An international team of astronomers, including researchers from the IAC, have performed a unique cosmic test - measuring the mass of an ancient star using two entirely different methods, finding agreement to within just 1.4%. This result marks a milestone in our ability to determine the ages of old stars and use them as living fossils to study the Milky Way’s distant past. The team analysed the red giant in the binary system KIC 10001167 using two independent approaches: firstly, by measuring the brightness and radial velocity variations due to the orbital motion of the binary, and secondly

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 PLATO (PLAnetary Transits and Oscillations of Stars) space mission, led by the European Space Agency (ESA), has recently completed one of the most delicate phases of its development: the integration of its main components, the 26 scientific cameras and the service module that houses all the instrument's acquisition, processing, and control electronics. This stage, carried out at the facilities of the aerospace company OHB in Germany, marks a fundamental step toward the launch scheduled for December 2026 from French Guiana aboard an Ariane 6 rocket. “Almost eight years after ESA gave the

The director of the Instituto de Astrofísica de Canarias (IAC), Professor Valentín Martínez Pillet, has been appointed Corresponding Academician of the Royal Academy of Exact, Physical, and Natural Sciences of Spain . This recognition recognizes his career and contributions to the scientific field. This follows the recent appointment of Antxón Alberdi Odriozola, current director of the Institute of Astrophysics of Andalusia , who has also been elected Corresponding Academician of the same institution. With these new appointments, the presence of astronomers in the Royal Academy of Sciences

The Instituto de Astrofísica de Canarias (IAC) has successfully completed the integration of the scientific detector into the FRIDA (inFRared Imager and Dissector for Adaptive Optics) instrument, an integra-field camera and spectrograph designed to work with the adaptive optics system of the Gran Telescopio Canarias (GTC or Grantecan), the world's largest optical and infrared telescope, located at the Roque de los Muchachos Observatory in La Palma. The integration was carried out in the laboratories of the National Autonomous University of Mexico (UNAM) in Mexico City by a team from the IAC
