What the Aurora Australis Actually Looks Like From 400 Kilometres Above Earth

From the ground, the aurora australis appears as ghostly curtains drifting across the southern sky — greens and purples bleeding into the dark like something between a hallucination and a weather event. From the International Space Station, the perspective shifts entirely.

Recent timelapse footage captured by astronauts aboard the ISS reveals the Southern Lights not as a distant spectacle but as something you are moving through. The station travels at roughly 28,000 kilometres per hour, completing a full orbit of Earth every 90 minutes, which means the aurora doesn't just sit there — it surges beneath and around the spacecraft as continents scroll past in silence below.

What produces this is not gentle. Charged particles streaming from the sun — part of the continuous flow known as the solar wind — slam into Earth's magnetosphere and are funnelled toward the poles. When they collide with oxygen and nitrogen atoms roughly 100 to 300 kilometres above the surface, those atoms shed energy as light. The specific colours are a kind of atomic fingerprint: oxygen at higher altitudes emits red, lower oxygen glows green, and nitrogen contributes blue and violet.

The aurora australis mirrors its northern counterpart, the aurora borealis, appearing simultaneously at the opposite magnetic pole — a twin event playing out across two hemispheres, largely unseen because so little land mass sits beneath the southern lights. No cities. Mostly ocean, ice, and wind.

From orbit, all of that isolation vanishes. The curvature of the planet becomes visceral. The atmosphere, which from the ground feels boundless and permanent, appears as a paper-thin luminous skin wrapped around the Earth — and the aurora burns within it like something alive.
