Seven bright blue lines drew seven graceful arcs, and then docked precisely at the spaceport of a mothership at the heart of the expeditionary fleet. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

"Shuchun, inform the officials above the commander level who are on duty to attend the meeting in the first conference hall!"

After returning to the central command center, Yuan Haochen immediately summoned all the senior command officials who were in a state of awakening.

"Yes, leader." Ye Shuchun, the work assistant, immediately went to arrange the relevant matters.

......

About three hours later, all the senior commanders who were supposed to be present had gathered in the First Conference Hall of the Expeditionary Force.

"Everyone! Let Wang Yao first briefly describe the scientific research and exploration of the blue supergiant Cygnus P. Yuan Haochen took the lead in saying.

Subsequently, Wang Yao, the deputy commander of science who participated in the whole process of the exploration of the blue supergiant, gave a comprehensive introduction to all the details of the work itinerary of the scientific research fleet and the scientific research results.

"That's what we've collected at the expense of dozens of probes about the blue supergiant Cygnus P, as well as the imagery."

"And these, also sacrificed dozens of probes, but did not achieve the expected goal, and encountered an unexpected ...... in the process of approaching the diamond planet."

Wang Yao explained in detail while showing and sharing the data with everyone.

"I actually encountered an unknown cosmic civilization again!!"

"Moreover, the other party's scientific and technological strength is far superior to ours!"

"Thank you, God, for allowing you to return safely."

......

After learning about the beginning and end of scientific research and exploration, everyone sighed.

"This time, we were fortunate enough to hear and witness the magnificent wonders of the universe, but we were also met with a potential crisis. Although it was difficult and dangerous, he was fortunate to be blessed and finally returned safely. This time, whether it is at the scientific level or in the category of cosmic cognition, it can be regarded as a great gain. Yuan Haochen concluded.

"Let's not talk about the diamond planet, with this data on Cygnus P alone, we can get a first glimpse of a blue supergiant star and the secrets of a quasi-supernova."

As a subordinate, the scientific commander Don Quixote, who had just woken up from hibernation, hurriedly nodded in agreement.

"Cygnus P is very likely to create a supernova explosion in the future, and although it has nothing to do with us here, it will definitely affect our children and grandchildren. Therefore, it is necessary to find out the condition of this blue supergiant in advance! Don Quixote continued to ponder and spoke.

"From the preliminary data, the impact of Cygnus P on the Somnichi galaxy is very limited. However, if we can figure out the mechanism of supernova explosions, then we can give early warning and solve a lot of potential troubles. ”

Yuan Haochen slowly recounted that at this moment, he recalled that the former earth civilization was helpless in the face of the supernova explosion of the star WR104.

Supernova explosions are one of the most violent forms of star death in the universe. When the star that caused the supernova explosion dies, it can leave behind a neutron star or even a black hole.

Of course, stars like the stars Sunrise and Sun are certainly not qualified to trigger a supernova explosion.

Depending on the mass of stars, life can range in length from the most massive stars being only a few million years old to the least massive stars being trillions of years longer than the age of the universe. All stars are born from the collapse of gas and dust commonly known as nebulae or molecular clouds.

The evolution of a star's life is largely governed by the law that most of the star's life span is spent in a state where nuclear fusion produces energy. Under high temperature and pressure, the fusion reaction of the core of the star gradually changes the elements that make up the star, from hydrogen fusion to helium, then from helium fusion to carbon, then oxygen, and continuous fusion to form heavier elements until iron is formed.

All in all, the evolution of a star must end with one of three possible cooling states: white dwarfs, neutron stars, and black holes.

Stars such as the Sun, starting at the core, fuse hydrogen into helium in layers of spherical shells. This process causes the star to gradually increase in size, passing through the subgiant stage until it reaches the status of a red giant.

When a star like the Sun runs out of fuel in its core, its core collapses into a dense white dwarf, and the outer layers are driven away to become a planetary nebula.

While the universe is not old enough for the lowest-mass red dwarfs to evolve to the end of their lives, stellar models suggest that they will gradually brighten and heat up before depleting the hydrogen fuel in their cores, and then incarnate as low-mass white dwarfs.

Stars about 10 times the mass of the Sun or heavier, such as Cygnus P, explode into supernovae when its lacklustre iron core collapses into a very dense neutron star or black hole.

"Although dozens of probes were sacrificed, we were able to get a closer look at the outer layer of the blue supergiant Cygnus P, and extrapolated to verify the efficiency and progress of the nuclear fusion reaction inside. These are helpful in judging the further life evolution of Cygnus P. ”

Although the probes of human civilization cannot penetrate deep into Cygnus P, Wang Yao and other scientists are quite satisfied with the data collected by the blue supergiant.

"According to current data, Cygnus P has at least 1.5 million years to live." Yuan Haochen has already come to a conclusion through data analysis.

According to the analysis of the data model, after another 1.5 million years, at the very core of Cygnus P, it will fuse to form iron, and at that moment, her life will come to an end.

Instead of releasing energy, iron fusion absorbs it. Because the core of Cygnus P loses the energy support released by the nuclear fusion reaction, the outer structure of the star will be compressed by the huge gravitational pull and quickly fall towards the core.

The release of terrifying energy caused by the sudden collapse will instantly blow the blue supergiant to pieces, and only the part of the core that has been squeezed into a neutron star or black hole can continue to exist, and other stellar matter will be violently thrown into space with the supernova explosion.

During this explosion, it is possible to affect the star Sunrise, after all, Cygnus P is only a little more than 3,000 light-years away from the Sunrise galaxy.

"That's right! Will the super-cosmic civilization hidden in the Cygnus P system also follow the example of the Tata civilization and use supernova explosions against us!! ”

As a military man, the deputy military commander Hallelujah was always more sensitive.

"Although it is too complicated to deal with human civilization in this way, it is not impossible for you to deduce!" This question has been considered by Yuan Haochen before, "Although the lifespan of this blue supergiant star is still 150 years, it is very likely that a super cosmic civilization will master the ability to detonate a supernova in advance." However, at present, the axis of rotation of Cygnus P is not aligned with the Cygnus Galaxy. ”

"Then, we should always pay attention to Cygnus P's every move!"

"Yes! We must leave some means of observation around this blue supergiant and warn of it by means of faster-than-light communication. ”

"Although human civilization has long since changed from what it used to be, and has extremely strong interstellar travel capabilities, if you are not adequately prepared, you may still be caught off guard and suffer heavy losses!"

......

Everyone expressed their opinions with deep concern.
