The Instituto de Astrofísica de Canarias (IAC) has successfully completed the integration of the scientific detector into the FRIDA (inFRared Imager and Dissector for Adaptive Optics) instrument, an integra-field camera and spectrograph designed to work with the adaptive optics system of the Gran Telescopio Canarias (GTC or Grantecan), the world's largest optical and infrared telescope, located at the Roque de los Muchachos Observatory in La Palma. The integration was carried out in the laboratories of the National Autonomous University of Mexico (UNAM) in Mexico City by a team from the IAC

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

The Instituto de Astrofísica de Canarias (IAC), through its Communication and Scientific Culture Unit (UC3) and in collaboration with the Museum of Science and the Cosmos (MCC), part of Tenerife Museums, publishes the astronomical events for the year 2026 in its traditional calendar. The year 2026 will be marked by a total solar eclipse on 12 August, which will not be visible from the Canary Islands, but will be 70 per cent partial. In addition, 2026 will see the arrival of new comets, meteor showers and other interesting astronomical events. The IAC's 2026 Calendar is illustrated with a
