The decrease in the number of spaceships directly led to the desolation of Fangtai Port in Watson City. At this moment, most of the huge Taitai Port is closed except for some areas where workers are still on duty, and the energy should be plunged into darkness and cold.
Covering up the darkness, a beautiful small spaceship quietly left the port, entered the middle, and then accelerated and finally disappeared in the darkness. During the whole process, the port communication instruments were kept in contact with the spaceship and got a very compliant response station. The port workers did not receive a unified alarm, although the small spaceship was not so normal from any point of view.
After leaving Taigang, this small spaceship has been accelerating until it reaches 113 kilometers per second. For a small private spaceship, this speed is quite fast, and the fuel it can carry is limited. This speed base is close to the limit, so that it will take more than ten days for it to reach the vicinity of the earth to complete an interstellar journey across Mars and the earth.
However, this small spacecraft did not follow the fixed commercial route that had been laid out long ago and was full of navigation satellite material supply points. Shortly after leaving Mars, it deviated from the channel and deviated from the ecliptic plane. Only when there were few spacecraft passing through, did scientific research and military spacecraft come to advance strangely.
The front is huge and bright, and behind the sun is a vast expanse of Xinghai. In this way, the beautiful scenery surrounds this small ship, and it is silently suspended and still. It is only through the constantly changing figures of the instrument that we can realize that this small ship is moving forward and looking at the surrounding environment that no one can notice that this ship is moving forward.
After 13 days of quiet and quiet, the sun has become bigger and brighter, and the light blue star in front has finally changed from a point to a disk. If the line of sight deviates a little, you can see a faint white moon not far from this blue planet.
It’s less than five million kilometers away from the Earth. The distance of five million kilometers is not too far after the start of the interstellar voyage era. It can be regarded as quite close to the front. There will be too many patrol and supply inspection bases in human culture, and there is no way for the spacecraft trying to get close to the Earth to escape observation from these bases. At this moment, the pilot of this small spacecraft has prepared a whole set of deception and concealment procedures to deal with these bases.
But at this moment, the driver is preparing to approach the earth, and now the small spacecraft is facing the direction. One of the distant stars on the left side is too dim to be directly seen by the naked eye. When the star is very short, it suddenly lights up, and its brightness rises so rapidly. After only a few seconds, its apparent magnitude rises from 6.21 to MINUS 13-this brightness is almost brighter than the full moon.
So in the eyes of the spaceship driver, he can see this bright star besides the sun, the earth and the moon.
This bright star appeared so suddenly that it didn’t show any signs before it changed. It just appeared there, thousands of light years away, projecting its light into this small star and entering the eyes of the spacecraft driver.
The pilot of the spaceship knows that the star is called Haishan Erhai Mountain, which is a star system located at the base of the ship. This star system consists of two stars, but because of the thick interstellar dust clouds, human beings have not directly observed Haishan Erhai Mountain because it is too big and too bright.
Haishan II is a blue Supergiant star with the lowest mass. The sun’s luminosity is 120 times that of the sun, and it is more than 5 million times that of the sun. This intense luminosity is close to the Eddington luminosity limit, which will cause its surface radiation pressure to be very close to the star’s own gravity, which will make it extremely unstable and make it explode at a very high speed, throwing out a lot of matter. Scientists estimate that it has thrown out as little as 30 suns’ mass since its birth.
This is a young, violent and huge star. Generally speaking, the life span of such a star is very short. Tens of millions of years after birth, a big bang will end its life. People call this process of star death a supernova explosion.
Obviously … the star Haishan II just exploded and died. It ended its life in such a heroic and shapeless way that even if it was more than 7,000 light-years away, it still looked like a full moon, sending its death information to the sun and being detected by human beings.
The pilot of the spaceship knew that Haishan II explosion also announced the birth of a black hole, which was too massive. This kind of explosion would directly create a black hole at its core, instead of a medium star. Part of the material would fall back into the black hole and become other food, while the other part would form an accretion disk around it, and the explosive debris would spread continuously and eventually form a nebula.
Although the eruption of Haishan II is magnificent, it will not have much impact on the earth or the sun, because the distance is too far. Except for interstellar travel, ordinary people will not notice it except that there is another star in the sky whose brightness is like a full moon.
However, the eruption of Haishan II is a good thing for the pilot of this small spaceship. The pilot of the spaceship knows that after the eruption of Haishan II, the whole human attention will be attracted, and almost all the observation forces will be directed there, and the intensity of the spacecraft investigation will be reduced accordingly, which will help the pilot of the spaceship to muddle along more peacefully.
But this small spaceship didn’t get close to the earth in the end. After the distance between the earth and the earth was shortened to 3 million kilometers, it suddenly disappeared from here without warning, just like the eruption of Haishan II. It just disappeared.
No one except the original owner of the spacecraft will know that a small spacecraft once left Mars and came to Earth and eventually disappeared here, because it has no port record left in the Mars port, no port record left in the Earth port, and no navigation satellite or test left in its communication record.
The star is still quiet, as if this small ship had never appeared before.
Chapter one hundred and twenty-six Day interactive base
In a residential building in downtown Watson, Zhao Lan was asleep, and was awakened by a hurried bell. Zhao Lan pulled out her mobile phone from the bottom of her pillow with dim eyes and pressed a button, and a long-recorded video call message appeared in front of her eyes.
Because the distance between Mars and the Earth is too far away-the nearest distance between the two planets is more than 50 million kilometers, and it takes more than three minutes for magnetic waves to complete a one-way trip-which means that the communication delay between the two places is the lowest, and it is impossible for real-time communication between the two places. If people have communication needs, they usually record the information and send it. The information received by Zhao Lan is recorded and sent some time ago.
Zhao Lan took one look at the contact information and found that it was sent by Xinghai Sky Survey Base. The specific sender was his colleague Zhang Ya in Xinghai Sky Survey Base.
"Zhao Lan has an emergency. You must come back from your holiday before."
In the video message, Zhang Ya’s face is always delicate, and it looks a little dull and messy here-obviously this is because it was too urgent for Zhang Ya to send this message without makeup.
My friend Zhao Lan knows what it means for Zhang Ya to go out without makeup. It must be an extremely urgent matter that will happen. Zhao Lan’s mind is haunted by sleepiness. At this moment, Zhao Lan finally disappeared. She sat up and condensed her spirit to continue watching this video.
"Zhao Lan, do you know? Haishan II finally broke out just half an hour ago! We received a very strong gamma ray burst from Haishan II, which is different from the annual explosion in 143. It is better to find us than to make sure that Haishan II really broke out this time! "
"What?" Look at Zhang Ya’s face full of excitement, listening to her hoarse voice because of too much excitement, Zhao Lan also covered her mouth with shock.
Haishan II is a very famous star. Observing the evolution of this star is very important for human beings to construct a perfect supernova explosion mechanism. People have never relaxed their observation on it, but it is predicted that Haishan II will occur about 10 thousand years ago. No one ever thought that Haishan II would erupt now.
It can be predicted that this will be the strongest history of human astronomy. In the history of human literature, it is not that there has never been a supernova explosion-the most famous supernova explosion was observed in the Song Dynasty, which formed the famous crab nebula-but the human literature has enough precision observation equipment and is so close to the earth that the observation conditions are so good. However, the supernova explosion is the first time that Haishan II supernova explosion is bound to attract human attention in an instant. Compared with Haishan II, the hottest topic in human society, no matter what entertainment stars or famous sports stars, all have to make way.
The most important point is that Zhang Ya’s words confirm the authenticity of this explosion, which is a real explosion rather than a false supernova explosion that has happened before.
Supernova explosions are also divided into true and false. In 143, Haishan II had a false explosion. In that explosion, the brightness of Haishan II was much higher than that of Sirius during daytime, but the explosion was finally proved to be a fake. After observation and research, people finally thought that it was because Haishan II’s activity was too intense, which led to its luminosity exceeding Eddington’s luminosity limit. The radiation pressure exceeded its own gravity, so about one-fifth of a solar mass substance was thrown out by it and eventually caused its luminosity to be abnormally high.
This explosion is absolutely different. This is a real explosion of a giant star. Instantaneous fly ash and a limited amount of star material will be ejected into the interstellar space. A black hole representing its corpse will form elsewhere …
The eruption of Haishan II will drive astronomers and physicists around the world crazy, and Zhao Lan, an astronomer, is no exception.
In the video, Zhang Ya’s excited voice still came out, but Zhao Lan didn’t go to listen to it. Zhao Lan got out of bed as quickly as possible, dressed casually, washed her face, pulled up her suitcase and left here.
Zhao Lan saw the bright star in the sky with her own eyes through the huge and transparent glass cover in Watson City. The star in Zhao Lan’s eyes seems to have some strange magic that makes Zhao Lan want to watch it closely and don’t want to move his sight for a moment.
However, Zhao Lan knows that it is impossible to see anything with the naked eye. It is most appropriate to go to Xinghai Sky Survey Observation Base for observation and data analysis with the help of instruments there. Zhao Lan, an astronomer, must do her duty in this heroic event.
Zhao Lan stopped a car and quickly rushed to the interactive base in the sky. In the interactive base in the sky, there is a ladder connecting the ground and Taigang Port. Through the ladder, people can quickly leave the ground and enter Taigang Port to take a boat to the earth.
In the early days of the prologue of the interstellar era, people explored the design scheme of the near-earth and space-based spacecraft, but this scheme was finally abandoned by scientists and engineers. It is not that the human technology failed to meet the standard, but that the two spacecraft were built too high-it must have extremely tough armor system and extremely precise ship control system during take-off and landing, which will cause it to rise three times. Not only that, it must also carry it to break away from the gravity of the planet. When entering the atmosphere, it is necessary to accelerate and decelerate the fuel, which leads to its large design, which will make the overall structure design of the outer armor more difficult. For various reasons, people have to give up this design scheme.
