Northern and southern auroras often mirror each other
Aurora borealis and aurora australis are twin responses to the same solar wind hitting both magnetic poles — so bright shows in the Arctic often have a matching curtain over Antarctica.
Earth’s magnetic field funnels particles into oval rings around each pole. Satellites and linked cameras have watched the two ovals light up nearly in sync.
Two skies, one driver. Polar light is a global system wearing local colors — green, red, and purple on opposite ends of the planet.
