The most detailed exoplanet weather map ever

Published on 01/10/2014 
In this artist illustration the Jupiter sized planet WASP-43b orbits its parent star in what is one of the closest orbits ever measured for an exoplanet of its size — with a year lasting just 19 hours. The planet is tidally locked meaning it keeps one hemisphere facing the star, just as our Moon keeps one face toward Earth. The colour gradient on the planet represents the temperature across its atmosphere. This is based on data from a recent study that mapped the temperature of WASP-43b in more detail than has been done for any other exoplanet. Credit ESA, NASA.

This is an artist's concept of the silhouette of the extrasolar planet HAT-P-11b as it passes its parent star. The planet was observed as it crossed in front of its star in order to learn more about its atmosphere. Credit: NASA/JPL-Caltech

Highest-precision measurement of water in planet outside the solar system

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.
