NASA just dropped a wild timeline: Earth becomes uninhabitable in the year 1,000,002,021. That's roughly 1 billion years from now. Before you panic, here's what's actually happening — it's not asteroids we should fear, it's the sun itself.

Our star is slowly getting hotter and bigger. Eventually, it'll boil Earth's oceans dry and turn our planet into a barren wasteland. The process is already underway: climate change and global warming are basically early warning signs.

Short-term threat? Solar storms. NASA flagged these in 2024 — massive bursts of solar energy that mess with our atmosphere and spike planetary temps.

The plan B? Mars. SpaceX and Elon Musk are betting humanity's future on becoming multiplanetary. Artificial habitats with controlled everything could work, but it'll take insane funding and centuries of development.

Bottom line: We've got breathing room, but the decisions we make today determine if we actually survive that far. Pretty wild when you think about it.
