Can life survive in the solar system once the sun dies and becomes a red giant star? New research suggests there may be a narrow window of possibility for life to persist on the icy moons of the outer solar system.
It's not exactly clear where the habitable zone of the red giant sun will be, but it could possibly reach the orbit of Jupiter. Although the planet itself won't be habitable because it will still be a giant ball of hydrogen and helium gas, Jupiter's moons might become promising homes for life.
