Chapter 481

Pre earth era, Pingtang County, Guizhou Province, China.

Now it is the blood moon information tracking station of the astronomy Bureau of the local National Academy of Sciences.

In the pre earth era, the Chinese Academy of Sciences put forward the idea of building a 500m aperture spherical radio telescope using karst landform in 1995. In 2007, the project was approved by the state and became one of China's nine major scientific and technological infrastructure.

Originally, the construction of this astronomical telescope was planned to be completed by the end of 2016. However, due to the construction of some projects, the ground was not broken until 2011, and the closure of the ring beam was just completed in 2014. The slow progress of the project does not match its name.

The English name of the world's first giant spherical radio telescope with a diameter of 500 meters is "fast", which means the first speed in the universe. The construction speed is really not flattering. Every fine part has been repeatedly considered and considered.

Because of this, the world's largest astronomical telescope will not be officially put into use until 2020, which is already after the first year of the end.

Perhaps it was precisely because it was not put into use that it just escaped the reconnaissance and attack of the blood moon spacecraft. Several of the largest telescopes on the earth at the same time were damaged by mechanical warfare insects to varying degrees, including the European very large optical telescope in Chile's Atacama Desert and the very large radio telescope array in New Mexico.

China's fast survived. Together with the "green bank", the largest parabolic radio telescope in the United States, it has become the best tool for scientists in the post earth era to observe the universe and track the footprints of the blood moon.

Earth people never wait for the arrival of the blood moon. After the establishment of the earth country after the end of the day, Xu zhe set up the earth country astronomy Bureau and transferred the best astronomy and physics talents in the pre earth era from the Academy of Sciences to Pingtang County, Guizhou Province to track the trace of the blood moon fleet and calculate the orbit and landing time at any time.

Now, more than ten years later, scientists finally captured the figure of the blood moon spacecraft fleet again from the radio signal. They printed the radio signal and reported it to the local head of state's office.

Professor Naduo stared at the report for a long time, and then immediately organized personnel to conduct field inspection at the astronomical Bureau. It was a long way, and the quickest way was, of course, with the help of Hao Zhi's transition.

Hao Zhi doesn't care. Now he has almost endless energy and physical strength. He can drive hundreds of people to jump together at any time. It's a matter of one second wherever he goes.

Professor nado is standing in the survey Hall of the National Astronomical Bureau, which is located next to the central control room at the lower part of the feed module, where the data is collected.

"Hold the grass, such a big telescope, come on, let me see what captain xueyuefei looks like?" Hao Zhi couldn't help being excited as soon as he arrived here.

"You're mistaken. There's no Observatory here. We use radio telescopes, not optics. Optical telescopes can directly see images, while radio captures radio signals, not directly observed with the naked eye." the director of the observatory is an old man in his fifties. I don't know if it's because of the arrival of the highest leaders of the country, his face is pink, Like some kind of skin disease.

He transferred the observation results of the day from the computer and projected a large light spot in the playback pool in the center of the control room using holographic technology.

The messy light spot is like a huge hemp ball. Thousands of bright spots representing stars flicker slightly, some are bright and some are dark, and some are rotating around each other. He wears a strange glove on his hand. Some sensing lines outside the glove are connected with five fingers. Raise his hand and move, and the holographic image in the playback pool moves with him.

He made a gesture of opening his five fingers, and the three-dimensional picture of the Milky way in the holographic image was magnified several times, highlighting an area labeled red.

"This is our solar system. The red one in the center is the sun, and the little blue dot is the earth," he said, pointing to the simulated solar system.

"So small?" Hao Zhi did not look at the faint blue dot, but spread his vision and noticed the huge Milky way outside. The difference in this ratio is too great.

Like a sesame in a huge swimming pool, and that sesame is not the earth, but the solar system

"Then, in which direction is the blood moon fleet?" asked Professor nado.

"In this place!" the astronomy curator adjusted an angle and continued to explain, "according to our current position, in the south of the sky, it is the brightest star in the sky that we can observe except the sun. It is also a first-class star in Canis Major, which is named Canis Major according to Bayer's star naming method α Star. In China, Sirian officials who belong to Jingxiu among the twenty-eight stars... "

"Sirius?" Hao Zhi repeated suspiciously. "No wonder he bites when he sees people. This thing is too wild and belligerent!"

"Ha ha, you can also understand this..." the astronomy curator smiled flatteringly. "According to our observation and data analysis in the past ten years, the parent star of blood moon man is likely to be a planet or satellite from Canis Major."

"Why do you say that?" Hao Zhi pointed to the stars in the sky. "There are so many stars, how can we be sure it is it?"

"Hehe, it's very simple. Although there are many stars in the deep sky of the universe, most of them are far away from our solar system. According to the basic conditions we know so far, assuming that what the blood moon people say is true, it took 500 years for them to fly from their parent star to the earth, we can find any star system more than 10 light-years away from us I don't need to think about it, because at a distance of more than 10 light-years, unless it can reach more than one tenth of the speed of light, Galaxy level voyage is impossible... "

"Yes, I heard Xingchen say once that the space speed of their blood moon family was about 1% of the speed of light. At that time, I guessed that their hometown was about 10 light-years away from the earth. He gave a positive answer!" Wang Yanke suddenly remembered Xingchen's words.

"Well, the blood moon man did not lie about this. Within 10 light-years, within the interstellar range, we have only two choices, one is Sirius and the other is Nanmen 2. Relatively speaking, Nanmen 2 is closer, only 4.3 light-years away from the solar system, and Sirius is twice as far away from us, 8.6 light-years."

"What if it's the southern gate?" Hao Zhi obviously doesn't like the name Sirius.

"Nanmen 2 is a trine star in Centaurus, that is to say, it is actually composed of three stars entangled and rotating around each other. We theoretically believe that life cannot be born in that environment. Who can imagine that there are three suns overhead. How can animals live?"

Well, it's so close... Hao Zhi doesn't care about each other's language description. He just stares at the things displayed in the picture with his eyes. It's more intuitive. On the holographic star map, the sun and the two adjacent stars almost coincide face to face.

This face to face distance will take 500 years

Looking at the whole universe, Hao Zhi suddenly realized why divine civilization should go to the edge of the universe. Simply having this idea is already a great ambition
