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 Canary Islands Institute of Astrophysics (IAC) is promoting knowledge about European project management with a dedicated forum taking place on April 23 and 24 at the IACTEC headquarters in Tenerife. The 2025 ExGal-Twin Regional Workshop on European Project Management is an event organized by the ExGal-Twin project and the Office of Transfer and Institutional Actions (OTAI) of the Instituto de Astrofísica de Canarias (IAC), under the title "Innovation in European Project Management: Challenges and Opportunities" . The main objective of this workshop is to bring together R&D&I entities

The single star nearest to the Sun is called Barnard’s star. A team of researchers led by the Instituto de Astrofísica de Canarias (IAC), has recently detected a ‘sub-Earth’ orbiting it. This exoplanet, called Barnard b has at least half the mass of Venus and orbits rapidly around its star, so that its year lasts only a little over three Earth days. This new exoplanet is sixteen times nearer to Barnard’d star than Mercury is to the Sun, and has a surface temperature close to 125oC, so it does not have liquid water on its surface. This discovery, led by the IAC in collaboration with a number
