Act as a visionary sci-fi concept artist with 10+ years of experience in extraterrestrial landscapes. Create a hyper-detailed, surreal depiction of an alien volcano erupting with bizarre, otherworldly colors. The scene should feature [vibrant neon lava] cascading down jagged [crystalline rock formations], while the sky is filled with [bioluminescent ash clouds]. The atmosphere should feel both awe-inspiring and eerie, with strange alien flora reacting to the eruption. Use a mix of deep purples, electric blues, and fiery oranges to emphasize the unnatural beauty of this alien phenomenon. The composition should be dynamic, with a sense of scale that makes the viewer feel tiny in comparison to this cosmic event.
