Overview

  • NASA's James Webb Space Telescope has captured new images of Uranus, revealing its rings, moons, storms, and a seasonal polar cap in unprecedented detail.
  • The images show Uranus' dim inner and outer rings, including the elusive Zeta ring, the faintest and closest to the planet.
  • Webb also imaged many of the planet's 27 known moons, some of which are located within the rings.
  • The images reveal a seasonal north polar cloud cap, which becomes more prominent as the planet's pole begins to point toward the Sun, approaching its solstice.
  • The data from these images will be invaluable for planning future missions to Uranus and for studying similarly sized exoplanets.
