White Dwarfs Pause Their Cooling, Giving Planets a Second Chance for Habitability
When a star like the Sun dies, it puffs away its outer layers, leaving behind its glowing core. Without fusion to keep it heated, the white dwarf slowly cools down over billions of years. Astronomers have discovered that 6% of massive white dwarfs pause their cooling for up to 10 billion years, providing a stable habitable zone for any planets nearby. This gives life a long time to develop under extremely stable conditions.
