Neptune's Vanishings Clouds Linked to Solar Cycle.

  • Neptune's clouds have diminished and mostly disappeared from 2019 to 2020.
  • This is likely due to increased UV radiation from the Sun evaporating the clouds.
  • Neptune receives only 0.1% of the sunlight Earth gets, so it's surprising it is affected.
  • There appears to be a correlation with the 11-year solar cycle, which impacts the Sun's emissions.
  • More studies are needed to understand the Sun's effects on all planets in our Solar System.
