French scientists suggest that humanity on Earth will only live for about a billion years.
French astronomers, using new data from the Gaia space telescope, have mapped the life of the Sun and how its story will end. This was reported by ScienceAlert.
To find out the chronology of the life of a star in our galaxy, experts looked for stars like the Sun. Thanks to this, scientists received a detailed chronology of the life of the Sun.
It is noted that the age of the Sun is approximately 4.57 billion years. The surface temperature of our star is 5.5 thousand degrees Celsius.
As for the future history of the star, it will look like this:
-
Over the next few billion years, it will continue to warm. This is because the Sun’s brightness increases by about ten percent every billion years. The peak of the Sun’s maximum temperature and brightness will be reached when the star is about eight billion years old.
-
The nucleus begins to contract, causing more hydrogen to immediately enter the region around the nucleus, forming a hydrogen shell. In this process, the outer atmosphere of the Sun expands significantly, possibly even to the orbit of Mars, becoming a red giant.
-
Eventually, the hydrogen and helium will run out, all the outer matter will be thrown into space, forming a planetary nebula, and the core will become a white dwarf, which will take trillions of years to cool completely.
Earlier it was reported that a NASA device called SOHO, using its instruments, recorded the fatal descent of a comet on the Sun.
