Venus has probably been inhabited for 3B years. Then something mysterious happened.



Although Mars may have ever maintained life, Earth is the only planet in the solar system currently known. A new study, however, notes that Venus may have been inhabited for several billion years – until something mysterious happened.

A study presented at the European Planetary Science Congress – Planetary Sciences Joint Meeting 2019 notes that Venus potentially had stable temperatures and was home to "liquid water" for 2 to 3 billion years until a "dramatic transformation" happened more than 700 million years ago, which completely changed the planet and surfaced about 80 percent of it.

THE AGE OF THE FIRST OF SATURDAY CONSIDERATION AS ANIMAL ENERGY ISSUES

"Our hypothesis is that Venus may have had a stable climate for billions of years. 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, ”lead study author Dr. Michael Way said in a statement.

Returning to the present day, Venus has a surface temperature of 864 degrees Fahrenheit. However, in the five results Way and the researchers conducted for the study, they found that Venus was able to maintain stable temperature scenarios between minus 20 degrees Celsius (-4 degrees Fahrenheit) and 50 degrees Celsius (122 degrees Fahrenheit) for about 3 billion years.

Then something mysteriously triggered a massive explosion of carbon dioxide on the planet 700 million and 750 million years ago, an event that Way thinks may be related to the volcanic activity of the planet.

"Something happened on Venus, where a huge amount of gas was released into the atmosphere and could not be swallowed up again by the rocks," added Way. On Earth, we have some examples of large-scale outbreaks, such as the creation of the Siberian traps 500 million years ago, which is associated with mass extinction, but nothing on this scale. It completely transforms Venus. "

Venus is closer to the Sun and its extreme surface temperature makes the existence of liquid water on the planet a dispute. But during the simulations, the researchers added an ocean of 310 meters deep, 1 deep 10 meters (32 feet), as well as placing some water in the soil.

There was also a scenario where they used the Topography of the Earth and the deep ocean at 1017 feet, as well as a planet "completely covered" by the ocean at 158 ​​meters deep and found that although Venus was closer to the Sun, than Earth, liquid water could be present.

WATER OUTSIDE THE POTENTIAL EXPANSION OF "HUMANITY", FIRST TIME, TEACHERS SAY

"At present, Venus has almost twice the amount of sunshine we have on Earth, Way we have. "However, in all scenarios. We modeled and found that Venus can still maintain surface temperatures subject to liquid water. ”

Whether it was volcanic activity on the planet or something, Venus is too hot to hold liquid water. Way said more research is needed to understand the history of the planet and how it may affect the demand for exoplanets, including those that can hold liquid water.

"We need more missions to study Venus and understand its history and evolution in more detail," said Wei. "However, our models show that there is a real possibility that Venus was habitable and radically different from the Venus we see today. This opens up all kinds of consequences for exoplanets found in the" Venus zone ", which may actually host the liquid water and temperate climates. "

Earlier this month, scientists discovered water vapor in the extrasolar atmosphere of a" super Earth "with potentially habitable temperatures, K2-18b, 110 light-years from Earth. [19659007] Click here to get the application of FOX NEWS
