The TRAPPIST-1 system is a likely Earth-like ocean world

At least one of seven rocky planet NASA-1 star orbits could be a world of earth like earth, for example scientists who have created updated climate models in exoplanet. Researchers at the University of Washington from the United States said that it was a bright and bright star and that all seven stars of a star could be like Venus. Any early ocean would evaporate the planets, leaving them dense and lively.

"We are modeling unknown environments, not just the things that we see in the solar system will be around a star," said Andrew Lincowski, PhD student at Washington University. "We have done this research to show the appearance of different kinds of atmosphere," said Lincowski, author of the study published in the astrophysics magazine.

TRAPPIST-1, with 39 light years of age, is about nine percent of Sun's mass and about 12% its radius. A pretty cool "M nanoa" star – the most common type of universe – has a radius slightly longer than the planet Jupiter, but the mass is much larger. The seven groups of the TRAPPIST-1 planet have the Earth's size, and the third of them – the planet labeled e, f and g – is considered to be an inhabitable space around a star around a star, where a rocky planet may have liquid water. on its surface, thus giving it a life choice.

TRAPPIST-1 d walks the inner edge of the residential area, farther, TRAPPIST-1 hours in orbit before the outer edge of that zone. "This is a complete planet sequence that gives us information about the planetary sequence, especially when it's about a star that is very different from ours, the light differs," said Lincowski.

The radiation and chemistry models make space or wavelengths for each possible atmospheric gas, and the observers allow prediction of gas emissions in exoplanet atmospheres. Researchers have discovered that the detection of gas detected by Webb's telescopes at any time or other times, "will be used by astronomers to hit gasps and wiggles in the spectrum, and such things would be enough to say something like the planet's composition, the environment, and perhaps the history of its evolution." Due to the habitability of a planet in the star of the sun, people think.

"But M nanoa stars are very different, you have to think about the chemical effects of the atmosphere and this chemistry affects the climate," said Lincowski. TRAPPIST-1 b, the closest to the star, is hot, as the clouds of sulfuric acid, like Venus.

The planet will receive more energy from the star than Venus and Earth's sun, c and d in Venus and the sun could be the sun and Venus in a dense and inanimate atmosphere. TRAPPIST-1 e is the probability of leaving seven liquid water at a temperature above ground, and it would be an excellent option to consider more habits.
The outer planets could be similar to Venus, f, g and h, or could be frozen, depending on the water that is produced during its evolution. Lincowski said that today, any planet or all of TRAPPIST-1 could be like Venus, burned with water or oceans. On the surface of a planet when the vapor is evaporated, the star extends from ultraviolet light to the water molecules and releases hydrogen, which is the slightest element and can escape the gravity of a planet.

This can leave a lot of oxygen to get in the atmosphere and get rid of gritty water. It could be such a thick oxygen on the planet, but it's not a life-long one, and nothing has been seen yet.
