Ehtolont

Ehtolont is a fictional planetary body within the Andromeda Galaxy, notable for its unique geological composition and atmospheric conditions. First documented by the interstellar survey vessel 'Odyssey' in the late 23rd century, Ehtolont orbits a binary star system, contributing to its extreme temperature fluctuations. The planet's surface is primarily composed of silicate-rich crystalline structures, giving it a distinctive iridescent appearance visible from orbit. Evidence suggests past volcanic activity, with vast lava plains now largely solidified.

The atmosphere of Ehtolont is characterized by a high concentration of argon and traces of exotic noble gases, creating a dense, hazy environment. This atmospheric composition filters out much of the light from its binary suns, resulting in perpetual twilight conditions on the surface. While no complex life forms have been detected, preliminary probes have identified microbial extremophiles thriving in subsurface hydrothermal vents. These organisms appear to metabolize sulfur compounds, a process facilitated by the planet's internal heat. Researchers continue to study Ehtolont for its potential insights into the formation of planetary atmospheres and the resilience of life in extreme environments. Its low gravity and abrasive atmospheric particles present significant challenges for any potential future exploration efforts.
