Aurora borealis displaying vibrant teal and emerald green streaks across a night sky. The aurora fills the upper half of the image, flowing in and out of the frame. A river, with a smooth, turquoise-blue surface, meanders through a landscape of dark, basaltic rocks and snow-capped mountains at the bottom of the image. The mountains are a dark grey-brown and the snow is a muted white. Star trails, subtle and faint, are visible across the aurora. The lighting is dramatic, with the aurora as the primary light source, painting the scene in a cold, ethereal glow while highlighting the textures of the water, rocks, and mountains. The overall atmosphere is peaceful and awe-inspiring, suggesting a remote, wintry landscape.
