Water Saturday & # 39; Super Earth & # 39; Found by Hubble Belloscope at K2-18b

Mobilizers that deal with the meaning of discovery.

We need to grow as our planet and half times larger, K2 18b has powerful gravity that will make it difficult to move. This red dew is closer to the star, smaller than our sun and why, which bathes on Earth in extremely high levels of radiation.

And from water to vapor, its environment often consists of hydrogen gas.

Whether it is the rocky surface beneath its atmosphere, the frozen ocean or a large ball of gas, it still remains unknown, as is the importance of finding water vapor.


It was learned that two separate teams of scientists published at the same time.

A paper by Fergus Sorris, an expert at Fergus College London, combines publicly available data through a modeling weapon by Bj برنrn Br .ck at the University of Montreal in Canada, Canada.

Its star and atmosphere are different to ours, "a situation like the Earth is not possible," Sierras told reporters. "The only question we are trying to ask here is, and to move forward, this is a habit."

On Tuesday, Benn's team published their analysis of K2-18b on the Arctic, which does not include an array of academic papers yet published in peer-reviewed journals.

Beninak and his colleagues also found water lakes in the skies of K2-18b.

But they were less enthusiastic about the potential of the world than Sears. The Montreal-based team's assessment suggests that hydrogen forms a thick, gaseous envelope in the atmosphere. This would create intense pressure on the Earth's surface – probably enough to push hydrogen into a liquid form.

"This is not exactly one of a single planet," the researchers report.

Laura Kreidberg, a stoner for the Harvard-Smithsonian Center of Aerophysics, said that KO 18-18b would be described as "mini-Neptune" rather than "super-Earth."

Comprehensive research suggests that computer models suggest that the mass of the Earth is 1.6 to 1.8 times larger than the rocks on the planets.

Although K2-18b is its main ingredient, the temperature would rise so high on the surface and on the "surface" that some complex molecules would remain, let alone life.

"I think the result is amazing," Krebsberg said. "Sure, it is the smallest and largest planet that has shined on us from a distance. But I think it is possible that this is possible."

Scientists have only discovered water in the atmosphere of the "gas giants", the smallest planes on the surface of massive planets, such as the Jupiter and Saturn in our solar system.

The smaller the rocks are, the more difficult they are to detect and more difficult to detect. Even a planet like Kloe 18-18 can only be tested with humanity's most sensitive stock telescopes.

When K2-18b was discovered, Sirius and his colleagues thought it would be a proposed candidate for analyzing transmission spectroscopy, which involves studying the changes in light of a star as a star, "transitions," Or passes before it.


The planet is close to its little host star, which only costs 33 days. So, month after month, the researcher waited with Hubble to grab the driver's trunk.

As the starlight is filtered through the atmosphere of the planet, it will absorb some of the planet's air gas. By separating the light into these parts, the scientists can find the signature of the particular molecules.

What they have found is that the atmosphere composition of KU18-18b can be up to 50% of 0.1% water vapor (with respect to the Earth's upper atmosphere). (On the contrary, water vapor in the Earth's low atmosphere is 4%)

The bubble is not sensitive to the right kind of light for detecting other molecules, such as nitrogen or methane, so the researchers can only speculate about the exact structure of the atmosphere.

The winter clouds, like Venus, can be warmed to an unprecedented degree. Or that the environment is so small and unnecessary that it might not be able to protect against space disturbances, such as the Mars environment.

Researchers have to wait for more sophisticated tools, such as the long-awaited James Webb Space Telescope, to reveal more details about their world.
