The project Czech European Researchers´ Night 2021 (SCIENCzEch 2021) supports the implementation of the European Researchers’ Night event in the Czech Republic. Czech Researchers' Night has been held in the Czech Republic since 2005 and is organised by Czech universities, scientific institutes, observatories and other institutions. The event is currently under the national coordination of VSB - Technical University of Ostrava and the University of Ostrava. In 2020, a prestigious European Marie Skłodowska-Curie Actions (MSCA) European Researchers' Night (NIGHT) grant was awarded, which put the Czech Researchers' Night on the European map. The Researchers' Night takes place on the last Friday of September, all over Europe. The specialty of the Czech organisers of the Researchers’ Night is a different central theme each year. This year's topic was TIME.
