live techno Stars have several stages of life before they finally die. Our Sun will continue to heat up over the next few billion years until it eventually runs out of hydrogen to fuse at its core.
The nucleus will begin to shrink, a process that brings more hydrogen into the vicinity of the core, forming a hydrogen shell. This hydrogen then begins to fuse, dumping helium into the core in a process called shell burning.
The Sun’s outer atmosphere would expand, perhaps even orbiting Mars, turning it into a red giant. Eventually, the Sun will run out of hydrogen and helium, ejecting all of its extraneous matter to form a planetary nebula.
According to Page, the core will collapse into a white dwarf, which takes trillions of years to cool completely. science alert Monday, August 15, 2022.
The end time of a star’s life depends on the individual characteristics of each. The best way to find them is to search the Milky Way for Sun-like stars at different stages of life, then piece them together into timelines that model the past and future.
With the release of the latest data from the European Space Agency’s Milky Way Galaxy Mapping Project, the most detailed timeline of the Sun’s life is known.
Gaia’s primary mission is to map the galaxy with the highest degree of accuracy, and is equipped with a suite of instruments for the task. It tracks the position and movement of stars in the sky, giving a detailed overview of each star’s brightness and spectral classification.
