The Gran Telescopio Canarias(GTC), on the point of completing 10 years of scientific operation, is still the largest optical and infrared telescope in the world. This status will be maintained until at least 2025 when the new generation of very large telescopes will start operating. The astrophyisicist Romano Corradi, its director since 2016 and an expert in planetary nebulae, gave a review of the present and future of this “singular infrastructure” during the VI Conference on Science with the GTC, which was held in Valencia.
