Venus may have been inhabited for 3 billion years before the mysterious climate change



Hell's planet Venus may have had a perfectly habitable environment for 2 to 3 billion years after the planet was formed, suggesting that life would have enough time to appear there, according to a new study.

In 1978, NASA's Pioneer Spacecraft Venus found evidence that the planet once had shallow oceans on its surface. Since then, several missions have explored the surface and atmosphere of the planet, revealing new details about how it has transitioned from a "Earth-like" planet to the hot, hellish place it is today.

It is believed that Venus may have been a moderate planet hosting liquid water for 2 to 3 billion years before the massive recovery event of about 700 million years ago triggered the greenhouse effect, which caused the planet's atmosphere to become incredibly thick and hot.

Researchers at NASA's Godard Space Research Institute have shared a series of five simulations that show what the environment of Venus would look like based on different levels of water coverage.

All five of the simulations suggested that Venus could maintain stable temperatures ranging from a low of 68 degrees Fahrenheit (20 degrees Celsius) to a high of 1

22 degrees Fahrenheit (50 degrees Celsius), for about 3 b "Summer years," according to a statement from the Europlanet Society.

"Our hypothesis is that Venus may have had a stable climate for billions of years," said Michael Way, one of the study's researchers, in a statement. "It is possible that the global resurrection event may be responsible for its transformation from a Earth-like climate to the hellish hot house we see today."

Under stable climatic conditions, Venus could maintain liquid water and possibly allow to make life appear. In fact, if the planet did not survive the resurrection event, it could still be habitable to this day, the researchers said.

However, the occurrence event triggered a series of incidents that led to the release or exceedance of carbon dioxide in the rocks of the planet. As a result, the atmosphere of Venus became too thick and hot for life to survive.
