   Aug 11, 2016 · Measurements by NASA’s Pioneer mission to Venus in the 1980s first suggested Venus originally may have had an ocean. However, Venus is closer to the sun than Earth and receives far more sunlight. As a result, the planet’s early ocean evaporated, water-vapor molecules were broken apart by ultraviolet radiation, and hydrogen escaped to space.

   Aug 11, 2016 · Research Features NASA Climate Modeling Suggests Venus May Have Been Habitable. August 11, 2016. Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to 2 billion years of its early history, according to computer modeling of the planet's ancient climate by scientists at NASA's Goddard Institute for Space Studies (GISS) in New York.

   Did Venus have water oceans in its distant past?

   • Observations suggest Venus may have had water oceans in its distant past. A land-ocean pattern like that above was used in a climate model to show how storm clouds could have shielded ancient Venus from strong sunlight and made the planet habitable. Credits: NASA

   Was Venus habitable?

   • There are still two major unknowns that need to be addressed before the question of whether Venus might have been habitable can be fully answered. The first relates to how quickly Venus cooled initially and whether it was able to condense liquid water on its surface in the first place.

   Did ancient Venus have an Earth-like atmosphere?

   • That means an ancient Venus with an Earth-like atmosphere could have had the same rotation rate it has today. Another factor that impacts a planet’s climate is topography. The GISS team postulated ancient Venus had more dry land overall than Earth, especially in the tropics.

   Is Venus too close to the Sun?

   • Although many researchers believe that Venus is beyond the inner boundary of our Solar System’s habitable zone and is too close to the Sun to support liquid water, the new study suggests that this might not be the case. “Venus currently has almost twice the solar radiation that we have at Earth.

   Could Venus still support surface temperatures amenable to liquid water?

   • However, in all the scenarios we have modeled, we have found that Venus could still support surface temperatures amenable for liquid water,” said Way. At 4.2 billion years ago, soon after its formation, Venus would have completed a period of rapid cooling and its atmosphere would have been dominated by carbon dioxide.

   Sep 22, 2019 · Forty years ago, NASA ’s Pioneer Venus mission found tantalizing hints that Earth’s ‘twisted sister’ planet may once have had a shallow ocean’s worth of water. To see if Venus might ever have had a stable climate capable of supporting liquid water, Dr. Way and his colleague, Anthony Del Genio, have created a series of five simulations ...
