The sun, despite emitting no perceptible odor on Earth, releases volatile organic compounds (VOCs) and terpenes that can potentially interact with olfactory receptors. These compounds, along with ozone in the atmosphere, may contribute to the faint yet distinct scent astronauts report when exposed to the solar environment. The specific nature of this scent remains enigmatic, and further research is needed to fully understand the olfactory responses to the sun’s emissions.
