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

Using observations made with the Gran Telescopio Canarias (GTC) a study led from the Instituto de Astrofísica de Canarias (IAC) and the Universidad Complutense de Madrid (UCM) has confirmed that the asteroid 2023 FW14, discovered last year, is accompanying the red planet in its journey around the Sun, ahead of Mars and in the same orbit. With this new member, the group of Trojans which accompany Mars has increased in number to 17. But it shows differences in its orbit and chemical composition which may indicate that it is a captured asteroid, of a primitive type. The results are published in

The Instituto de Astrofísica de Canarias (IAC) and the European Solar Telescope Fundación Canaria (EST-FC) have signed thos Friday October 4th the agreement to promote the construction of the European Solar Telescope (EST). This ambitious project aims to consolidate and expand the Canary Islands' position as a world leader in solar physics research. The agreement was ratified by the director of the IAC, Valentín Martínez Pillet, and the representive of EST-FC, Manuel Collados. The signing act was attended by other members involved in the project: Héctor Socas-Navarro, Alejandra Martín; and
