Green Earth Aurora | International Space Station

NASA astronaut Don Pettit: "Green auroras stretching as far as the eye can see, almost mistakable for another planet rather than the blue Earth we call home."

Auroras happen when charged particles from the Sun interact with Earth's magnetic field, creating dazzling light shows in the sky. Auroras occurs in an upper layer of Earth’s atmosphere called the ionosphere.

This image from low-Earth orbit was captured by experienced NASA astronaut and former Expedition 71/72 flight engineer, Don Pettit.
