The European Space Agency (ESA) has given the green light to build the flight models of the spacecraft and science payload for the PLATO mission to search for extrasolar planets.
In the "Solar and Stellar Interiors" department, Laurent Gizon, Jesper Schou, Aaron Birch, Robert Cameron and others offer PhD projects in solar physics and astrophysics. Helioseismology and asteroseismology are used as important tools to study the oscillating Sun and stars.
The longest-serving solar observatory in space has turned 25 and is still making significant contributions to solar research. Its old age has become an important merit.
