Things dont look so good long term.
"Our Sun is about 4.57 billion years old. About half way through it's life. The Sun will slowly turn into a red giant in about 4.5 billion years and about two billion years later, it will shed it's outer layers and become a white dwarf. For the Earth, this means that when the Sun turns into a red giant, the Suns envelope will expand until it nearly touches the Earth.
For life on Earth, it's not as simple, in about a billion years time, the Sun will have increased it's temperature to such a degree that it will be impossible for life to exist on the surface as it would have become so hot that all water would have boiled away."
