What has changed from 1975 to 2022 in the mystery of life in the universe

From 1975 to 2022, some progress has been made in the exploration and development of the "mystery of life in the universe".

In 1975, the puzzle focused on the question of whether there was life beyond Earth. However, with the advancement of science and technology, our understanding of life in the universe is also increasing.

Especially in recent decades, astronomers and biologists have discovered a number of conditions that may support the existence of life. For example, scientists have found similarities between Mars and Earth, but have yet to find signs of life. At the same time, we have also discovered some planets outside the solar system, which are called "habitable zones" because their conditions may be suitable for the existence of life.

In addition, we are also beginning to study biomolecules in the universe, which may be the building blocks of extraterrestrial life. Although we have not yet directly discovered extraterrestrial life, these discoveries have given us a deeper understanding of the possibility of extraterrestrial life.

Overall, from 1975 to 2022, our understanding of life in the universe has deepened, but whether we can find definitive evidence of the existence of extraterrestrial life remains an unsolved mystery.

The mystery of life in the universe after 1975 is: "whether there is life beyond the earth", which is the mystery of life in the universe that human beings have been exploring.

Humanity has yet to find another planet with life. Mars, the only possible life on Earth, has unraveled the mystery with the rapid development of space technology. Scientists have found that Mars has many similarities to Earth, but there are no signs of life yet.

This remains the mystery of life in the universe.

Hello friends, during this time, the biggest contribution to the discovery of the universe is the discovery of black holes, and a picture of a black hole, and the rest is the discovery of many stars, planets and other celestial bodies, thank you.

2.The largest galaxy.

3.The fastest stellar orbital period.

4.The fastest meteorite.

5.The coldest star.

6.The oldest celestial bodies.

7.A planet with chemical signs of water molecules.

Is there any alien life in the vast universe? Why don't scientists dare to reveal the truth?

We live on the earth, maybe many people think that our earth is really too big, because if you want to go to a city, or go abroad, to the other side of the earth, it takes several hours to get there, the earth is really too big, in fact, we are really frogs at the bottom of the well compared to the universe, the vast universe is really big we can't imagine, how to describe the size of the universe, in fact, when we look up at the stars every night, our human eyes see the stars, It's just a little bit in the solar system, the unexpectedly vast universe of the solar system, we humans can't see it with our eyes, and the largest planet in the universe that we humans know is that Canis Major VY is one of the largest stars known to mankind. If you sit on a passenger plane traveling at 900 kilometers per hour and circle the Canis Major, you need to fly for 900 years. It can easily fit about 3 billion suns.

So since the universe is so big, is there any extraterrestrial life, many scientists, believe that there is, but there is no evidence to explain at present, but the vast universe is so big, maybe our scientific level is limited, and the telescope can't see too far away, so it leads to a lot of the truth of the universe, we humans can't know it at all, sometimes it's not scientists who dare not announce the truth, but scientists don't know the truth, what to use to announce it to the public?

What do you think of the vast universe, and do you believe that there are other civilizations in the universe???

NASA launched two Viking Mars rovers in 1975. After a year-long "long journey", the probe entered the Martian atmosphere and successfully landed on Mars. The two landers carried a number of sophisticated instruments to analyze the Martian soil, and also measured the wind speed, air pressure, temperature and other indicators on Mars, and determined the composition of the Martian clear atmosphere.

Some of these experiments are aimed at detecting the presence of life on Mars. In these experiments, robotic arm excavation took samples of Martian soil and conducted experimental studies on the soil samples, which found clear proof of the release of gases from Martian soil. However, scientists at the time thought it was just a chemical reaction.

Miller's repeated study of some of the archives obtained by NASA led to a surprising result: the cycle of gas released by Martian soil is very similar to that of Earth's gas. This suggests that life may have been on Mars.

"I fundamentally believe that this is a sign of life," Miller said. ”

According to what we know so far, there is hope for life on Mars, but no life has been found yet.

Scientists have analyzed the balance in the solar system: Mercury, the closest to the sun, is too hot; Venus, lack of oxygen, lack of water, strong light exposure; Jupiter, Saturn, Uranus, Neptune, and Pluto are all far away from the Sun, and the temperature is too low. None of these planets could have life.

Mars is very similar to Earth in all aspects, but scientists have not found microbes on Mars, so further research is underway.
