An article published in the journal “Nature” describes a research on the exoplanet WASP-96b. It’s a hot Saturn, meaning a gas giant with a Saturn-like mass and an orbit close to its star which has as a consequece a high temperature on its surface. A team of researchers led by Nikolay Nikolov of the British University of Exeter used the FORS2 spectrograph mounted on ESO’s VLT to study WASP-96b discovering strong traces of sodium, an observation possible only in the absence of clouds in its atmosphere.
