After receiving the arrival of four people, Xu Mang originally wanted the four of them to start working tomorrow, but he couldn't stand the enthusiasm of these people, so he must go to the work place and familiarize himself with the working environment and work process first.

Helpless...

Xu Mang could only lead the four people to the observatory, and when they arrived at the small conference room of the observatory, Xu Mang began to explain the direction of this research and the specific tasks that needed to be completed.

"It's easy!"

"We need to have three white dwarfs compare the six diagenetic elements of the solar system's bodies, which are aluminum, calcium, silicon, magnesium, iron, and oxygen, uh... Compare the more objects in the system, the better, the Sun, Halley's Comet, Earth, Moon, Vesta, Mars, Mercury and three meteorites. ”

"There are also enstative meteorites, common L meteorites and carbonaceous CI meteorites, mid-ocean ridge basalts and hepaite. Xu Mang said seriously: "That's all for the time being, I hope to complete this work in two weeks, and then proceed to the next step of research." ”

It may be that the newborn calf is not afraid of tigers, and when he heard the task assigned by Xu Mang, he did not feel pressure, but looked forward to the arrival of tomorrow.

Liu Yan and Zhao Pengpeng were in charge of the calculations. ”

Tong Min and Lu Bo were responsible for observing and collecting data. ”

"Uh..." Xu Mang pondered for a moment and said silently, "That's basically it." ”

After arranging the task, Xu Mang forcibly let the four of them leave the observatory, although the magic capital is not far from Ning City, but Xu Mang still hopes that the four of them can take a good rest and meet the new challenges with the best spirit.

After sending Tong Min and the four of them away, Xu Mang sat in front of the computer and carefully looked at the content on the screen.

After thinking about it for a while,

Xu Mang decided to start with the debris values of these three white dwarfs and calculate some relevant data first, such as the difference between the oxygen fugitiveness of the rocky planets in the system and the rocky planets outside the system, but... There is a little error bar in three white dwarfs, such as the third white dwarf...

Relative to the uncertainty of the measurement of the star's iron concentration, the white dwarf has a very low upper limit of the obtainable value.

therefore

Xu Mang only had two samples in his hand, which was obviously not enough, but Brother Chuan Xiao found only these three... Even in the database there are very few, and by calculating... None of the white dwarfs in the database can be used as data samples.

Finished...

What the hell is going on?

Xu Mang thought about it for a long time, and finally made a phone call to Professor Smith on the other side of the sea, and it seemed... It was night over there, and I guess Professor Smith wasn't asleep.

Passed.

"Hello?"

"Professor Smith... It's me. Xu Mang smiled and said, "You... You're not busy right now, are you?"

"Hmm!"

"Xu Mang, do you have anything to do?" Professor Smith received a call from Xu Mang and asked with a smile: "If there is anything to say directly, there is no need to be polite to me." ”

"Uh..."

"Mainly, I'm a little embarrassed. Xu Mang said embarrassedly and politely: "I want to borrow Princeton's astronomical database, and I want to know some data on white dwarfs, in terms of quantity... Of course, the more the merrier. ”

Hearing Xu Mang's request,

Professor Smith was silent for a moment, then said seriously, "Actually... In principle, no. ”

At this point,

Xu Mang showed a hint of a smile.

"I'm going to have someone give you access to the server remotely. Professor Smith said, "But... Don't spread the data around, Xu Mang... It's not a joke, you have to keep it a secret. ”

"Huh?"

"This..."Xu Mang was stunned for a moment, if the data is not disclosed, wouldn't this be a tragedy?

originally

Xu Mang plans to use hacking technology to hack the database of Princeton University, but after all, it is the crystallization of human wisdom, and it is a bit irresponsible to do so.

"Are you studying something?" asked Smith curiously.

"Yes!"

"A revolutionary discovery!" Xu Mang said with a smile, "If there are no accidents... With the help of the platform of the Princeton Astrophysical Society, I would like to reveal to the world a secret that can shorten the process of human migration to space. ”

Professor Smith was stunned for a moment, and couldn't help but smile bitterly: "In that case... Then go public, you are a full member of the Princeton Astrophysical Society anyway. ”

"Hmm. ”

"Then it's a happy decision!" Xu Mang said with a smile.

Then

Professor Smith said: "One thing I want to communicate with you is that Princeton University wants to grant you the status of a professor, and you don't need to take classes, only honors. ”

"Oh..."

"I don't have a problem. Xu Mang said indifferently.

"When the time comes... When you have a press conference, I'll give you the certificate. Professor Smith said.

"Okay. ”

subsequently

The call was interrupted, Xu Mang looked at the mobile phone call interface and sighed helplessly.

Another professorship...

soon

Xu Mang logged in to his account on the official website of the Princeton Astrophysical Society and found a large number of white dwarf data from the database.

Then Xu Mang was stunned...

"I..."

"What should I do?"

"Are you looking for them one by one?" Xu Mang slid the wheel, and his scalp was numb in dense English, although English was not a problem, but... But with so much English, the head is easy to explode.

Thinking about it,

Xu Mang decided to hand over these contents to Tong Min and a few others to complete, anyway... I can't do it myself anyway.

...

Following

Tong Min and Lu Bo got up early, washed up briefly, and then left the hotel and went straight to their place of work, after all, the first day of work needed to leave a good impression on Professor Xu.

Sadly, however, the two stood in the doorway and found the door locked.

"We seem to have come too early. Tong Min said.

“...”

"I'll just say it!" Lu Bo smiled bitterly: "How can you start working at six o'clock, usually eight o'clock or half past eight." ”

Then

Liu Yan and Zhao Pengpeng rushed over and found Tong Min and Lu Bo standing at the door, and the four of them stood at the gate stupidly, looking at the time... It's half past six.

"Huh?"

"Yesterday I looked it up... It seems like a lot of work. Zhao Pengpeng said: "I'm afraid... I'm afraid I won't be able to do the job. ”

"What are you afraid of!"

"I think Professor Xu is very good at talking, not the kind of person who makes a little mistake and kicks his nose in the face. Tong Min said: "Anyway, he gives me a good feeling, but this game is too good... OMG... It's just for nothing. ”

Speaking of games,

Tong Min and Lu Bo looked helpless, and Professor Xu wanted to open the black... It's really going to great lengths, and he directly built a black group, and there were four people in it.

Every night open a handful of black,

Then send!

"Anyway..."

"Professor Xu's wife, let's call it a wife. Lu Bo said curiously: "This temper seems to be quite hot... Especially when playing games, as long as Professor Xu gives away heads, he will be sprayed by his wife. ”

“...”

"I guess this kind of character can suppress Professor Xu. Tong Min said: "Terrifying!"

Liu Yan: ???

Zhao Pengpeng: ???

Is it so scary?

People have to be quiet, uh... may have been forced by Professor Xu last time.

Long

When the four of them were about to hold on, Xu Mang rode his Ducati to the gate of the observatory, facing this great scientist who kept up with the fashion trend, and had some cognitive changes in his impression of the professor and the so-called scientist.

Composed...

Professor Xu is so cool?

To the lounge,

Xu Mang said with a smile: "Don't be so early in the future, you will make me embarrassed." ”

“...”

“...”

“...”

A few people did not speak, and Professor Xu's glorious image was gradually collapsing.

After a brief break, the official work begins.

According to the needs of the mission, Tong Min and Lu Bo are looking for those diagenetic elements in the intrasystem planets, as well as all kinds of messy data, but according to Xu Mang's own estimates, it will take at least four or five days, just to use this window period to let Liu Yan and Zhao Pengpeng find suitable samples in the data of white dwarfs.

Before, there were three samples, but after their own calculations, they became two samples, which is too little... Lack of contrast.

It seems to be a tall job, but behind it is the accumulation of countless hours of boredom and sweat, after three days of work, Xu Mang secretly observed the state of the four people, quite serious.

Seemingly...

The time could be shortened a little longer.

NASA，

Habitable Planet International Joint Exploration Office,

In addition to NASA and ESA in the United States, this is an international research group, with the Russian Federal Space Agency (RKA), the Footbasin Chicken Aerospace Research and Development Agency (JAXA), the Samba Space Agency (AEB) and the Canadian Space Agency (CSA).

The main goal of this group is to find a planet suitable for human habitation in the vast universe. Thanks to the efforts of this research team, a dozen exoplanets with potentially habitable environments have been identified.

But a new study suggests that the universe could have a staggering number of habitable planets, with more than 60 billion of them likely in our galaxy alone, essentially orbiting faint red dwarfs.

So far

This research group needs a new way of exploration, in addition to upgrading the existing exploration equipment, it needs to make new changes in theoretical research.

However...

When the technology was upgraded and the theory was advanced from the original to the latest concept, scientists discovered that every red dwarf should be surrounded by an Earth-sized planetary body located within the habitable zone.

While red dwarfs are the most numerous and common type of stars in the universe, therefore... The number of habitable planets has doubled again.

However, under such difficult conditions, several planets have been found that are most similar to Earth in terms of environmental conditions so far, and if we judge by the Earth similarity index, Earth is 1 and Mars is 0.7, then these planets are about 0.9.

But...

There is a huge controversy within this research group about the planet.

Followed by

The national members of the international research group began a competition to explore new theories.

thereinto

The progress of ESA is most obvious, using the concept of gravitational microlensing, which is intended to explore terrestrial planets, a technique that is simple enough to magnify the object behind it as a lens when a planet or star moves in front of another distant star.

This is how ESA uses this phenomenon to develop new technologies for detecting unknown planets.

basically

In this internal international competition, ESA ESA has won, at least that's what ESA's scientists think.
