Alien Life Could Exist on Worlds Overflowing with Water, New Research Suggests

Even in the water-covered alien world, new research shows that life can survive for a long time - previous research showed that it is unlikely

In past studies, we know that these so-called "water worlds" can harm life because they can not stabilize the climate of the earth through the circulation of minerals and gases. However, in a new study, there is an objection that it can last for quite a long time since the formation of the marine planet, but how long it depends on each planet

In the past two decades, scientists have discovered thousands of outer planets. Most of them are rocks in the "habitable area" of their parent's star - water may be present on the surface of the earth. However, the scientists are still uncertain about the situation in which all live can be lived. Because we know so far only the living world, that is the earth. [Ten external planets that may support life]

According to a statement from this new study on the Earth, we better understand how the average planet can maintain stability of millions to billions of years of stability to make life a foothold For scientists pay attention to our own climate. . Our planet warms by releasing greenhouse gases into the atmosphere through volcanoes and then dissolving these gases in minerals in the Earth 's crust.

Researchers said in a statement that a new study based on more than 1,000 extra solar-system planet simulations suggests that the water world may be easier to live if certain conditions are met. Specifically, these planets require a certain amount of carbon, which is the element on which Earth 's life depends. The extrasolar planets require large amounts of water in the early stages of their formation and can circulate carbon between the atmosphere and the ocean to stabilize the system.

In addition, the outer planetary crust does not allow these minerals and elements to melt into the ocean and drive carbon out of the atmosphere, but it must retain its original elements and minerals.

Edwin Kite, a geophysicist at the University of Chicago, said in a statement: "This will drive the idea that you need Earth clones, land and shallow planets."

Although they simulated the planet around the star like the sun, the study also made the red dwarf an optimist, another hot spot to find life. This is because in the simulation we assume that light from a fixed star is always constant. In theory, this is also a red dwarf.

The red dwarfs are darker than our own sun, but if the planets are close enough to the stars, they can theoretically satisfy the conditions that they can live with their water on their surface . However, these stars are also significantly different and may emit radiation that takes their lives to their planets.

Now, the recent discovery and recent attention to the world of water means that it is a game between the outer water world and Mars, which is looking for extraterrestrial life. So far, Mars gave us all the signs of the world where we could live earlier. So, this may imply that we may find life, completely independent origin and evolution at two or three places in the solar system. How cool is this? By the end of the 1960's, when Mars seemed to be the world of death, when we did not know anything about the satellites of the outer solar system in the early missions, we considered a crater that is considered merely a cold death I found. It is the world. I know that there was a big pessimism about the evidence of birth or death, whether we could find life somewhere in the solar system. Why do things change?

The idea of ​​extraterrestrial life is not a new concept. For thousands of years, scientists and dreamers have learned about the existence of extraordinary things. It is not possible to determine whether an extraterrestrial exists anywhere in what we call infinite vast space, but if it exists, exactly like the living organism on the planet, that earth Develop attributes based on the unique environment of. Do the same. With the activation of the Kepler Space Telescope, NASA discovered that extrasolar planets are rich and diverse, each with unique planetary properties. I will classify the attributes of these different planets into three general categories of family planets and potential species of stars in order to explore how life in the alien world looks like .
