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

As part of Open Government Week, which is being held from 19 to 25 May, the Instituto de Astrofísica de Canarias (IAC) has organised open days at its facilities in La Laguna (Tenerife) to bring its research and technological activity closer to the public. This international initiative aims to promote the values of transparency, citizen participation and accountability in public administrations. The visits, in which dozens of people took part in different shifts, were held on Monday 19 May at the IAC headquarters and on Tuesday 20 May at the IACTEC building, the Institute's technological and

Next Friday, May 23, at 17:30, the Museum of Science and the Cosmos of Tenerife will host the popular science lecture "The James Webb Telescope: Highlights and Life Beyond Earth," delivered by the renowned British astronomer Martin Ward, Emeritus Temple Chevallier Professor of Astronomy at the University of Durham (UK) and Fellow of the Royal Astronomical Society . This event, organised as part of the European ExGal-Twin Project , will offer the public a unique opportunity to learn about the most significant advances made by the James Webb Space Telescope, the largest and most powerful
