The nights in the German federal states („Bundesländer") have been getting brighter and brighter in the last four years -- but not everywhere at the same rate and with one exemption: Thuringia. This is the result of a study by scientists Chris Kyba and Theres Küster from the GFZ German Research Centre for Geosciences together with Helga Kuechly from 'Luftbild - Umwelt - Planung, Potsdam'. They published the study in the International Journal of Sustainable Lighting.
