As part of Open Government Week, which is being held from 19 to 25 May, the Instituto de Astrofísica de Canarias (IAC) has organised open days at its facilities in La Laguna (Tenerife) to bring its research and technological activity closer to the public. This international initiative aims to promote the values of transparency, citizen participation and accountability in public administrations. The visits, in which dozens of people took part in different shifts, were held on Monday 19 May at the IAC headquarters and on Tuesday 20 May at the IACTEC building, the Institute's technological and

The Instituto de Astrofísica de Canarias (IAC) organised the international conference From Fake News to Real Clusters: The Controversial Fate of High-z Galaxy Protoclusters, which was held at the IACTEC building of the Las Mantecas Technology Park in La Laguna (Tenerife, Spain) from 13 to 16 May 2025. This meeting brought together around 30 researchers dedicated to the study of protoclusters and large-scale structures in the early stages of the universe. The event focused on the latest findings from multi-frequency observations and advanced modelling techniques, with a special focus on

An observationally based study, led by Martín López Corredoira, researcher at the Instituto de Astrofísica de Canarias (IAC) has found that certain very distant massive galaxies appear to be older than the limit set by standard cosmology. The study, published in The Astrophysical Journal, is based on the analysis of data recently obtained by the James Webb Space Telescope of galaxies that existed when the universe was only between 4% and 5% of its present age, according to the accepted standard model of cosmology. The researchers infer that the mean age of some of these galaxies would not be
