The eventual death of the Sun might prompt humanity to search for new homes in other star systems.
The Sun provides light and warmth, as well as conditions necessary for the existence of life on the planet Earth. But it will not live forever. Scientists have previously said that the Sun will begin to die in about 5 billion years when it runs out of hydrogen, after that it will expand into a red giant and potentially engulf the inner planets, including Earth, Space.com reported.

The process of the Sun's transformation into a red giant would bring extreme heat to the outer planets, which would make them habitable. However, this phase would last only a few hundred million years.
