Sun will die in 5 billion years but life could survive on Jupiter’s moon Europa; here’s how

In approximately five billion years, as the Sun transforms into a red giant, it will engulf Earth. However, a new study suggests this event could briefly make Jupiter's moon, Europa, habitable. As the Sun's habitable zone shifts outward, Europa's icy surface may melt, potentially creating a temporary atmosphere and liquid water, offering a short window for life.
