NASA claims – Venus planet was habitable three billion years ago, know why the situation changed

Washington, Pret. Scientists believe that water was also present on the planet Venus three billion years ago, but due to the dramatic changes in the universe 700 million or 700 million years ago, 80 percent of the planet’s area was rebuilt.

The study by the US space agency NASA revealed this. The researchers said that this study gives a new view of the history of Venus’s climate and hopes that life chances in exoplanets (outer planets of the solar system) like Venus. May occur.

Shallow ocean water may

Forty years ago, NASA’s Pioneer Venus Mission found in a study that a planet close to Earth may have shallow ocean water.

To see if Venus’s climate is such that there could ever be water, the NASA Goddard Institute for Space Studies (GISS) researchers in the US created a series of different levels of water in Venus through simulations, called five. Divided into parts.

Venus too must have been suitable for life

In all five scenarios, he found that for nearly three billion years Venus was able to keep its temperature constant between a maximum of 50 ° C and a minimum of 20 ° C.

Researchers say that this means that Venus too may have been suitable for life at some point, but even today the temperate climate can be maintained here.

Venus heats up due to turmoil

GISS researcher Michael Way said ‘We estimate that Venus would have had a stable climate for billions of years. It is possible that the climate of this planet has become warm due to the turbulence in the universe millions of years ago.

In the study, researchers found that the topography of the planet Venus was found to be exactly the same as the shape of the planet today in three out of five scenarios.

Scientists estimate that it may contain ocean water at a depth of 310 meters, shallow water layer at a depth of 10 meters, and even a small amount of water in surface soil.

The researchers also compared their results to the topography of the Earth and the position of its oceans. Venus is the second closest planet in the solar system. However, many researchers believe that being near the sun may not be a habitable possibility.

Solar radiation is twice that of Earth

Michael Way of GISS said that Venus already has twice as much solar radiation as Earth. Still, studies show that Venus is likely to have water on its surface.

He said that Venus was also hot at the time when the planet was formed around 420 million years ago, but it cooled down rapidly and carbon dioxide dominated its atmosphere.

If Venus also takes as long as the Earth to cool down, it is possible that the planet’s carbon dioxide would have been pulled by silicate rocks and life here would have been possible today.
