On Jupiter, aurorae are linked to different phenomena, some of which have not yet been explained. Combined observations by means of the Hisaki and Hubble satellites have made it possible to identify one of these previously poorly understood mechanisms.

Astronomers from the Universities of Cambridge and Liège have measured significant changes in the temperature of a super-Earth, the famous 55 Cancri e, potentially induced by intense volcanic activity.

Planetologists observe a transpolar arc in Saturn’s auroral footprints for the first time. A rare phenomenon, considering the planet’s characteristics, and one whose existence no-one had suspected.

TRAPPIST, a ULg telescope based in Chile, played a part in the discovery of rings around the asteroid Chariklo. Up to now, such structures were only seen around giant planets.

The study of telluric exoplanets is still in its infancy, but rapid progress is being made thanks to two ambitious programmes in which researchers from ULg are participating.
