ilmiéna

Ilmiöna is a fictional planet located in the Andromeda Galaxy, approximately 2.537 million light-years from Earth. It is known for its unique geological formations and a peculiar atmospheric composition. The planet's surface is dominated by crystalline structures that shimmer with an internal luminescence, giving rise to its name, which translates to "shining phenomenon" in a hypothetical alien language. These crystals are believed to be formed from a rare mineral that reacts with the planet's atmospheric gases.

The atmosphere of Ilmiöna is composed primarily of nitrogen and a significant percentage of an unknown noble gas, which contributes to the unusual light-refracting properties of the sky. This gas, tentatively designated "lumina," causes the sky to display a perpetual aurora-like phenomenon, with vibrant colors shifting and swirling. Due to this atmospheric condition, direct sunlight rarely reaches the surface, instead being diffused into a soft, ethereal glow.

Life on Ilmiöna, if it exists, is hypothesized to be adapted to these low-light conditions and the unusual atmospheric chemistry. Scientists speculate that any indigenous organisms would likely possess chemosynthetic or radiotrophic metabolisms, drawing energy from geological processes or ambient radiation rather than photosynthesis. Research into Ilmiöna is ongoing, with various interstellar probes and observatories dedicated to understanding its composition and potential for harboring life.
