Two new studies have been used to make the most detailed weather map for a planet outside the solar system, where typical daytime highs reach 1500 degrees Celsius and winds exceed the speed of sound.
The discovery of water vapour in the atmospheres of three exoplanets includes the most precise measurement of any chemical in a planet outside the solar system, and has major implications for planet formation and the search for water on Earth-like habitable exoplanets in future.
