As the Sun continues to run out of fuel, the evolution of stars will gradually enter the red giant phase, and the Sun is no exception. In 4 billion years, the Sun will expand more than 50 times its current level, forming a giant red giant. At this time, the earth will no longer be suitable for life, and any life on the earth will face the fate of extinction.
During the red giant phase, the surface temperature of the Sun will decrease and become colder, but the temperature at the center of the Sun will continue to rise, reaching temperatures of more than 1 billion degrees. Such high temperatures will allow the sun to release more energy, so the sun will become brighter.
In this context, the earth will be completely unable to withstand the sun's radiation, the water on the earth will evaporate, and the atmosphere will gradually disappear. Life on Earth will not survive, and the entire planet will turn into a roasted desert.
However, in such a situation, some of the material on Earth will form a beautiful scene. Earth's rocks and dust will be blown away into space, forming a giant dust cloud. This dust cloud will reflect the sun's rays, forming a beautiful halo. Humanity will be able to observe this miraculous sight in the distant future.
In addition, the magnetic field on Earth will also be severely affected. Since the high-energy particles released by the sun can damage the Earth's magnetic field, the Earth's magnetic field will no longer exist. However, such a situation will also create some beautiful sights. The charged particles released by the sun will interact with the gas on Earth to form a beautiful aurora. This sight is one of the only beautiful sights that humanity will be able to enjoy in the next 4 billion years.
In short, in the next 4 billion years, the Earth will change dramatically, and the entire Earth will become lifeless. However, at the same time, it will also create some beautiful sights that make us feel the magic and beauty of the universe.
