Photographers capture extremely unusual phenomenon – also known as red sprites – against backdrop of the Milky Way

A trio of photographers in New Zealand have captured images of “red sprites”, or red lightning, one of the rarest light phenomena in the world, in which luminous crimson flashes appear in the sky.

New Zealand photographer Tom Rae and Spanish photographers Dan Zafra and José Cantabrana set out to shoot the Milky Way over the Ōmārama Clay cliffs in the South Island on 11 October, when they chanced upon the extraordinary event.

The photographers thought they would be lucky to get clear skies that evening, but their night turned into “an unforgettable one”, Rae told the Guardian.

Cantabrana suggested they might be treated to a display of red sprites, when he saw a storm brewing over the horizon, Rae said.
