The study reveals the similarity between Uranus and Neptune

Often appearing in images with completely different hues, the true colors of Neptune and Uranus may be more similar than previously thought, a new study has found.

The first detailed images of the two ice giants at the outer edge of our solar system were made possible by NASA's Voyager 2 mission, which flew by Uranus in 1986 and Neptune in 1989.

Voyager 2 remains the only spacecraft to fly by both worlds.

Uranus appeared to be a pale cyan color, while Neptune was depicted as a gorgeous deep blue. Voyager 2 captured images of each planet in separate colors, and the single-color images were combined to create composites. Images of Neptune were enlarged to show the white clouds and winds of the planet's atmosphere.

"Although Voyager 2's popular images of Uranus were released in a form closer to true color, those of Neptune were actually stretched and expanded, and therefore artificially made too blue," said Patrick Irwin, a professor of planetary physics at the University of Oxford and author of a new study about imaging.

The corrected images show that Neptune and Uranus have a similar blue-green hue. Both planets have atmospheric fog, but Neptune looks a little bluer because it has a thinner layer of fog.

The team's results and the new image, published Thursday in the Monthly Notices of the Royal Astronomical Society, not only address a long-standing question about the ice giants, but they pave the way for a better understanding of the enigmatic planets, they say. researchers./ CNA
