     • However, such studies proved that the liquids would only have lasted up until 700 million to 750 million years ago, before eventually evaporating as Venus’ atmosphere heated up from the greenhouse effect.

   Studies have proven that Venus needed liquid water three billion years ago to be able to have such high concentrations of water-related minerals and gases on its surface and in its atmosphere today. However, such studies proved that the liquids would only have lasted up until 700 million to 750 million years ago, before eventually evaporating ...

   Dec 18, 2008 · Earth’s atmosphere and oceans contain 100 000 times the total amount of water on Venus. In spite of the low concentration of water on Venus Delva and colleagues found that some 2x10 24 hydrogen nuclei, a constituent atom of the water molecule, were being lost every second from Venus's day-side.

   How much water did Venus lose in the past 4 billion years?

   • According to research presented by Moa Persson of the Swedish Institute of Space Physics (IRF), Venus actually retained most of its water over the past 4 billion years. Contrary to what researchers previously thought, Venus lost only a small amount of its water to a runaway Greenhouse Effect.

   Does Venus lose water?

   • The research team said that Venus could actually have larger amounts of the molecule in its atmosphere than previously estimated. And the study results show that it would best explain the water loss. In addition, the molecule may also be responsible for Mars losing much of its water as well.

   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.

   How much water did Venus get?

   • Prior studies suggest that both Venus and Earth likely received similar amounts of water early in their history, mostly from water vapor-spewing volcanoes and icy comets that frequently bombarded the worlds. Estimates suggest Venus once had enough moisture to cover its surface in about 1.8 miles (3 kilometers) of water.

   Why does Venus have no water?

   • The new study suggests that a simple molecule, formyl cation, or HCO+, may be to blame for Venus’ lack of water. HCO+ is an ion made up of one atom each of hydrogen, carbon and oxygen. If it exists on Venus, it is high up in the atmosphere. So why would HCO+ cause water to escape Venus’ atmosphere?
