Why Is Neptune a Different Color? Neptune, much like Uranus, is blue because of the presence of methane in its atmosphere, and they're generally similar in many ways. So why the different color?

For Uranus, the released images are actually quite close to what we now take to be 'true' color, and we show in our paper that if the Neptune images are recombined in the same way then the disc ...

Neptune is not as blue as you’ve been led to believe, and Uranus’s shifting colors are better explained, in new research.

"Two Uranus years (one Uranus year is 84.02 Earth years), running from 1900 to 2068 and starting just before southern summer solstice, when Uranus’s south pole points almost directly towards the ...

Uranus is more reflective at these wavelengths partially because gas methane absorbs the color red and methane is about half as abundant near Uranus’ poles than the equator.

Astronomers have used telescope data to color-correct Voyager 2 images of Neptune and Uranus, revealing that the planets have a similar greenish blue hue.

To obtain true-color images of Neptune and Uranus, Irwin and colleagues turned to data collected by the Hubble Space Telescope 's Imaging Spectrograph (STIS) and Wide Field Camera 3 (WFC3).

"Although the familiar Voyager 2 images of Uranus were published in a form closer to 'true' color, those of Neptune were, in fact, stretched and enhanced, and therefore made artificially too blue." ...

Neptune has long been depicted as a deeper, darker blue than its fellow ice giant Uranus, but a new study shows that both are a similar shade of light greenish blue.

For years, Neptune was shown to be “too blue" but researchers with the University of Oxford used modeling to show Uranus and Neptune are closer in color.

Astronomers used the data to re-balance the composite color images recorded by Voyager 2 and the Hubble Space Telescope’s Wide Field Camera 3 to reveal the "true color" of Neptune and Uranus ...
