The Roque de los Muchachos Observatory (ORM) of the Instituto de Astrofísica de Canarias (IAC), located on La Palma, has reached another important milestone with the installation of the camera of the LST-4, one of the four Large-Sized Telescopes (LST), which will be part of the Cherenkov Telescope Array Observatory (CTAO), currently under construction. The installation of the camera represents the completion of the telescope assembly and marks its transition to the commissioning phase. After a thorough performance evaluation at the IACTEC building, the IAC's technological and business

The Canary Islands Institute of Astrophysics (IAC) is organizing the XXXVI Canary Islands Winter School of Astrophysics , which will be held in San Cristóbal de La Laguna (Tenerife) from November 17 to 22, 2025. Under the title "Key Optical technologies for Astronomy", the school will focus on cutting-edge optical and algorithmic technologies that will define the future of Astrophysics. This edition, led by Professors Jeff Kuhn (University of Hawaii and IAC) and Rafael Rebolo (IAC), will involve approximately 35 advanced Master's students, doctoral candidates, and early-career postdoctoral

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
