Venus, in ancient China, there are several names, folk call it too white, but if the time of appearance in the sky is different, there are a variety of different names, such as the morning in the east is the star, when the sky is dark in the west is chang Gung star, the brightness of Venus is relatively high, so many years ago it was associated with various legends.
However, the real Venus is terrible, why do you say so? Although it has long been known as Earth's sister planet, both of which are terrestrial planets of the solar system, Venus indicates an extremely high temperature, currently recognized by the scientific community as 462 °C. Venus isn't the closest to the Sun's position, but it's hotter than the rest of the solar system, including Mercury!
It can be said that even though the Apollo series of American missions achieved manned landing on the moon more than fifty years ago, China has also made major breakthroughs in the field of space in recent years, such as landing on the far side of the moon for the first time and retrieving samples from the moon, and the Tiangong space station is also being built in an orderly manner. But even in another hundred years, let alone the United States, it is likely that any country in the world will find it difficult for astronauts to stand on Venus.
However, venus, which has such a harsh environment, still has scientists who believe that there is probably still life on this planet, especially in the clouds of Venus, but this is speculation without exact evidence.
There is a new news, and many people are excited, that is, nasa's Parker solar probe, while studying the sun, observed the rare "spectacle" of Venus, the point is that even if the clouds of Venus are very thick, the surface is generally covered, but the wide-area imager used by the Parker solar probe in the United States is based on the type of light that the human eye can see, what is going on?
Directly speaking of the results, that is, the United States, a probe that focuses on observing the sun, captured the appearance of the night on the surface of Venus through its own wide-area imager, and the dynamic pictures and images at that time have been published:
It is necessary to explain that the color shades in the view are different, and from the perspective of temperature, the light area is actually hotter than the dark area.
The scene that attracts everyone's attention is that when a bright light flashes, the glowing "object" is like a piece of iron pulled out of the forge, but this may not be necessarily related to the existence of life on Venus before, because the scientific community has explained that the reason why objects of such a shape are captured is mainly because the temperature on Venus is so high that the surface of the rock may also emit light.
Some people are worried about whether our earth will one day become the like of Venus, objectively speaking, this concern is really not unfounded, far from saying, everyone looks back at the extreme weather events that have occurred in recent years. Not to mention that we don't know, the identified mass extinction event has already occurred 5 times, which is why scientists speculate on when the sixth mass extinction will begin.
Over the years, many species have also been declared extinct, and many species are on the verge of extinction, such as the Yangtze River white sturgeon, known as the "giant panda in the water", which was officially declared extinct on December 23, 2019. Similarly, the natural tests suffered by human beings in recent years are also quite severe, the trend of global warming has not been contained, not to mention the rise of sea levels caused by glacier melting, just today's large-scale, long-lasting forest fires, ancient viruses that may be exposed after the thawing of the Arctic permafrost, in fact, it is enough to worry, many places in the summer are encountered with extreme heat, winter is facing blizzard attacks, once in a century, the floods that occurred once in a century, the year before, not to mention the virus that suddenly appeared and continued to evolve.
In the longer term, life on Earth will be in a desperate situation because of the evolution of the sun, knowing that today's sun is like a young adult, although it occasionally brings damage to the earth's infrastructure, but this is already a relatively "gentle" period.
In a few billion years, the sun will expand into a red giant, and the earth at that time, even if it is not swallowed by the sun, will become a place worse than the current Venus, at least the known life on the earth will not be able to continue to survive, and this is a gradual process, before progressing to this point, the earth life, including human beings want to survive, need to migrate to other planets.
So, although it is still very far from that day, scientists are looking for planets that may have life outside the earth, especially those that have similar characteristics to the earth, because the purpose of our exploration of other planets, including exoplanets, in addition to solving the mystery of whether there is life outside the earth, there is also an important purpose, that is, to find a second earth, after all, from the probability of life, there are so many planets in the universe, it is indeed likely that more than one planet has evolved life. Therefore, including Venus, whose environment is already so harsh, we cannot rule out the possibility of life for the time being, after all, the form of life may still be what we do not understand.
