generate an image of a breathtakingly vibrant and ethereal aurora borealis dancing across a dark starry night sky, with swirling curtains of iridescent green and blue hues that gradate to soft pink and purple towards the horizon, set against a backdrop of silhouetted trees or distant mountain ranges, with hints of snow-capped peaks or misty valleys, and a subtle, shimmering moon casting an gentle glow on the landscape.
