KEY HIGHLIGHTS
- A plume of ash and dirt unleashed by the Tongan volcanic eruption induced the afterglow.
- Scientists in Antarctica noticed the atmospheric phenomenon beforehand reported in Oceania.
- The sky over the Scott Base on Ross Island, Antarctica was bathed in hues of pink and purple, due to this afterglow.

The Polynesian underwater volcano erupted on January 15, sending shockwaves throughout the Pacific ocean. It unleashed what was doubtless the tallest plume of ash, sulphur dioxide and steam ever recorded, rising 58 kilometres.
Aerosols from the volcanic plume had been dispersed across the globe, due to the colossal drive of the January explosion “lots of of instances” extra highly effective than the Hiroshima and Nagasaki atomic bombs.
Now, scientists have put the purple and pink color of the twilight sky down to those aerosols’ interplay with gentle.

Researchers in Antarctica reported their observations to New Zealand’s Nationwide Institute of Water and Atmospherics (NIWA) after experiencing the phenomenon within the southernmost area of the world.
Why did the skies over Antarctica flip purple?
This produces a superb firework of colors often called an “afterglow”. The volcanic twilight, as seen over Antarctica, is the truth is a generally occurring impact within the wake of an eruption. The color and depth of this alpenglow is decided by the quantity of haze within the sky, based on Fedaeff.
These volcanic aerosols can linger round within the environment for about two years.
“Nature by no means fails to placed on a present in Antarctica, and it may be lovely or harmful”, Antarctica New Zealand’s Chief Science Advisor Jordy Hendrikx mentioned in an announcement.
“These images seize the awe it evokes, and the way linked our planet is. Antarctica is a few 5,000km [3100 miles] from New Zealand, some 7,000km from Tonga, however we share our skies.”
