Neptune and Uranus seen in true colours for first time
www.bbc.com
Analysis shows that our ideas of the colours of the planets Neptune and Uranus have been wrong.

  • Previous images of Neptune and Uranus, particularly from Voyager 2, were inaccurately blue and green due to image processing for detail enhancement.
  • New research analyzed data from Hubble and VLT telescopes to reveal their “true” colors are both a similar shade of greenish-blue.
  • Neptune still has a slightly bluer tinge due to a thinner haze layer.
  • Uranus may appear slightly greener in summer/winter but bluer in spring/autumn due to its unique tilt.
  • This research corrects a long-held misconception about these distant planets.
