   May 6, 2024 · In the process, hydrogen atoms zip away and may even escape into space entirely—robbing Venus of one of the two components of water. In the new study, the group calculated that the only way to explain Venus’ dry state was if the planet hosted larger than expected volumes of HCO+ in its atmosphere. There is one twist to the team’s findings.

   May 6, 2024 · Advertisement. Together the new HCO + mechanism and the previously modeled water-loss processes could have enabled Venus to lose its water in half the time, a relatively brisk 600 million years, the researchers say. If so, Venus may have held onto its oceans until much more recently, perhaps 2 billion to 3 billion years ago.

   Dec 18, 2008 · Roughly twice as many hydrogen atoms as oxygen atoms were escaping. Because water is made of two hydrogen atoms and one oxygen atom, the observed escape indicates that water is being broken up in the atmosphere of Venus. The Sun not only emits light and heat into space, it constantly spews out solar wind, a stream of charged particles.

   Why does Venus escape water?

   • The group reports that a molecule called HCO+ (an ion made up of one atom each of hydrogen, carbon and oxygen) high in Venus’ atmosphere may be the culprit behind the planet’s escaping water.

   Did a molecule on Venus deliver water to space?

   • (Image credit: NASA/Robert Lea (Created with Canva)) What the team discovered was that a molecule called HCO+ — composed of an atom of hydrogen, an atom of carbon and an atom of oxygen — high in the atmosphere of Venus, may have been responsible for delivering the last of the planet's water to space.

   How did water evaporate from Venus?

   • Once free, the lightweight hydrogen escaped into space via a process known as hydrodynamic escape, leaving Venus without one of the two ingredients needed to form water. The process explains how most of Venus' water evaporated from its atmosphere, likely within the first billion years of the planet's history.

   Why does Venus lose so much water a day?

   • Using computer simulations, the team found that hydrogen atoms in the planet's atmosphere go whizzing into space through a process known as "dissociative recombination" -- causing Venus to lose roughly twice as much water every day compared to previous estimates. The team will publish their findings May 6 in the journal Nature.

   What would happen if hydrogen escaped Venus?

   • Once enough hydrogen escaped, temperatures could no longer rise, and the water loss would have slowed. “You can’t lose all the water to match the present-day observations,” says Michael Way, who has modeled Venus’s climate at NASA’s Goddard Institute for Space Studies. “You’re left in this conundrum.”
