Antarctica's claim to having the bluest sky in the world may be a matter of fact rather than perception.
When it comes to the hue of our atmosphere, scientists point to Rayleigh scattering as the primary culprit behind the blue we see. This phenomenon affects light most at its blue end of the spectrum, rendering white sunlight as just that β blue. However, other factors like humidity, dust, smoke, and pollutants come into play by scattering light across a wide range of wavelengths, resulting in an off-white or milky tone that can be seen over vast areas.
But what sets Antarctica apart from other contenders vying for the top spot? Experts say it's a combination of high altitude and near-perfect conditions. With humidity at its lowest ebb and pollution levels virtually non-existent, the atmosphere is crystal clear β allowing the blue to shine through with an intensity that leaves onlookers awestruck.
Comparisons are drawn between Antarctica's neighboring regions, such as Chile's Atacama Desert and Tibet's Tibetan Plateau, both boasting impressive altitude and arid landscapes. However, when it comes to a thorough global survey of the world's skies, researchers have yet to pinpoint an exhaustive study that definitively crowns one place above the rest.
Despite this lack of conclusive evidence, Antarctica remains the reigning champion of blue skies, with visitors consistently remarking on the striking sapphire hue that envelops the frozen continent. Whether or not its status as the ultimate blue sky destination is truly objective, one thing is clear: when you're in Antarctica, the view is always breathtakingly blue.
