Is there life beyond the solar system? 5

My view is that the universe has the Milky Way and extragalactic galaxies, which contain countless galaxies like the solar system, and since there is life in the solar system, then there must be life in other galaxies as well.

There must be something, or what else are we looking for?

Aren't many reports confirming this?

There are many more records

There are still a lot of unsolved mysteries

There are also good xenomorphic creatures to be discovered.

There are many more phenomena.

And so many

Not to mention outside the solar system, is there no us in the solar system?

The world is full of wonders.

There must be other life in the size of the solar system

Not to mention outside the solar system.

Isn't it?

90% don't. Because there is no life in the 40 trillion kilometers that are already centered on the earth. So there's still a 10% chance that there's one.

There must be, because many meteorites have the material that makes up living organisms, and there is no conclusive evidence that there is no life other than Earth!

There should be! The universe is infinite

The solar system is only a small galaxy in the Milky Way, and the Milky Way is only a small galaxy in the universe, and it is believed that there must be other life beyond the solar system! ^

There must be life!! I'm also convinced!! It's just a matter of time!! I probably won't be able to wait!!

I think there should be! Everything! But there is still a need for scientific evidence.

There must be one, only we earthlings are too lonely in the big space.

One word: Yes.

Two words: there really is.

Three words: absolutely.

I believe in this miracle because we are a miracle in our own right.

You say there is, there is no scientific proof anyway!

It would be nice if there was, I hope it has.

At present, only life is found on Earth in the solar system, and no life has been found on other planets so far, but there is no guarantee that it will be found in the future.

Life depends on water, air, sunlight, suitable temperatures, and nutrients necessary for life to survive. In the solar system, the Earth is at the right distance from the Sun, so the light and temperature that the Earth receives during the day and at night are suitable for life. In addition, the size and weight of the earth are also very suitable for survival.

In the area where the atmosphere and the sea and land come into contact with each other, there are animals, plants, and microorganisms all over the earth, which is the circle of life matter and life activities on the earth, and we call it life. The thickness of life is about 20 km.

In the solar system, there is only life on Earth, and there are no animals, no plants, or no life on the other planets.

Why is there no life on the other planets of the solar system? This starts with the conditions of life's existence.

First of all, the existence of life needs to have the right temperature. If the temperature is too high, the movement of the atoms is too strong and it is difficult to polymerize into molecules; If the temperature is too low, the proteins and nucleic acids will freeze, and life will not matter.

From a temperature point of view, the distance between the Earth and the Sun is unique. The average surface temperature of the Earth is about 22 degrees Celsius, and most of it is suitable for the growth and reproduction of life.

Among the planets of the solar system, the Earth's closest neighbors are Venus and Mars. Venus is closer to the Sun than the Earth, and its surface temperature is about 400 degrees Celsius warmer than that of the Earth; Mars is farther from the Sun than the Earth, and the temperature on the surface is 40 or 50 degrees Celsius lower than that of the Earth, and the temperature difference between day and night is large. The other planets are either closer to the Sun than Venus or farther away from the Sun than Fire, so they do not have the temperature conditions suitable for life.

Secondly, the existence of life requires the presence of liquid water, and there is a large amount of water on the earth, and the vast majority of water is liquid. And on other planets, even if there is water, it is not liquid.

In addition, the existence of life requires an atmosphere of appropriate thickness and density to protect life from cosmic rays and provide the right amount of free oxygen. The Earth's atmosphere fulfills this condition.

Other planets such as Venus, Mars, Jupiter, Uranus, Neptune, and even Saturn's sixth moon have atmospheres, but the atmospheres on these planets or moons are almost oxygen-free, so even if some form of life may occur on these planets, it can only be extremely primitive.

Based on the above analysis, such life on Earth is unique in the solar system.

However, many people believe that in the vast desert universe, there must be celestial bodies with life, and even celestial bodies with highly intelligent life like humans.

It's entirely possible, the universe is so vast that it's not surprising that an Earth-like planet has appeared, so it's possible that this planet could also harbor life. Life requires conditions such as liquid water, air, temperature, etc. In the solar system, only the Earth can meet the living conditions of life.

After all, it is possible that these civilizations may have appeared earlier or later than us, and it is on this theory that scientists have opened the door to a new world, that is, to study our solar system and find out if such a planet really exists.

There is no second cradle of life in the solar system, and the early stage of the great reshuffle is the most fruitful time, so the formation of life and the formation of the life environment are determined in the early stage of planetary formation.

The cradle of life on earth is exactly what the earth was born as soon as it was born, three or four billion years ago, or even earlier, the environment walked step by step through the villages that gave birth to life, so there was no more drama below.

In other words, if you leave home halfway, there is no possibility of life.

As we all know, the conditions for life to arise are enough nutrients, enough temperature, a lot of water, etc.

The reason why the solar system is completely consistent is because the temperature of the sun is just right, the position of the earth is also suitable, and the position of Jupiter is also great, which can shield the earth from many dangers before life can be born.

Scientists divide the position of the inner and outer sides of the solar system according to the distance from the eight planets to the sun, and there are four planets in each of these two parts.

There are 4 Earth-shaped planets in the inner part of the solar system, and 4 gas planets in the outer part of the solar system.

Many stars in the solar system are only conditions for the existence of life, so in the future, human science and technology will develop to a certain extent, and we may be able to unravel the mystery of these stars.

Life in the solar system shares many of the same characteristics, for example, carbon-based life, which needs to breathe oxygen and liquid water.

At that time, we could explore life not only within the confines of the solar system, but also on planets outside the solar system to explore the existence of life.

Research in this area is still in its infancy and is being developed every year. For example, Enceladus and Europa, and possibly other bodies in the solar system3354.

Under a shell made of ice, the ocean of liquid water will be suitable for microorganisms or other more complex organisms. After a while, it may become easier to study the ocean beneath the surface of Enceladus, with microwave observations showing that Enceladus' South Pole is warmer than expected. The temperature began to rise a few meters below the surface.

This may indicate that the liquid water on Enceladus may be located several kilometers below the surface, hidden deep underground and inaccessible. The basic elements of the search for life are: liquid water (water must be liquid, not ice), energy, and organic matter.

These are the substances that make up our living bodies and provide us with consumption. The above three elements must be present in the environment for a long time for scientists to believe that life can grow and evolve at the moment of birth.

When studying these three elements, it was not initially believed that they would be able to exist long enough outside of Earth, or reach a large-scale existence. Why don't scientists believe it? Let's take a look at the environments of other planets.

Anyone who is even slightly interested in astronomy will know that in the solar system, except for the Earth, the other planets are either too hot or too cold, or the weather is not good, there is no water, and it is not suitable for life, let alone human beings. So are humans really lonely?

In fact, the answer is no, there are countless planets in the universe, there must be some like the earth, but those planets are too far away from us, so we focus on the stars of the solar system.

Since the probability of life on the planet is very small, scientists have set their sights on Saturn's moon Titan. Research in this area is still in its infancy and is being developed every year. For example, Enceladus and Europa, and possibly other bodies in the solar system3354.

Under a shell made of ice, the ocean of liquid water will be suitable for microorganisms or other more complex organisms.

Enceladus is Saturn's sixth largest moon, and it is known as the solar system's most likely moon for life, due to the temperature on its surface, the likely presence of liquid water and simple organic molecules. Scientists believe that 99% of Enceladus's icy surface is made up of icy water, and that liquid water is likely to be present at Nashen Tomb beneath its surface. Jupiter's moon Europa is also believed by scientists to be a potential source of extraterrestrial life, largely due to Europa's potential water and volcanic activity.

Although its surface is frozen, many scientists speculate that there is a liquid ocean beneath its surface. The volcanic activity on Europa's surface provides the heat for life, which is as important as the chemicals necessary for living organisms, and scientists believe that microorganisms are likely to live near Europa's hydrothermal vents, a feature similar to Earth's. Triton is a moon orbiting Neptune.

It is the largest of Neptune's moons, about the size of Pluto, and it is one of the coldest objects in the solar system.

After the survey of scientists, other planets in the solar system do not have the conditions for the formation of life, and the environment of these planets is too harsh.

I think it's very probable, and there may be other places within the solar system that have a reputation for life, which makes us continue to explore and celebrate the pace of scientific research.
