"New Images Unveil the Authentic Greenish-Blue Hues of Neptune and Uranus"

Recent research using data from the Hubble Space Telescope and the Very Large Telescope has revealed that the true colors of Neptune and Uranus are more similar than previously thought, both displaying a greenish-blue hue. This corrects the earlier enhanced images from NASA's Voyager 2 mission, which showed Neptune as an artificially deep blue. The study also explains why Uranus changes colors with its seasons, attributing it to the varying thickness of methane ice in its atmosphere. These findings, published in the Monthly Notices of the Royal Astronomical Society, help clarify long-standing misconceptions about the ice giants and assist in preparing for future missions to explore these distant planets.
