Study Challenges Belief That Venus Once Had Oceans
New research suggests Venus has been dry throughout its history, reshaping theories about its habitability and implications for extraterrestrial life.
- A study published in Nature Astronomy concludes that Venus likely never had liquid water, contradicting earlier theories of a wetter past.
- Researchers analyzed Venus's atmospheric chemistry, finding volcanic eruptions release minimal water vapor, indicating a dry planetary interior.
- The findings bolster the 'dry theory,' which posits that Venus was never temperate enough to host oceans, unlike the previously considered 'wet theory.'
- The study has implications for the search for extraterrestrial life, suggesting Venus-like planets may be less likely to harbor Earth-like conditions.
- Future missions, including NASA's DAVINCI and ESA's EnVision, aim to further investigate Venus's atmosphere and surface to resolve lingering questions.
