The Mind-Blowing Rings of Saturn | The Universe (S4, E5) | Full Episode

HISTORY・2 minutes read

Saturn's iconic rings, consisting of trillions of particles moving at high speeds, are held in place by the planet's gravitational pull, constantly changing due to Saturn's tilt. Recent discoveries show Saturn's E ring is sustained by water geysers from moon Enceladus, with Saturn's rings serving as a blueprint for understanding planet formation processes in our solar system.

Insights

  • Saturn's rings, consisting of trillions of particles ranging from dust grains to house-sized chunks, are held in place by the planet's gravitational pull, forming a vast, wafer-thin plane that spans 180,000 miles in diameter.
  • Recent discoveries indicate that Saturn's E ring is sustained by water geysers from the moon Enceladus, with frozen particles shooting off the moon and forming the ring, suggesting the presence of a liquid ocean on Enceladus.
