One of the most extreme planets known is more complex than previously thought. Researchers from the University of Bern, the University of Geneva and the National Research Capability Center (NCCR) analyzed the atmosphere. exoplanet WASP-189b and found that it can be layered just like Earth. The study was published in nature astronomy (And you can read it in full at this link) This Thursday (27/1).

In the case of Earth, the planet has five layers, each with a function, such as the troposphere, where most weather events occur, and the stratosphere, which contains the ozone layer that protects us from harmful ultraviolet radiation from the Sun. ,

In the case of WASP-189b, the researchers detected the presence of titanium oxide, which may play a role similar to the ozone layer on Earth. In addition, the scientists found that the presence of other gases in the planet’s atmosphere differed with respect to what the researchers expected, which may indicate to them that each gas is in different layers. These results could change the way astronomers investigate exoplanets.

WASP-189b is outside the Solar System and is located at a distance of 322 light years from Earth. It is a planet similar to Jupiter. In the analysis, the scientists found that the planet is 20 times closer to its host star than Earth and has a day temperature of 3200 °C.

Exoplanets are planets that are outside the solar system. it is already known Existence of more than 4 thousand planets of type.
