The Instituto de Astrofísica de Canarias (IAC) and Wikimedia Spain are organising, on the occasion of the International Day of Women and Girls in Science, a Wikipedia editing workshop and an edit-a-thon of biographies of female astronomers and astrophysicists, an initiative that seeks to highlight the talent of women in the field of astronomy and astrophysics and contribute to reducing existing content gaps in the free encyclopaedia. The proposal is divided into two complementary days, designed to facilitate participation by anyone, regardless of their level of prior knowledge about editing

The Canary Islands Institute of Astrophysics (IAC) is organising the 37th Canary Islands Winter School of Astrophysics, which will take place in San Cristóbal de La Laguna (Tenerife) from 16 to 27 November 2026. This edition will focus on the study of massive stars as tools for understanding processes ranging from star formation to gravitational wave events and core-collapse supernovae. The training programme is aimed at around 75 students on advanced master’s and doctoral programmes, as well as postdoctoral researchers in the early stages of their careers. Over the course of two weeks

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
