Scientists have figured out how and when the sun will die.

Experts from the European Space Agency have analyzed new data from the Gaia Optical Space Telescope. Thanks to them, scientists were able to determine how the Sun will develop in the future. According to calculations, our star is already 4.57 billion years old, and in general it is still stable. However, eventually the star will die - the process will begin when the core runs out of hydrogen. The merger process will begin, which will turn the Sun into a red giant star and lower the surface temperature by dozens of times. In this state, it will last another thousand billion years, until it turns into a dim white dwarf. But it is unlikely that a reasonable form of life on Earth will catch this - the brightness of the Sun increases by about 10% every billion years, which entails an increase in temperature. Such changes will make our planet uninhabitable long before the end of the solar system.
