Wait, you mean there's life on Europa?

Professor Naduo's electronic voice using mechanical synthesis also showed his surprise. He looked around and looked at the people panting. Everyone nodded like a chicken running through broken rice, but couldn't say a word.

"It's strange..." Professor Naduo began to stroll around the bridge with his hands on his back. "We haven't seen any traces of organisms in our long observation at such a close place to the earth. The oxygen on Europa is so thin that we shouldn't have the conditions to adapt to biological evolution."

"However, with oxygen and water, it already has the conditions for basic organisms to survive... Even if it is a little worse, there are alpine regions on the earth. Aren't there large animals like polar bears living well?" Lele interrupted many professors' thoughts.

"Also, my main consideration is that the oxygen on Europa is not made by organisms, and its atmospheric composition is not suitable for biological survival. However, it is difficult to say whether there will be other organisms under the ice. If we can find large carbon based organisms here, it will be an additional harvest!" Professor Naduo became more and more excited.

"Could it be a higher intelligent creature?" Jia Jia asked.

"It should not be. The first feature of any higher creature is to transform the environment. The environment here is so primitive that there is no trace of man-made transformation."

"The animals we see seem to be dead!" Hao Zhi said. "They don't move like chickens and fish frozen in the refrigerator."

"In any case, immediately start the investigation, excavate the biological traces under the ice, and bring back some samples in the shortest time, whether dead or alive!" ordered Professor Naduo.

"Yes!"

The unexpected harvest made everyone very excited, so all preparations were immediately carried out. Ice drills and drilling trucks were sent out at the same time, stopped digging for three days, and began to dig near the hole where organisms were found.

Tons of huge ice were dug out and dragged to one side to build an ice tower as high as a mountain. It was not until it was dug 20 meters deep that a clue gradually emerged.

In this eternal frozen world, there are creatures!

Unfortunately, it's all bodies!

While excited, everyone seemed a little disappointed, but they carefully dug out the body of one of the animals along the outline. The lifting frame lifted the huge animal like a rhinoceros, slowly placed it on the truck and pulled back the spacecraft.

"Don't bring back the main body of the spacecraft, just put it in the outer cabin!" Professor Naduo shouted to the people outside through the microphone, "we don't understand the characteristics of organisms in the world. Once frozen, there may be unexpected microorganisms that may threaten the lives of the crew, so you don't have direct contact with the specimens!"

Sitting on the high ice, Hao Zhi suddenly had an ominous feeling in his heart. Then he looked back into the ice pit. The dazzling bright sun behind just shone into the ice pit and reflected all kinds of miscellaneous shadows

This is a world of death!

Hao Zhi shivered and suddenly realized that there might have been a prosperous biosphere on this planet, but they all died at a certain time, and then all were frozen

Anyway, this is a very bad signal!

Everyone was busy working, holding the lifting truck with all hands and feet, placed the huge animal body on the platform, then entered the disinfection room, carefully cleaned up the spacesuit, and then returned to the main bridge one after another.

"Everyone is working hard!" the professor smiled and signaled. The machine service platform sent a piece of food. Everyone was hungry. They each picked up their plates and ate.

"Professor!" Hao Zhi looked at the picture on the monitor. "What is this animal? It looks like a pig, mixed with hair, but it's quite big!"

"In any case, it must be an alien creature. It's definitely not the same kind as the pigs on earth, and I don't know if I can eat..." the guy with the nickname "bold son" certainly interrupted. His ancestral home is also Shanxi. He is known as the son of the tomb robbing family. He stole someone's grave with his parents since childhood. Because the tomb path is very narrow, he went into the grave alone to steal things when he was five or six years old, So he got the nickname and loved to tell ghost stories, claiming that nothing could scare him.

"I don't eat that!" Lele almost gushed out the rice after hearing him say so.

"This needs to be dissected before we can confirm whether it is a system with the creatures on our earth. At least from the appearance, it is very close! After all, we belong to the same star system habitable zone and are close relatives."

Habitable zone of star system? The two miners, the second soldier, asked at the same time.

"For example, the sun is a star, an interstellar unit in the universe. In terms of system, the smallest unit is centered on the star. Some stars are lonely, and some have planets. Like our sun, we live with nine little brothers around us. These nine stars rotate around it at different distances, and their energy and sunlight nourish these nine Little brother... "Professor Naduo, considering the other party's incomplete knowledge, can only explain it to them with a more simple and straightforward explanation.

"Oh..." the two understood.

"We all know that the basic living conditions of carbon based organisms such as earth creatures are sunlight, water and oxygen. With these three conditions, the planet is suitable for the evolution of higher life. However, with different energy levels of a star itself and different distances from its planets, some suitable organisms will be formed, while others are not.

For example, mercury, which is too close to the sun, although its name is mercury, in fact there is no drop of water. It is too hot and it has all dried up. Pluto, which is too far away from the sun, is too weak to get heat when the sun reaches there. Therefore, it is almost a dark and frozen world. More than 100 degrees below zero, water is frozen into dead ice pimples

Therefore, there will be no living things when they are far or near. Only a planet like the earth, which is just near the sun, can freeze in winter, can swim in summer, can exchange energy between oceans, rivers and the atmosphere, and give birth to the whole ecological cycle, can form a complete life system.

The planets near this position are called the habitable belt of the star system... "

"Oh! Key business circle!" the two twin soldiers laughed, and then stared and asked Professor Naduo, "I've never had fun. Please ask you a question..."

Professor Naduo was surprised. These two old-fashioned eggs still have scientific questions to ask themselves. It seems that they are really eager to learn.

"Please say..."

We have been flying so high and so far. What we always want to ask is, where do the Tathagata Buddha and the jade emperor live?
