"As the sun becomes a red giant, the habitable zone will move to around Jupiter and Saturn's orbit, and many of these moons will become ocean planets," Zhang said. "I think, in that case, humanity ...

Discover what will happen when the sun dies, from its red giant phase to its final transformation — plus why we don’t need to worry for billions of years.

In about 5 billion years, our sun will become a red giant, puffing up and expanding as it releases layers of material and likely evaporating the solar system’s inner planets, although Earth’s ...

As the star expands to become a red giant, its decreasing mass will force planets to migrate to more distant orbits, offering Earth a slim opportunity to survive farther from the sun. Eventually ...
