In the search for extraterrestrial life, in addition to Mars, there is another planet that has also attracted the attention of scientists, that is, Jupiter's moon - Europa. Pen, fun, pavilion www. biquge。 info

Europa is slightly smaller than the Moon and is the second closest moon to Jupiter. We currently know that there is also a lot of water on Europa. However, because Europa is far from the Sun, its surface is covered by a 3-kilometer-thick layer of ice, and liquid water can only exist under the ice. At such a deep bottom of the ice, sunlight does not shine, and it is difficult for plants to photosynthesize. Previously, for this reason, it was thought that there could be no life on Europa. However, microorganisms and fish-like creatures living in underwater cities have been found in the deep sea, where the sun does not shine。。。。。。

As a result, scientists began to speculate that there was likely life in the water beneath Europa's ice. Yes, the probability of the emergence of advanced organisms in the solar system other than the Earth is very low. However, outside the solar system, there may be more advanced creatures. Since the universe is infinite, there are so many stars and planets, and several of them have a similar environment to the earth, and are home to all kinds of life, which is very possible. We haven't found them because we haven't found them yet, and the creatures there don't have enough advanced science and technology to connect with us。。。。。。

If the planet is very close to the star, because it receives too much energy from the star, it will form a high temperature, and the water will be evaporated; If you are too far away from the star and receive too little energy from the star, it will form a low temperature, which will freeze the water, and it will be difficult for the liquid water that gives birth to life to exist. For planets to form an environment for life to exist, they must be at a moderate distance from the stars. This area is called a "livable area". The earth is able to nurture life precisely because it is in habitable areas. Of course, it's not enough to have a habitable area, you also need to have the right gravity and magnetic field.

At the end of 2250, the Mars Space Launch Station released information that their spacecraft had found an Earth's "brother" outside the solar system, the "Green Man 2" in the Sirius region, which was the first extrasolar home planet confirmed by the Mars Space Launch Station, and the smallest and most Earth-like planet of all habitable planets discovered so far. It is like the second Earth in the universe. It has a pleasant temperature, not too hot and not too cold, and has 285 days a year, which is quite similar to the earth, and not far from the North Pole there is a suitable area of lush greenery and birds. The only downside is that it is a bit far away, 6'7 light-years from Earth. Self-inventing the curved faster-than-light spaceship - we humans are cheaper than moving to other planets。。。。。。

Since Earth-like planets can be found, do highly intelligent aliens exist? No one has said yet. Human beings are also conflicted: they hope to find their "confidants" in the vast universe, but they are also worried that they are too powerful or ambitious to invade our homeland. Let's hope Lily's mysterious disappearance is just a nightmare。。。。。。

She realized that she was wrong, that she should not have retold such a profound and difficult passage of literature, that she could not understand them, that she could not understand the emotions they conveyed. Completely disillusioned with her art, she viciously threw the virtual helmet she had only used once to the floor. She figured she wouldn't be able to use it again. That piece of literature did not impress her in any way, but she remembered the author's name - Baiyun.

Lucy lay on the bed, dazed, and fell asleep very unsteadily. In her sleep, there were planets of all sizes, and it was dark space, and it was near, and it was near, and it was close, and a star rolled in, and when it rolled in front of Lucy's eyes, it stopped, and conjured up a dinosaur with teeth and claws, almost pounced on her face. Lucy woke up and couldn't continue to sleep, so she glanced at the computer screen that was still lit and wondered if she could talk to her best friend on the phone. But when she sat down in front of the computer, she didn't want to call her, so she remembered Bai Yun, and she dialed the number provided at the back of the literature. What appeared on the screen was a very handsome cosmic knight, which greatly surprised Lucy, she couldn't think of how such a mighty knight could write such heavy words, but before she could speak, the other party had already smiled brightly and said, oh, it's you, I know you. When Lucy heard this, she was completely stupid.
