Life could exist on the vast number of "water worlds" in our solar system, researchers have concluded. However, a new study from the University of Chicago and the Pennsylvania State University's ocean planets in the "Sweet" increased the likelihood that life has evolved on other planets, "according to another recent study that shows that one of three planets outside the solar system that are larger than the Earth is a water world, reports Daily Mail
"This really contradicts the idea that you need a clone ̵
Co-author Eric Ford of Kite and Penn State created a simulation of thousands of randomly generated planets and tracked their climate evolution over billions of years.  "The surprise was that many of them st stable for more than a billion years, just by the luck k the draw, "said Kite.
"Our best estimate is that it is on the order of 10 percent of them."
These happy planets are in the right wing Englisch: www.mps.mpg.de/en/topics/topic_200603.html They happened to have the right amount of carbon, and they do not have too many minerals and elements from the crust that is dissolved in the oceans, which would pull them carbon from the atmosphere.
They have enough water right from the beginning and only carbon between the atmosphere and the ocean, which in the right concentrations is enough to keep things stable.
"How much time does a planet have?" Is essentially dependent on carbon dioxide and how it was divided between the ocean, the atmosphere, and the rocks in its early years, "said Kite.
"There seems to be a way to see a planet inhabiting the Earth long-term without inhabiting the geochemical cycle."
The simulations took on tars that are like our own, but the results are also true for red dwarf stars Optimistic, kite said.
Planets in red-dwarf systems are considered to be promising candidates for life, as these stars are brightened much more slowly than our sun-giving lives.
The same conditions were modeled In this article, one could apply to planets around the Red Dwarfs: theoretically, one would only need the steady light of a star.
The study is an important impulse for the hunt for life.
One out of three planets outside the Solar System, larger than the Earth, is, according to recent research, a water world.
Scientists say that every "exoplanet" two to four times the size of Earth is likely to contain the main components of life (19659002) Analysis of data from the Kepler Cantonal Space Telescope and the Gaia mission indicates that Half of their weight can be water – either fluent or frozen.
By comparison, the amount of water on earth makes jus
Li Zeng from Harvard University in the US said, "It was a big surprise that there were so many water worlds."
So far, the 4,000 confirmed or eligible exoplanets are divided into two size classes.
They either have a planetary radius about 1.5 or 2.5 times that of Earth.
Now a group of international scientists has a
This is based on their recent mass and radius measurements of the Gaia satellite.
Dr. Zeng said, "We investigated how mass refers to the radius, and developed a model that describes the relationship."
The model suggests that the smaller planets tend to be rocky planets – typically five times as massive like the earth.
The larger ones have about 10 times more mass – and are "probably water worlds," Dr. Zeng
Fin Presentation At the Goldschmidt conference in Boston, he said, "This is water, but not as it is here on Earth."
"Its surface temperature is expected to be in the range of 200 to 500 degrees Celsius lie.
"This surface may be wrapped in a water-vapor-dominated atmosphere, with a liquid layer of water underneath.
" As you go deeper, you expect that water to turn into high-pressure ice before we reach the solid rocky core.  "The beauty of the model is that it explains how the composition relates to the known facts about these planets."
