Antarctica’s sky dazzles in shades of purple after Tongan volcanic eruption

Months after the Tongan volcanic eruption, the Antarctic sky has turned stunning shades of purple and violet due to the afterglow from the powerful eruption.

Following the volcanic eruption, aerosols made up of sulphate particles, sea salt and water vapour circulated in the air, bending and scattering sunlight and creating a glow in the sky with hues of pink, purple, violet and blue.
