A team of scientists working at the University of Warwick has recently revealed the first weather map, which belongs to a planet outside the solar system. The unique thing is the presence of winds on the exoplanet at a very fast speed.
Tom Louden, one of the scientists on the project, said that it was known that wind was present on exoplanets, but this is the first time that the speed has been measured, and a complete weather system has been mapped.
The weather map of the exoplanet shows that winds blow as fast as 5,400 miles per hour said a report on Pierce Pioneer.
The exoplanet in question has been named as HD 189733b and is around 63 light years away from Earth. The exoplanet is a part of what is known as the Vulpecula (Fox) constellation and resembles that of Jupiter.
Scientists also added that “resolution spectroscopy of the sodium absorption” in the atmosphere has been used to study the velocity.
Planet HD 189733b has a belt of the wind at the equator, which travels 5400mph per hour, from the heated day side to night. The planet is also known to be very hot.
Peter Wheatley, who is also a co-author of the study, said that the scientists are excited to find a new and unique way to measure and map weather systems of distant planets. With more development in the technique, it will be possible to study the wind in more detail and make weather maps of other plants, as well.
This also opens the possibility to create weather maps of planets that resemble Earth.
