A white dwarf, a dead star the size of Earth, dives into its own dust clouds every 5 hours, and then suddenly becomes clear again. This cosmic game of hide-and-seek helps us understand how planets die.
🎯 The 4.97-hour orbital period is so short that one 'year' for these dust clouds lasts less than a polar day in Murmansk.
