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

A delegation from the Instituto de Astrofísica de Canarias (IAC), led by its Director, Valentín Martínez Pillet, is attending the Big Science Industry Forum Spain 2025 (BSIFS2025), the main national meeting dedicated to the Big Science Industry, on 3 and 4 December. The team is presenting the centre’s scientific and technological advances and strengthening strategic links with companies, technology centres and international scientific infrastructures. The IAC strengthens its presence at Spain’s largest Big Science Industry forum The Big Science Industry Forum Spain 2025, organised by CDTI
