Mapping a super-Earth

Exoplanetology never ceases to surprise and is constantly progressing. Recently, a team of researchers from several institutes, including the University of Liege, established a longitudinal thermal brightness map of 55 Cancri e, a “super-Earth”, which is approximately forty light-years away from Earth. The challenge was to measure the evolution of the brightness of the planet [...]
