Using observations made with the James Webb Space Telescope (JWST), an international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, has confirmed variations in morning and evening atmosphere of the exoplanet WASP-39 b, about 700 light-years away from Earth. The research has revealed differences in temperature and atmospheric pressure, as well as indications of different cloudiness and winds that could reach thousands of miles per hour. The results are published in Nature. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but

Research led by the Instituto de Astrofísica de Canarias (IAC) has used an innovative technique based on artificial intelligence to study how stars form in galaxies. By analysing 10 000 nearby galaxies, the team have discovered that most stars are born within their own galaxy. Galactic mergers, while important, are not the main source of new stars. Furthermore, the study reveals that more massive galaxies are more affected by these mergers. These results, published in Nature Astronomy, provide new clues about the complex history of galaxies and their evolution over time. Most galaxies do not
