A great catastrophe awaits that will swallow the Earth! When will the sun's end be?

 

 

 

There are many arguments and predictions about when and how the end of the Earth will be. Have you ever wondered what the sun's end will be like? The answer to that question is that the sun, the Earth's star, will not end anytime soon. But like any star, the sun will have an end. The article published by Space.com provides a scientific explanation based on studies to date to the question of how the sun will end.

When will the sun's end be?

Scientists believe that the sun will disappear when the hydrogen in the star runs out. In about 5 billion years, the sun will begin to disappear as the hydrogen runs out. Scientists explain that the sun will then expand into a red giant and is likely to swallow the planets, including the Earth. But this is not something that is going to happen so quickly. The sun's red giant phase will last about 1 billion years. After this stage, the Sun will shed its outer layers and form a planetary nebula. That is, the Sun's life will end as a white dwarf star, according to researchers. When all the burning nuclear fuel is used up, the Sun will become a dead star called a white dwarf. Then the temperature in the Sun will gradually decrease and cool down. All low-mass stars end in the same way. Although the Sun is now millions of times more massive than the Earth, when it becomes a white dwarf, it will only be as large as the Earth.

The remaining inner core of the Sun will contain carbon and oxygen. Scientists also say that these are the remnants of the helium burning. If you ask what will happen to the Earth when the Sun becomes a white dwarf, or at the end of the Sun, there is an answer to that too.

If the Sun runs out of hydrogen, so will the Earth...

When the Sun runs out of hydrogen, it expands into a red giant. At this stage, the hydrogen around the Sun will be converted into helium. Scientists warn that as a result of these processes, the Sun will double in size and it is likely to swallow the planets, including the Earth. Due to this excessive heat generated in the Sun, the surface temperature of the Earth will rise. The oceans and other bodies of water will evaporate, making the planet uninhabitable. The increasing heat will also cause atmospheric gases to spread into space. Such changes may be dangerous for the existence of life on Earth. The increasing heat and radiation may lead to the extinction of most living things. Apart from Earth, the same effects will occur on other planets in the solar system, especially Jupiter, Saturn, Uranus, and Neptune. The end of the Sun will also be the end of the solar system.
