The aurora cascades from the upper left toward a distant horizon lit by a soft golden rim light. No people. In the foreground, a silhouette of rocky terrain and sparse glowing flora provides scale. The atmosphere is calm and ethereal, with deep black space and faint star clusters in the background.
