is expected in roughly five billion years.
These are astronomical timescales far beyond the existence of modern human civilization.
The research is therefore about understanding the long-term evolution of planets and stars, rather than predicting an imminent disaster.

Earth’s environment depends on a delicate balance between the Sun, atmosphere, oceans, geology, and living organisms.
As the Sun becomes brighter, this balance will eventually be disrupted.
