In the search for life outside our solar system an international team of researchers has gone a step forward: astronomers have discovered for the first Time, water vapor in the atmosphere of a distant planet, orbiting its star in the so-called habitable Zone.
The one on Wednesday in the journal “Nature Astronomy”, published study. The celestial body is, according to the experts of the “most promising candidate” for the search to out of earthly life.
“to find water in a possibly habitable world where it is not the earth, is incredibly exciting,” said the Co-author of the study, Angelos Tsiaras, from the University College in London. “It brings us closer to the answer to the fundamental question: Is earth unique?”
The discovery was accomplished by using the Hubble telescope, the researchers said. The Fund does not means, however, that there is actually life on the 110 light-years away, exoplanet K2-18b.
“We can’t conclude that liquid water is on the surface of the exoplanet, but I think that this is very possible,” stressed the co-author Giovanna Tinetti, who also conducts research at University College in London. In addition, Mr. sche on the planet a temperature that is of the earth is very similar.
The Exoplanet K2-18b was discovered in 2015 by the US space telescope Kepler. It orbits the sun K2-18, a red dwarf star in the constellation Leo, in the so-called habitable Zone – a distance from its parent sun, could allow the permanent existence of liquid water on its surface. K2-18b is likely to consist of silicates, like the earth, Mars and Venus, as well as ice cream.
Recently, an international team of researchers had discovered, with the participation of the University of Göttingen, three new planets, one of which may be habitable. In the constellation of the water snake (Hydra) discovered exoplanets orbiting the 31 light-years distant star GJ 357. He has a third the mass and Size of our sun, such as the University of Göttingen was at the end of July informed. (SDA)
