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

The Technical Office for the Protection of the Quality of the Sky (OTPC) of the IAC is collaborating to advise about the implementation of energy efficiency and the reduction of light pollution in the port installations of general interest which belong to the public company Puertos Canarios. Specifically, the IAC has just issued a report which checks out the exterior lighting of the installations of the Port of las Nieves in Agaete (Gran Canaria), and in the coming months expects to carry out suitable tests in the Port of Vueltas in Valle Gran Rey (La Gomera) and the Port of Garachico

Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter present in the early universe into the sprawling strands of galaxies we see today. A new study using data from the Dark Energy Spectroscopic Instrument (DESI) has traced how this cosmic structure grew over the past 11 billion years, providing the most precise test to date of gravity at very large scales. DESI is an international collaboration of more than 900 researchers, included the Instituto de Astrofísica de Canarias (IAC), from over 70 institutions around the world and is managed by
