New images reveal what Neptune and Uranus really look like

January 06, 2024

The single-colour images were later recombined to create composite colour images, which were not always accurately balanced to achieve a “true” colour image, and – particularly in the case of Neptune – were often made “too blue”. In addition, the early Neptune images from Voyager 2 were strongly contrast enhanced to better reveal the clouds, bands, and winds that shape our modern perspective of Neptune. This means that STIS and MUSE observations can be unambiguously processed to determine the true apparent colour of Uranus and Neptune. This revealed that Uranus and Neptune are actually a rather similar shade of greenish blue. Most recently of all, we are currently analysing the fantastic new data of Uranus from the James Webb Space Telescope.
