From the Alt Description (see 2nd pic, right side)
"Vibrant green and purple auroral lights illuminate a dark night sky filled with stars. The lights form wavy patterns and curtains across the horizon. A dark foreground suggests a flat landscape like a field or tundra. No people or structures are visible. The overall scene conveys a serene natural spectacle."
