Massive stars in metal-poor galaxies often have close partners, just like the massive stars in our metal-rich Milky Way. This has been discovered by an international scientific team in which research staff from the Instituto de Aastrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL) participate. They used the European Very Large Telescope in Chile to monitor the velocity of massive stars in the Small Magellanic Cloud. The research is published in Nature Astronomy . For the past twenty years, astronomers have known that many massive stars in the metal-rich Milky Way have a

The Instituto de Astrofísica de Canarias (IAC) is actively participating in the observation of object 3I/ATLAS (C/2025 N1 ATLAS), initially included as A11pl3Z in the confirmed list of Near-Earth Objects (NEOs) of the International Astronomical Union's Minor Planet Centre (IAU/MPC). The object, which has been shown to be the third interstellar object detected in our solar system, was discovered by one of the telescopes in the ATLAS network for the detection and early warning of asteroids on an Earth-impact trajectory. The IAC is part of this network with its new telescope structure, ATLAS

The European Space Agency’s Euclid mission released its first batch of survey data, including a preview of its deep fields. Using Artificial Intelligence (AI) algorithms in combination with citizen science campaigns, the Euclid Consortium scientific results include the discovery of strong gravitational lensing systems, the exploration of galaxy clusters and the cosmic web, the characterisation of active galactic nuclei (AGN) and quasars, studies on galaxy evolution and morphology, and the identification of numerous dwarf galaxies and transients. Spain has an important role in the Euclid
