   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.

   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 ...

   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

   Did Venus have a liquid ocean?

   • NOT ALWAYS HELLISH Venus is completely uninhabitable now. But simulations suggest that early in its history the planet had a liquid ocean. Venus may have been all wet early on. New simulations suggest that if the now-hellish planet had just the right amount of cloud cover, carbon dioxide and water to start with, Venus could have formed an ocean.

   Could Venus have formed an ocean?

   • New simulations suggest that if the now-hellish planet had just the right amount of cloud cover, carbon dioxide and water to start with, Venus could have formed an ocean. The result, published online July 18 in the Journal of Geophysical Research: Planets, provides a new clue to whether Venus could have ever supported life.

   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.

   How much water would Venus need to form its own Ocean?

   • With carbon dioxide similar to current levels, early Venus would need only 10 percent of the mass of water in Earth’s oceans to form its own watery surface. Changing the reflectiveness of the clouds and a few other factors shows Venus would need, at most, 30 percent of the mass of water in Earth’s ocean to form its own ocean.
