Seeing Earth from outer space

Today I have brought you an article about looking at the earth from outer space, welcome to read it!

Whenever night falls, the dark sky will be dotted with stars, they are the elves in the night sky, bringing some light to the night. People in ancient times, due to the lack of astronomical knowledge, naturally did not know what those stars are. Even so, some ancient wise people still through long-term observation of the changes of the stars in the sky, explore some of the mysteries of the stars, it must be said that human wisdom is infinite.

After humans entered the age of technology, the emergence of astronomical telescopes allows us to travel through space and see distant stars, at that time we understand that the stars in the sky are sun-like stars. I believe that if such an answer was told to the ancients, no one would believe it and would treat you as a psychopath.

In the eyes of the ancients, they would never believe that the stars in the sky at night are essentially the same as the sun. Because in the eyes of the ancients, the sun is sacred, and nothing can be compared with the sun. But the real answer often exceeds people's expectations, modern science has proved to us that those stars in the sky are a star, and most of them are bigger and brighter than the sun.

When we stand on Earth and look up at the distant stars, they are so small, so small that they scare us. But when we know what they are, we are shocked, so some people ask the question: What does the Earth look like from other planets? If it was before mankind entered the age of technology, there was no answer to such a question, because we could not travel to other planets.

But when mankind entered the age of technology, with the help of technology, we finally came out of the Earth, we can also go to some other planets to explore so that we can see what our Earth is like from the perspective of different planets. 50 years ago, Apollo carried mankind to the moon, the satellite of the Earth, standing on top of the moon, we first really felt its desolation, but also saw the beautiful Earth. It was certainly a shocking and proud experience to see the Earth from the perspective of the Moon, where we saw a huge and beautiful Earth that was completely different from other colorless planets.

The Earth is so beautiful, it is like a dream planet, azure in color, and the whole Earth radiates the light of a jewel from the Moon. This charm cannot be described in words, perhaps only by actually stepping out of the Earth can you feel it. And the Moon, due to its proximity to the Earth, is the best observation point in space, where one can see a beautiful and huge planet that mankind is proud of: it is the home where we have lived for millions of years.

From Earth, we travel to Mars, Earth's neighbor, the most explored planet since humans came out of Earth, which has many similarities to Earth and is the first planet that scientists expect humans to migrate to. Standing on Mars to see the Earth is not so beautiful, many people may think that standing on the surface of Mars to see the Earth, you can see very bright blue stars.

But the real situation is not so, although the night sky of Mars also has many stars, it is difficult to distinguish which is the Earth, it is as common as many stars have not stood on the moon to see the kind of beauty of the Earth. From Mars to see the Earth is not as clear as Mercury to see the Earth, Mercury probe in 2010 in the orbit of Mercury took a picture of the Earth, apparently the distance between Mercury and Earth than the distance between Mars and Earth, but we can see darkness still exists in a larger view, it is the Earth. And next to the Earth there is a point of light, it is the Moon.

The Cassini probe once took a picture of the Earth, from which we can see a more obvious point of light, that is the Earth. This position is also the farthest we can directly observe the Earth. Further on, the Earth is already difficult to see directly.

The farthest human photograph of the Earth should be Voyager, which took a final photograph of the Earth when it traveled to the edge of the solar system. To see the Earth in this photograph, we need to magnify the Earth a few times, and only at this time can we faintly see a tiny dot, and this dot is the Earth.

Through these different planetary positions to see the Earth, so that mankind no longer has the original pride and pride, for the universe and the stars, the Earth is too small, so small that even dust can not be counted. If you stand in the perspective of the solar system, the Earth can be called a small glass ball, but if the field of view to the entire galaxy, the Earth can only be considered a grain of dust.

If you look at the whole universe, the Earth is not even a speck of dust, but at most a tiny cell in a living organism. So, when people looked at the Earth from different planets in the solar system, they were silent. Humans feel great, creating a brilliant technological civilization, but in front of the vastness of the universe, this achievement of human technology is nothing.

Humanity's current technology can not go out of the solar system, and can not explore the entire galaxy, let alone explore the entire universe. And our technology has not yet discovered extraterrestrial life and alien civilizations, some arrogant people will think that the Earth is the only living planet in the universe, and human beings are the only civilization in the universe. But most sober people understand profoundly that Earth is just one of the countless living planets in the universe, and humans are just one of the countless civilizations, and possibly a relatively low-level civilization.

In the universe, the family of civilizations, mankind has nothing to be proud of or to be proud of. We have searched for alien civilizations for more than half a century and have found nothing. But it is possible that the existence of the Earth and humans have been discovered by powerful alien civilizations, and the reason they have not yet come to Earth, is possible that they do not yet have the ability to interstellar voyage, or human strength is too weak to look up to us.

And the universe is also to follow the laws of the Dark Forest, good and malicious civilizations exist, and even within a civilization, the attitude towards Earth will be divided into two camps good and evil. Once the existence of the Earth is discovered by an alien civilization, which happens to have the ability to interstellar navigation, it is possible to come to Earth to invade us.

Some people may say, if an alien civilization wants to invade the Earth, it is only to see the resources of the Earth and the solar system, as long as we give them the resources will be fine. But in fact, the alien civilization may not see the resources of the Earth and the solar system, to know that for an interstellar civilization, there will be no shortage of resources. And in the eyes of the alien civilization, what is precious on Earth may be human beings.

Although the vast universe may have an endless number of civilizations, the number of civilizations is still too few and far between because the universe is so vast and evenly distributed. For alien civilizations, it is also a matter of luck to discover a civilized planet, and the most precious resource of a civilized planet is the intelligent life on it. So the war between civilizations, it is possible to plunder not natural resources but intelligent life resources.
