Life on Earth: Much important information received about the sun, life will not be possible on earth

It is a known fact that the source of life on earth is the sun. The light and heat from the sun make life easy here. In such a situation, if someone says that there will come a time when the sun will swallow the earth, then it will be difficult to believe. Astronomers studying different stars say that about five billion years from now, the sun will start swallowing its planets. However, it will take more than a thousand billion years for the sun to end. Much important information about the sun has been received from the data received from the Gaia spacecraft sent by the European Space Agency. Along with this, research is going on for a long time in the universe about such stars, which start swallowing their planets.

The life of the sun rests on hydrogen

The source of the Sun's energy is the hydrogen present in it. Nuclear fusion of hydrogen produces energy on the Sun. The Gaia spacecraft has collected data related to hundreds of stars. Analyzing these, estimates are being made about the Sun. Researchers say that by the age of about 8 billion years, the temperature of the Sun will be at its peak. From then onwards the hydrogen will gradually decrease and the temperature of the Sun will start falling.

increases in size

What kind of star will behave, it depends on its size and mass etc. When there is a shortage of hydrogen on the Sun, then its size will start expanding. Its size will become hundreds of times larger. Such stars are called red giants. For the first time, about a century ago, scientists came to know about the Red Giant stars.

Stars become man-eaters

In the solar system, the planets revolve around the star. In this process, the planets are bound by the gravitational force of the star and they also get energy from the same star. As a star turns into a red giant, its planets merge into it. Such stars are called cannibal stars.

life will not be possible

Ricardo Yarza of the University of California, Santa Cruz, said that it is not yet clear whether the sun will swallow our earth, but it is certain that life will not be possible here. It is also necessary to know about this deeply so that human society is prepared that there will come a time when it will have to leave the earth.

A new world is formed after the destruction

Not every planet that orbits a star is destroyed. Some large planets also form the basis of the new system.

Yarza and his colleagues have created a model that analyzes the appearance of giant planets in stars.

Sometimes a giant planet breaks away from the star and makes a new orbit for itself. The results of some models suggest that planets orbiting in new orbits sometimes become the medium for the formation of new worlds.
