Water can be more important for foreign life than we think

The number of planets capable of hosting Alien Life can be less than we think, thanks to a new understanding of how the water level is flowing. At the bottom of a specified level, the carbon dioxide in the air can grow very much and make a planet that is not hot hot, which can also explain why Venus is now visible today.

All life we know is needed liquid water, why astronomers want to find the planets in the “home area” around their star with liquid. But now Haskelle White-Gielella At the University of Washington and his colleagues noticed that having some liquid water is not enough.

Researchers ran about 10,000 different simulations that calculates how to change the co₂ level depending on the amount of water above a wall of the land and receives an equal measure of light. They know that a planet requires at least 20 percent of the whole ground water for it that can be killed.

That’s because the water falls while the rain has a major role in storing carbon on the ground by prompting chemical reactions to rocks. Without enough rain, co₂ Build in the air on a planet, heat flow and rise to temperature more than 126 ° C (259 ° F) – beyond our knowledge, Even with the worst exampleslive.

“We know that there is a water threshold required to maintain a stable climate,” White-Giella told Goldschmidt Geoceming Conference in Prague, Czech Republic on 10 July.

This means that a planet is in a home area is not enough for this to be accommodated, as white-gella, and we should look closely at its geologic history.

An equal scenario can also explain how to scorn Venus, it’s an incredible environment that we can see today, as Whiteella at Conference. While sunshine since the birth of the solar system is considered primarily caused by vanity loss at Venus and increased temperatures, it is not fully explained these changes. White-Giellanla and his team also run their models to receive venus of star amounts, and know that even a planet with a lot of water₂ and homeless.

This is an inspirational explanation of how the planets like Venus are hotter, as Benjamin Tutolo At the University of Calgary, Canada, but the picture becomes more complicated when planets start less co₂ Over time, which we see in view of the Geologic record on Mars.

In the case of Mars, liquid water actually pulled a lot of carbon dioxide and stored this carbonate minerals on the ground, as tutolo, healing it. White-Giella says teammates focus on planets in soil sizes – like sizes, and agree that the situation can be different from Mars planets.
