The most distant planet in our Solar System has been the planet Neptune, which is also known as the ice giant, since 2006 after the elimination of Pluto. Surely you remember the color of Neptune from the School Atlas of the World, which has always been depicted in bright blue (perhaps even royal blue). Now, however, a team of astronomers from the University of Oxford has revealed that Neptune was depicted in the wrong color spectrum and that its color is much more reminiscent of Uranus, whose color could be compared to azure.

On the other hand, this fact is not a big surprise for astronomers. According to scientists, it has long been known that most modern images of the planets are not depicted in the correct color. The images were first taken by the Voyager 2 probe, which, according to the head of research from the University of Oxford, were "stretched and improved". In short, the contrast was changed for them to make the clouds or the movement of the winds more visible. Although astronomers drew attention to this deficiency at the time, the information disappeared from general awareness over time. Once the original data was applied to the current model, the scientists were able to display the most accurate depictions of both Neptune and Uranus. The blue coloring of both planets is then caused by a large content of methane, which absorbs green and red light.
Great and amazing images also came from WebbTelescope.
I'm sorry that all the published pictures are somehow edited or put together, that it's more like a computer animation than a photo. I would like to publish an imperfect original photo sometime. Unfortunately.
