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

A team of researchers from the Instituto de Astrofísica de Canarias (IAC), collaborating with other international institutions, has managed to find new galaxies in the Spiderweb protocluster. This was possible thanks to the James Webb Space Telescope, which is a project of the space agencies of the United States (NASA), Europe (ESA) and Canada (CSA). Exploring the populations of galaxies, and discovering their physical properties in large scale structures helps astronomers to understand galaxy formation and how their assembly is determined by their environment. The “ Spiderweb” protocluster

The IACTEC headquarters has recently hosted the meeting between the engineering team behind the future European Solar Telescope and an international panel composed of some of the world's leading experts in the development of large telescopes and solar observation instrumentation. It is common for major scientific projects to undergo this type of scrutiny during their development as a way to independently verify their quality and viability. The evaluation process began over a month ago with the submission of all the design documentation to the reviewers. In this case, the evaluation focused
