Chapter 50: Arriving at the Launch Nebula

The long journey is naturally not particularly long in the dream, just like taking a green train, except for a particularly long distance, basically a night's sleep is almost to the destination.

So, the voyage of 93 light years has also passed in a flash, and it will soon reach its destination.

First the alarm of the virtual world, then the revival of the real world, all of them came to their senses, looking at their bodies blankly, looking at their houses with a blank expression.

They have been asleep for too long, immersed in the virtual world, they already have a sense of strangeness to the real world, and they have to wander and observe carefully to pick up the deep things in their memories.

The fleet also quickly withdrew from curvature sailing, and now it was possible to observe with impunity.

The starry sky seemed to be covered with a thin veil, and the starlight in the distance dimmed a lot, but the near distance was not completely dark, and it seemed to be pregnant with the dawn of dawn.

Although the nebula is called the Emission Nebula, it is a bright nebula, but it is not directly visible to the human eye. Through advanced radio telescopes, it is possible to see that there are many emission lines in the nebula's spectrum on a very weak continuous background.

The launch nebula is still dominated by red, but also mixed with green, indicating that the launch nebula is mainly hydrogen, and some elements are free due to high energy.

Therefore, there must be one or more high-temperature stars around or inside this emission nebula, and under their high-energy radiation, the gas in the nebula is excited to emit light before it can be clearly seen by radio telescopes.

The color of a nebula depends on its chemical composition and the amount of free it is, but there is a good chance that a young star will be hidden inside, after all, a young star will cause some of the surrounding gas to be free during the birth process.

The nebula has been observed to be shaped a bit like a ship, which may be the result of a newly formed star emitting high-energy photons to excite interstellar gases to glow, while also producing strong star winds to change the shape of the nebula.

In summary, there is a high chance that the nebula will have young stars. So, the goal of the fleet is to find the young stars in the nebula and settle down for the time being.

The nebula is not a diffuse emission nebula, so the margin is relatively easy to determine, and the nebula is about 20 light-years wide and 7 light-years high, which is considered a large nebula.

Of course, it is not difficult to find a young star in this nebula, and with the dual action of the gravitational wave detection system and the neutrino detection system, four young stars were quickly found.

The closest one was less than 1 light year, which was very suitable for the fleet, so Liu Wei decided to go to that place.

The people who received the news were naturally overjoyed, which meant that the dream paradise they desperately longed for was approaching step by step.

Compared to the long journey of 93 light years, what is 1 light year?

The fleet, which again entered the curvature voyage, also quickly arrived there.

Every exit from the curvature voyage brings people hope, but this exit completely ignites the flame of hope.

There is a shining star here, and its not-so-round body spews out a large stream of hot matter from time to time, like a child playing.

There are a large number of stones drifting around, crashing against each other; There was a great cloud of gas, broken by the stones, but repaired again; Or the gas frolicking with some boulders, never stopping.

It's a chaotic playground.

All kinds of information were directly transmitted to Liu Wei, and he couldn't help but tremble his hands with excitement and hurriedly convened an emergency meeting.

As is customary, Han Qiao, who was in charge of intelligence, reported the specific situation.

His left hand trembled slightly, his eyelids jumped slightly, and his voice trembled slightly: "This is a protostar, to be precise, this star is still in the T stage of Taurus." ”

"In fact, this is both opportunities and risks for us, the T phase of Taurus is an unstable celestial body, it will undergo sudden changes, it will also suddenly change in brightness, it will eject matter in the form of jets, and its energy radiation is very strong, which is enough to hide us, it is difficult for extraterrestrial civilizations to cut through so many obstacles to find us."

"However, while its instability helps us, it can also pose a threat to us, we cannot determine the range of its energy radiation variation, and if it reaches a peak, it may cause damage to our warships, and it may also affect our exploitation of the resources of the star system."

"So we need to think carefully about staying here."

The birth of stars is wonderful, ordinary nebulae are very stable, only one percent of stars are formed by the accumulation of gas from ordinary nebulae, and the birth of most stars requires special perturbations, and there are about four common ones.

The first, more common, is a supernova explosion, which produces intense radiation that transforms nebulae into "hotbeds" for young stars, giving birth to stars.

The second is that the transport of spiral arm material in spiral galaxies causes density waves of the interstellar medium to propagate forward, compressing the gas wherever the crest goes, triggering star formation.

The third is also very common, and is mainly the chance encounter of two or more galaxies – passing by, passing through, colliding and even combining, in which gravity causes gas to accumulate in certain areas and causes gravitational collapse to form 8-year-old light stars.

The fourth is also intergalactic interactions, but a little more brutal, as their action can trigger a starburst, which can stir up a violent cataclysmic vortex that can lead to the birth of young stars.

After observation, the galaxy should be an elliptical galaxy, not a spiral galaxy. There are no galaxies around that galaxy, so the star may have something to do with a supernova.

Surprisingly, Jimmy, who has always been rigorous and reserved, actually stood up and asked, "Let me ask Minister Hancho, does this star system have a lot of resources for us to develop?" ”

Han Qiao paused, and then replied: "Yes, but the mass of this star is 1.2 times that of the sun, and after simple calculations, the life of this star has only gone through a journey of 20 million years, so it is impossible for planets to form immediately, and the resources here are mainly in the form of small meteorites, dust, gas clouds, etc., which are relatively scattered and not easy to collect." ”

Jimmy immediately asked, "What do you mean it's not easy to mine?" Doesn't our technology do anything about it? ”

Han Qiao didn't speak, but held his head and entered a thoughtful state, and the atmosphere on the scene began to be depressed.

Many people are beginning to think that this place should not be left behind, that the star is too young to gather resources around it, and that it will be very difficult to collect.

Moreover, the fleet could not land smoothly, and the fleet's defense system also needed to deal with a huge meteorite swarm.
