Moscow, Nov. 5 – AiF-Moscow. An international team of astrophysicists could see clouds caused by variations in the radiation rogue planet PSO J318.5-22. This is the first case in the history of observations of weather on the planet outside the solar system, Interfax reports, referring to Western media.
Open two years ago, the planet PSO J318.5-22 is a gas giant object that is from the Earth at a distance of 80 light-years away and is moving to the group of star Beta Pictoris, but does not have its own stars.
Watching a giant in the infrared, the scientists recorded the small brightness fluctuations, the cause of which, in their opinion, are the clouds.
On the basis of these data has been estimated the rotation period of the planet. It turned out that it makes one revolution for more than five hours.
According to astrophysicists, similar to the recorded vibrations can also be considered planets orbiting stars, albeit with some amendments. In this case, there is a chance to develop the technology of weather observations from real extrasolar planets.
These observations were made during a large-scale program for the study of brown dwarfs and planets orphans, to which the PSO J318.5-22.
