The Death Star, whose name was ruined by Yuan Shichen and the others, is not far from the Sand Star.

Its orbit is smaller than that of Sand Star (Alpha Centaurus B1), and its positional relationship within the star system is like the distance between Venus and Earth.

Since the distance is close to the alpha star b (star), it can be imagined that the temperature of the dung star is higher than that of the Sand star. According to their calculations, the average temperature on the surface is expected to be between 150 and 200 degrees Celsius.

Due to its close distance, the Future spacecraft did not turn on its speed too high and planned to reach its destination after one Earth day

On the way, Harashi Chen and Lin En made full use of their time to study all biological samples collected on the Sand Star in a special isolation laboratory.

Nei Chen and Lin En are not considered experts in the field of biology, but they certainly do not lack basic scientific literacy, so there is no problem in carrying out some basic research projects.

After about 10 hours of hard work, Harashichen and the others finally had some preliminary understanding of the life system of Sand Star.

Alien organisms in a broad sense refer to life matter that exists on the planets outside the earth. They include the simplest most basic amino acids, proteins, and some unknown bacteria. Of course, the highest-level alien intelligent organisms are the aliens that everyone calls them.

After research, Yuan Shichen and his team further confirmed that the life forms on the Sand Star have many commonalities with the earth.

"Do you think the Sand Star is not the main star of the birth of the Creator civilization?" Lin Neng discussed with Harashi Chen while analyzing the research results.

"I am quite sure of this. With the environmental conditions of the Sand Star, it is indeed difficult to create a highly developed civilized world. It should be just a resource planet." Yuan Shichen said affirmatively.

"Although the current environment of Sand Star is relatively harsh, maybe it was not what it was today 2.1 billion years ago." Lyn guessed.

"No, the orbit of the Sand Star 2.1 billion years ago was closer to the B star than it is now. Therefore, the ecological environment of the Sand Star at that time would only be more severe than it is now. Even so, I believe that the birth of life on the Sand Star must also be related to the Creator." Harashihara added.

"Indeed, whether it is a plant or a microbial sample, the organic matter composition they contain is basically the same as the Earth."

“The main difference in existence is genetic material.”

Through super electron microscope, Haraki Chen and Lin Neng discovered that Sand Star's biological genetic factors are completely different from those of the Earth.

They do not use DNA or RNA as genetic material like Earth organisms.

However, their genetic material still belongs to the category of nucleotides, and can be regarded as a class of heterogeneous nucleic acids (xna). Biologists on Earth have also discovered and artificially synthesized heterogeneous nucleic acids (xna) with similar structures.

The xenogenic nucleic acid xna of the genetic material contained in Sand Star organisms is similar to DNA and RNA in the function and structure of synthetic nucleotides, except that they replace the deoxynucleic acid and ribonucleic acid in DNA and RNA with different substances.

This type of xna is also replicated by polymerase-like molecules. Like DNA and RNA, they can also interpret, copy and convert nucleotide sequences.

"I guess that 2.1 billion years ago, the Creator sent the [Source of Creation], which was loaded with various organic matter, genetic material and other raw materials to the primitive earth. After a long period of time, the earliest raw materials for genetic material gradually changed during the evolution of nature, and then they embarked on a development direction similar to the Creator's world but not exactly the same." Yuan Shichen guessed thoughtfully.

"What you said is very likely." Lynn agreed.

"As for other amino acids, purines, pyrimidines and other organic compounds are different from genetic materials, because their species are diverse and do not involve the mechanism of genetic replication, so after the birth of the earth's organisms, they still use these biological raw materials to form their bodies." Hamasaki added.

In fact, humans have detected hundreds of organic molecules such as formaldehyde, ethanol, amino acids, etc. outside the earth. Therefore, various organic molecules are not rare in the universe.

"Since that's the case, we have a problem, and we must consider it carefully." Lin En said with a deep face.

"Are you referring to food?" Yuan Shichen asked back.

"That's right."

"During the exploration of the Centaur Alpha Galaxy, at least now we have solved the problem of drinking water and oxygen supply." Harashi Chen said with a smile, and it can be seen that he is still optimistic about the acquisition of survival materials.

"Do you think we can directly use the plants on the Sand Star as food? Or do we need to use the natural environment of the Sand Star to grow crops on the earth." Lynn asked bluntly.

"this"

Yuan Shichen smiled slightly and then began to think about this issue seriously.

As the saying goes, people regard food as the most important thing, and eating is the eternal pursuit of life.

When humans arrive at the alien habitable ball, replenishing the granary in time is definitely something that must be done to explore aliens. As the saying goes, "If there is food in the warehouse, you are not panic." Catching a sheep on the earth to make a roasted whole sheep is delicious, but if you catch an alien sheep, do you really dare to slap?

Whether alien creatures can eat depends on what they are made of.

Although the creatures of Sand Star are like the creatures on Earth, they are nucleic acid/protein organisms with water as the medium, but their actual composition is different. Even the creatures on Earth cannot digest them all, such as the enoki mushrooms with the famous "color e, lure, torro" (see you the next day).

Therefore, when you get to aliens, you will definitely not be able to catch whatever you see or eat whatever you catch.

Although the plants on the Star of Sand are also rich in carbohydrates and other nutrients needed by the human body, what Haraki and Linen are most worried about is that they are different from those of the earth's creatures.

In theory, because the digestive system of Earthlings does not contain the degradation enzymes of specific XNAs of Sand Star, these XNAs will not be absorbed and excreted from the body after passing through the human digestive system. However, it cannot be ruled out that XNAs may also obtain genetic information from specific RNAs and DNAs and cause damage to them.
