The Swiss National Centre of Competence in Research PlanetS (short: NCCR PlanetS) initiative is an interdisciplinary research programme dedicated to exoplanet research. It was established in 2014 by the Swiss National Science Foundation in June 2014, to combine research efforts into characterizing exoplanets from different institutions.
On their website’s outreach section Universe@Home, they have collected a number of multimedia projects, information repositories, teaching materials and other outreach pages. This is available in English, German and French.
