"Scientists Uncover 'Fountain of Youth' Phenomenon Extending Stars' Lifespans by Billions of Years"

Scientists have discovered a population of white dwarfs that appear to have stopped cooling for billions of years, defying the classical understanding of these stellar remnants. A team of researchers has proposed a mechanism behind this phenomenon, suggesting that some white dwarfs generate energy through the formation of solid crystals that displace liquid material, releasing gravitational energy and halting the cooling process. This discovery challenges the way astronomers date stars and may redefine our understanding of stellar evolution.
