- 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.
Of course if you care to look carefully, and sometimes closely.
