Such planets are known as stray or orphan planets. The brown dwarf “SIMP-0136” is about 20 light-years away from the sun, and occupies a mediator location between the star and the planet. Thanks to the high sensitivity to the telescope James WebScientists managed to monitor slight changes in the brightness of this circular heavenly body, which allowed them to study temperature fluctuations, chemical composition, and form clouds in its atmosphere.

The results revealed a strong compassionate activity similar to the polar twilight on the ground and giant lights on the buyer, which leads to additional heating of the upper layers of the atmosphere. The planet’s temperature exceeds 1500 ° C, while the fluctuations are associated with (5 degrees Celsius) to changes in chemical composition, indicating the presence of stormy regions that resemble the great red spot on the buyer.

It is interesting that the planet is covered with low clouds that do not disappear, but they are not water -origin, but rather consisting of silicate molecules – similar to sand grains – formed at very high temperatures.

Dr. Evert Nassedkin, a researcher at the Physics School at the Trinity College and the main author of the research published in Astronomy & AstrophySics:
“This is one of the most accurate measurements of the atmosphere of any celestial body outside the solar system at all, and it is the first time that changes in the properties of the atmosphere are directly measured.”
