The sky in Antarctica turned shades of red. Pictures with an unusual phenomenon were published by Stewart Shaw from New Zealand, who is located at Scott Base in Antarctica..

“Typically in the middle of winter in Antarctica it is almost always dark, except for a slight “nautical twilight” around noon, which means that the horizon is faintly visible in good conditions.. But this year we got a real show where most of the station staff grabbed their jackets and ran outside with their cameras to look at the stunning colors.. Believe it or not, I did not edit these shots either, they are approximately the same as we saw them.. It's incredible,"

The National Institute of Water and Atmospheric Research of New Zealand (NIWA) explained the unusual phenomenon with the eruption of the Tonga volcano, which occurred in January. Before that, an unusual pink sky was observed in New Zealand itself..

NIWA forecaster Nava Fedaeff said satellite lidar data show an abundance of aerosols in the stratosphere at an altitude of 15 to 24 kilometers above Antarctica, which were not there before the eruption..

Stratospheric aerosols can circulate around the globe for months after a volcanic eruption, scattering and bending light as the sun dips or rises above the horizon, creating a glow in the sky with hues of pinks, blues, purples and purples..

This volcanic twilight is known as the 'afterglow', with the color and intensity depending on the amount of haze and cloudiness in the path of the light reaching the stratosphere,” Fedayeff added..

Aerosols are mostly sulfate particles.. However, since the Tonga eruption was underwater, it is likely that water vapor droplets and salt are present..

In early July, the sky over South Dakota in the United States turned green. Scientists have linked this phenomenon with a hurricane.
