The course, taught by Hannah Thiel, a researcher at the Vigo Quantum Communication Center, brought Institute staff together around the foundations, applications and technological challenges of quantum communications and quantum key distribution. The Instituto de Astrofísica de Canarias (IAC) held a specialised course on quantum communications on 28 and 29 July, organised at the invitation of the Free Space Optics Communications Lab of the CELESTE project. The training, delivered by researcher Hannah Thiel, from the Vigo Quantum Communication Center at the Universidad de Vigo, took place at

An international team of astronomers, including researchers from the Instituto de Astrofísica de Canarias (IAC) and the Gran Telescopio Canarias (GTC), has observed a dramatic change in a supermassive black hole. Located about 10 billion light-years away, the object dimmed to roughly one-twentieth of its former brightness in just two decades — an extraordinarily short interval on cosmic timescales. The discovery was made within a collaborative observing framework linking Japan’s Subaru Telescope with the GTC in Spain’s Canary Islands at the Roque de los Muchachos Observatory, in La Palma
