and drew a circle with a diameter of about 1,000 kilometers centered on apogee 35786, and explained: "It must be in this range, very clear." ”

1000 kilometers is a large range on Earth, but in the universe, it is already a very small value, you must know that the distance unit in the universe can be calculated in light years.

At such a close distance, there is a signal of intelligent life in such a small area, right next to the earthlings, which is really incredible. The old professor's brow furrowed.

"Not mistaken"? The old professor asked suspiciously.

"Absolutely, yes". The listener said categorically, "I've checked it again and again." The listener was very sure.

"The transmission stopped," reported another listener, who looked up at the time, which lasted for about half an hour. He recorded the time of the last stop, which is also important information.

The old professor did not speak, it seemed that he was the most authoritative in the group, and everyone looked at him and waited for his decision.

After a while, he muttered, as if to others, and as if to himself, "Could it be that the earthlings are moving there, conducting new communication wavelength experiments"?

"Mark the human spacecraft in that area, and the military will confirm it to the military." The old professor said to the listener who was tracking the location.

"Okay". The listener agreed, and skillfully called up a star map to mark.

"Let's go out, to Room 1, and we'll talk about it when they get the results out." After the old professor finished speaking, he led everyone outside.

"Could it be that it is not a communication signal"? A middle-aged researcher asked the old professor with uncertainty. He just looked at the state around 35786, and it really didn't stand out, it was like that state a long time ago, so it can be said that there is nothing abrupt.

"I'll talk about it later", the old professor did not explain.
