Uranus and Neptune Closer in Color Than Previously Thought, New Images Reveal

Reprocessed Images Using Hubble and Very Large Telescope Data Correct Previous Misconceptions, Explain Seasonal Color Changes in Uranus

New images reveal that Uranus and Neptune, the ice giants of the solar system, are closer in color than previously thought, both appearing as a lighter blue-green hue.
The images were reprocessed using data from the Hubble Space Telescope and the Very Large Telescope, correcting the artificially enhanced blue color of Neptune in previous images.
The original images of the planets were taken by NASA's Voyager 2 spacecraft in the 1980s.
The study also explains why Uranus changes color slightly during its 84-year orbit of the sun, appearing a touch greener during its summer and winter solstices.
The researchers attribute this color change to a 'hood' of icy methane increasing the reflection at green and red wavelengths at Uranus' poles.
