Earth uninhabitable in a billion years, supercomputer study finds
NASA and University of Tokyo researchers predict Earth becomes uninhabitable around year 1,000,002,021 as the Sun expands.
A supercomputer combined climate modelling with biogeochemistry to forecast when Earth stops supporting life. The results point to roughly one billion years from now, when the Sun expands and heats the planet beyond where life can survive, and oxygen levels drop too low.
The exact timeline depends on how long the Sun continues to live. The research, published by Kazumi Ozaki and Christopher T. Reinhard in Nature Geoscience, notes the Sun's increased activity, solar flares and sunspots in recent months suggest the process has already begun.

Why it mattersGives a concrete timeline for Earth's far future and shows how long life on our planet may last.
AustraliaNo direct Australian effect for a billion years, but the research comes from global collaboration and helps understand our planet's ultimate fate.
