The Instituto de Astrofísica de Canarias (IAC) announces the arrival of the Astronomy on Tapinternational talk series in Spain, with its very first edition to be held in Tenerife. This outreach initiative, which was created in the United States and has since expanded worldwide, will now take place in the Canary Islands under the name "Astronomy on Tap – Canary Islands” and the local nickname “AstroTragos,” and is carried out within the framework of the EDUCADO and ExGal-Twin projects at IAC. The debut event will be held at the Búho Club (Calle Catedral, 3, La Laguna, Tenerife) on Thursday

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
