How much does humans know about the solar system?
The Earth is one of the eight major planets in the solar system, with its orbit in the third position. This position is unique and can receive an appropriate amount of solar radiation energy, so that the earth can have a relatively suitable temperature. This is also the most important condition for the birth, development and evolution of earth's organisms. The position of the earth in the solar system is the best.
The Earth has appeared more primitive life 900 to 1 billion years after its birth. After billions of years of development and evolution, although countless species extinction events have developed, millions of species still exist on the Earth today. Human beings are the pride of heaven. They rely on their smart brains to occupy an important ecological niche, develop a smart civilization, and control more resources.
With the development of human civilization, there are few no man's land on the earth. Even the highest Mount Everest and the deepest Mariana Trench have already had human footprints.
Since the middle of the last century, humans began to explore real space, and the first one to come into contact with or understand the most is of course the solar system. As an star system, it is enough to have life, not to mention that it has developed a smart civilization. We launch various probes, send astronauts into space, or even to the surface of the moon. We think we have a deep understanding of the solar system, but in fact it is far from enough.
The solar system is not just the eight planets we know. In fact, there are still a large number of celestial bodies, such as various dwarf planets , asteroids, and distant long-period comets. It may even have celestial bodies from outside the solar system. For example, Oumuamu discovered by scientists in 2017, it rushed into the solar system in a strange posture and then joined and left. Before scientists could hurry to do a deeper exploration, Oumuamu disappeared in a blink of an eye.
If Orte Cloud is regarded as the boundary of the solar system, the diameter of the solar system can reach 2-3 light years. The farthest distance that humans currently fly is the moon. 380,000 kilometers away, and the farthest probe is Voyager One 23 billion kilometers away, that's all.
In the solar system, with the sun as the center, there are also eight planets and their respective satellites , as well as asteroid belt , Kuiper belt celestial bodies, and more distant long-term cycle comets mainly gathered in the Oort Cloud.
Recently, scientists may have discovered new structures in the solar system. Because the light from all known celestial bodies was eliminated, scientists found that there were still some glows in the solar system, which were as weak as firefly in the night sky. To give a simple example, when we return home and pull up all the curtains in the room and turn off the lights in the bedroom and living room, in theory, some glow can be seen in the dark room. So, scientists still don’t know where these glows come from.
Harber Space Telescope is a telescope launched by humans onto the Earth orbit . It is not affected by ground light pollution and the earth's atmosphere, and can better stargazing.
Astronomers analyzed more than 200,000 photos taken by Hubble. They obtained data from the photos and eliminated all the light from stars, planets, galaxies, and various known celestial debris. There is still a glow in the background, emitting a faint light like a firefly. Astronomers believe that there is still a new undiscovered structure in the solar system.
So how do you determine that these faint lights do not come from outside the solar system? We know that NASA has launched a total of 5 interstellar probes so far, four of which were launched in the last century, the most famous of which is Voyager One, which has been flying for 45 years and has now been 23 billion kilometers from the earth.
There is also an New Horizons detector launched in 2006. It was used to detect Pluto . In 2015, it flew over the terrifying celestial body at close range and then continued to fly into deep space.Scientists compared some data obtained from New Horizons, which is different from those obtained by Hubble Space Telescope, which is enough to show that these faint light comes from the inside of the solar system, and even within the range of the eight planets, and will not exceed Pluto.
Some netizens began to open their minds, believing that these unknown mysterious lights may be related to alien life. Some friends think that they are smart spacecrafts from alien life. When the back of the moon was still very mysterious, everyone guessed that the alien spacecraft was docking on the back of the moon, but later found that the back of the moon was far less mysterious than everyone imagined.
is a similar conspiracy theory. It has always believed that humans are being monitored by advanced civilizations. Then the mysterious glimmers discovered by scientists are enough to illustrate the problem.
But in fact, this statement is too imaginative, scientists prefer to believe that they are an unknown new structure in the solar system, perhaps because the dust from the comet fell off, and they reflected the sun's light.
