From Thursday, May 8th, to Friday, May 9th, the Canary Islands Institute of Astrophysics (IAC) is hosting the meeting of the Research Advisory Committee (CAI). This is the center's highest advisory body on research and analyzes its scientific and technological output. At this meeting, the director, Valentín Martínez Pillet, will present the center's main scientific and technological milestones, as well as a proposal for future lines of action. The director will also be joined by Eva Villaver, deputy director of the IAC; Romano Corradi, director of Gran Telescopio Canarias; Jonay González

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) has opened the application period for the XXXVI Canary Islands Winter School of Astrophysics , which will be held from 17 to 22 November 2025. This edition is carried out in the framework of the CELESTE (Centre for Optical and Space Technologies of the IAC) programme funded by the European Union and will focus on key optical technologies for astronomy, a field that is driving 21st century discoveries about the universe. Applications will be accepted until Friday, 13 June. The IAC’s Winter School is renowned for its educational approach and
