Scientists have discovered a “mini solar system”, 2545 light-years away from the earth, with eight planets

The solar system is not only the home of the earth, but also the home of human beings. With the development of science and technology, the exploration of the universe has finally come true. However, in front of the vast universe, the earth and human beings are too small to go out of the solar system for exploration with human science and technology.

Fortunately, the power of science and technology is powerful. Scientists have invented a powerful astronomical telescope. With its help, although we are still unable to get out of the solar system, we can see the distant depths of the universe and see many galaxies, stars, planets and so on.

The universe is vast and vast. The Milky way is only one of the countless large galaxies, and the solar system is only one of the galaxies with a galaxy coefficient of 10 million. The difference between the solar system and the earth is the birth of the planet of life, as well as the birth of human civilization. Therefore, although the solar system is small, it is a special civilization Galaxy in the universe. Because of the birth of human beings, the solar system has been upgraded to an extraordinary civilization galaxy.

So are there any galaxies in the Milky way that are very similar to the solar system? Scientists speculate that there should be galaxies very similar to the solar system, or even galaxies exactly the same as the solar system, which is the same as the existence of alien civilization. Although human beings have not found any extraterrestrial life and alien civilization, scientists never doubt its existence.

In order to explore the exoplanets, scientists launched the Kepler space telescope in 2009, which is the first space telescope in the world to detect the earth like planets outside the solar system. Using the space photometer developed by NASA, we can observe the brightness of 100000 stars in orbit around the sun, and detect whether there is the phenomenon of planetary transit.

Since the Kepler space telescope was put into use, many earth like planets and various planetary systems have been discovered for mankind. The galaxies or planets discovered by Kepler space telescope are named after Kepler. Among the many extrasolar systems discovered by Kepler space telescope, one galaxy is very special, which has attracted great attention of scientists.

This galaxy is called kepler-90. It’s about 2545 light-years away from the earth. What’s special about this galaxy? It turns out that it is very similar to the solar system, which is called “mini solar system” by scientists. Kepler-90 galaxy is also a single star system. It also has a yellow dwarf star very similar to the sun. This yellow dwarf star has the same size, temperature and mass as the sun, and even the spectrum is of the same G type, which is a copy of the sun.

In addition to having stars very similar to the sun, the galaxy also has eight planets, including rocky planets similar to earth and gas giant planets similar to Jupiter and Saturn. Many people may have to ask, this “mini solar system” is so similar to our solar system, is there a life planet like earth?

After Kepler space telescope discovered this galaxy so similar to the solar system, scientists were also very excited. However, through further observation of the telescope, we found that although there are eight planets and rocky planets in this galaxy, they are all closer to the main star. In this case, the temperature of the planet’s surface is very high, and there is no suitable temperature, There would be no liquid water on the surface of a planet, even a thick atmosphere, and life would not be born.

Of course, the above observations on this mini solar system are only the preliminary observations and analysis of Kepler. As the Kepler space telescope announced last year that it had run out of fuel and officially retired, the observation of kepler-90 galaxy has also been temporarily suspended. However, scientists will launch more advanced space telescopes and observe kepler-90 Galaxy in the future.

Although the Kepler telescope has only found eight planets in this galaxy, it does not mean that there are only eight planets in this galaxy. There may still be undiscovered planets, but due to the technical limitations of the Kepler telescope, it is difficult to observe them. If there are more advanced astronomical telescopes in the future, other planets may be found in this galaxy, even in the habitable zone An earth like planet highly similar to the earth.

If new earth like planets are found in the habitable zone of kepler-90 Galaxy in the future, the possibility of life is very high. We should know that the main star of this galaxy is too similar to our sun. If there are earth like planets in the habitable zone, the possibility of atmosphere and liquid water is also very high, and the possibility of natural birth of life is also very high It will be much higher.

Although the living conditions of extraterrestrial life may be completely different from that of earth life, it is undoubtedly a very good and correct direction to search for extraterrestrial life according to the earth’s ecological environment. The ecological environment of the earth gave birth to life and human beings, so the possibility of the birth of life and civilization will be much higher for the planet with very similar ecological environment in the universe and the earth.

Kepler-90 galaxy is the first planet very similar to the solar system discovered in the universe. I believe there will not be many such galaxies in the universe. With the rapid development of human science and technology, more advanced telescopes will be able to find more galaxies similar to the solar system in the future, and even wait for the speed of human spaceships to improve by leaps and bounds, We can also go out of the solar system to survey the earth like planets that are very similar to the earth. Maybe we will make a major discovery.
