Venus and Earth: How Venus lost its water….what was the main culprit
About 4.5 billion years ago, Earth and Venus were similar in size and structure, likely possessing equal amounts of water.
However, Venus has transformed into a barren desert with high atmospheric pressure and sulfuric acid clouds, almost devoid of water.
Recent research suggests that the Methanaldehyde ion (HCO+) may be responsible for this transformation, evaporating water into space.
Planetary scientists from the University of Colorado at Boulder discovered that HCO+ could be a key factor in Venus’s arid conditions.
Initially, Venus likely lost water through atmospheric evaporation, exacerbated by its exposure to the solar wind, unlike Earth protected by its magnetic field. This loss over billions of years may have led to Venus’s current water scarcity.
