volcano Tonga still causing impacts around the world months after the eruption, and now scientists who are working on Antarctica took stunning pictures of the icy sky of the continent, which are its reflection.
As A photo were taken by New Zealand Antarctica technical scientist Stuart Shaw, who is stationed at Scott Base during the winter.

“Typically in the middle of winter in Antarctica it is almost always dark, with the exception of a slight “nautical twilight” around noon, which means that the horizon is faintly visible in good conditions. But this year we were treated to a real show where most of the station staff grabbed their jackets and ran outside with their cameras to see amazing colors. Believe it or not, I haven’t edited these photos either, they are very similar to the ones we saw. It’s amazing,” Shaw said. NIVA.

Shaw reportedly shared the footage after seeing stories of the pink sky phenomenon happening in New Zealand due to aerosols left in the stratosphere from the Tonga volcano eruption in January, which made him realize the same thing was happening in Antarctica.
According to Nava Fedaeff, NIWA meteorologist, satellite data indicate an abundance of aerosols in the stratosphere at an altitude of 15 to 24 km above Antarctica, which were not present before the Tonga eruption.
“Stratospheric aerosols can circle the globe for months after a volcanic eruption, scattering and bending light as the sun sets or rises below the horizon, creating a glow in the sky with shades of pink, blue, purple and purple,” the meteorologist explained. “This volcanic twilight is known as a ‘glow’, with color and intensity depending on the amount of haze and cloudiness in the path of light reaching the stratosphere.”
These aerosols are usually sulfate particles, but since the eruption occurred underwater, it is possible that there are water vapor droplets as well as sea salt. This is the same phenomenon as caused changes in the sky also here in Brazil.

Jordy Hendricks, Chief Scientific Adviser for Antarctica New Zealand, commented on the phenomenon. “Nature never stops putting on a show in Antarctica, and it can be beautiful or destructive,” he said. “These photographs capture the wonder it causes and how our planet is connected. Antarctica is about 5,000 km from New Zealand and about 7,000 km from Tonga, but we share the same sky.”
“What happens in Antarctica affects us at home and vice versa,” he continued. “Much of the science we support is focused on understanding these dynamics in the atmosphere, oceans and ecosystems and helping to better understand the connection between Antarctica and Earth. New Zealandand the whole world.”
