Can the prestigious solar system be spared? Can the earth be spared?The answer may be thoughtful

Astronomers saw the end of the solar system!

The life and death of a star and the planets around them. This picture uses the solar system as an example to describe how a solar star with planets around it is born, runs, and dies. We can distinguish between seven stages that have been completed or still need to be completed, such as synthetic images and English comments.

Sometimes near the center of the galaxy, there is a dying star -white dwarf, a giant walk star runs around it. For astronomers, they look very similar to our solar system. Once our sun burns all fuels, it will become like this. Exciting!

There are many scammers who claim to see the future. But this time, those serious astronomers proposed to leap time and move towards the future: in order to see what the future of our solar system will look like. Please rest assured that they have not invented the time travel aircraft. They just discovered a planetary system, and its evolution seemed to be exactly the same as the forecast of the fate of the solar system -about 5 billion years later, when our sun reached the end of its life, it would show.

Through the gravitational lens effect (when the stars close to the earth and the more distant stars occur instantly), scientists have discovered a giant planet, which is about 40%larger than Jupiter. Surprisingly, when scientists were looking for its central celestial bodies, they found that the brightness of the central celestial body was not enough to become the main preface star said by astronomers.

In this picture, the artist's idea of ​​the end of life of a main stars: it first became a red superstar, and then collapsed into a white dwarf. A Jupiter's giant giant rotation is rotated in the distance, survived in this explosive transition.伦 Adam Makaronko, Kay Observatory

The data quickly ruled out the possibility of brown dwarfs, neutron stars and even black holes in the central celestial body of this giant exterior planet. Then there is only one possibility that this wooden walking star must be run around a white dwarf. A stars that die. Located near the center of the galaxy.

Jupiter may be able to survive

Keep in mind that when a main stars, such as our sun, have burned all the hydrogen in its core, it will go through a "red superstar" stage. Then it collapses and reduces it until it becomes a white dwarf -a hot, dense star residue. The white dwarf is about the size of the earth, but the quality is twice the earth! It is difficult for astronomers to observe this residue because the light of white dwarfs is very weak.

A newly discovered wood -type outer planet is running around a white dwarf -a dead star. For astronomers, the system is similar to our solar system when we swallow the last breath.

Researchers' discovery proves that planets running far away from the center of the center are likely to survive after the star "death". "Therefore, Jupiter and Saturn can escape the destruction of the end of the life of the sun. The future of the earth is even more uncertain, because our planets are closer to the sun." China pointed out, "If humans want to move to a Satellite or Saturn's satellite before the red superstar stage of the sun swallowing the earth, we will still live on the orbit around the sun. Although once the sun becomes a white dwarf, we will no longer rely on the sun The heat survive. "

Researchers hope that Nanyi Grace-Roman Space Telescope, which will launch in 2025, hopes that it can get more information about such planetary systems. The main task of the infrared telescope is to directly imagine giant exogenous planets. By studying the planets running around white dwarf stars in the center of the galaxy, the telescope should make astronomers determine whether the type of wooden stars escape from its stars' death is common, or most of the planets are destroyed when the stars are becoming a red superstar.

"Fitella in the Starry Sky" is a must for astronomy and space enthusiasts. On the 1st of each month, please join us to make a complete view of the Monthly Star calendar and get the suggestions of how the best observation of things in the starry sky. Special programs published on the 15th of each month will provide you with more opportunities to learn more about a specific thing or event in astronomical and space news.
