Thanks to images obtained by the James Webb Telescope (JWST), an international scientific team in which the Instituto de Astrofísica de Canarias (IAC) participates has been able to verify that galaxies in the early universe are usually flat and elongated, and not round or spiral like the nearest galaxies. International research has found, by analysing high-resolution, infrared images of the JWST, that flattened oval disc and tube-shaped galaxies were much more common when the universe was between 600 million and 6 billion years old. In contrast, the nearest galaxies have clearly defined

An international collaboration, with participation by the Instituto de Astrofísica de Canarias (IAC), has found a system of six exoplanets orbiting a central star with a precise rhythm.This phenomenon, known as orbital resonance, is common during the starting phase of planet formation, but it is exceptional to find a system with such a large set of planets which conserves this kind of gravitational synchronism. This finding shows that the system has not undergone major changes during its six billion year history, so that it gives an unusual view of the formation and evolution of planets. The

Researchers at the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), publish today in the journal Astronomy & Astrophysics the first results of a detailed study of nearly a thousand blue supergiants in the Milky Way. This is the biggest sample of stars of this type which has been studied until now. The study has used over 15 years of high quality observations taken mainly with the NOT and Mercator telescopes at the Roque de los Muchachos Observatory in La Palma. The analysis of these data will allow researchers to improve their knowledge of the evolution of
