Sun's evolution threatens Earth and Solar System stability

New scientific research indicates that the future of the Solar System may be more chaotic and occur sooner than previously estimated. A study published in The Astrophysical Journal Letters suggests that the Sun's eventual transition into a red giant will involve irregular and episodic mass loss rather than a smooth reduction. These asymmetric ejections of material can cause gravitational perturbations that destabilize the orbits of gas giants, including Jupiter, Saturn, Uranus, and Neptune.

Regarding Earth, the Sun's evolution poses an existential threat. As the Sun exhausts its hydrogen and begins burning helium, it will expand and increase in luminosity. Within approximately 1 billion years, Earth's average temperatures could exceed 100°C, causing oceans to evaporate and creating an intensified greenhouse effect that renders the planet uninhabitable for complex life. Eventually, the Sun will shed its outer layers and end its life cycle as a compact white dwarf.
