Summary:
- The article discusses the long-term future of the Sun and Earth, and how the Sun's evolution will eventually make Earth uninhabitable for life as we know it.
- As the Sun ages, it will gradually grow larger and brighter, turning into a red giant star. This will cause the Sun's habitable zone to move outward, eventually making Earth too hot to support life.
- After the Sun exhausts its fuel and sheds its outer layers, it will become a dense white dwarf star, leaving behind a lifeless, scorched Earth in its wake.
