The four large sized telescopes of the CTAO on La Palma reach a key milestone in their construction The LST-2 telescope has successfully completed the installation of its camera support structure (CSS), making it the last of the four Large Sized Telescopes ( LST ) to reach this important milestone in its construction at the Roque de los Muchachos Observatory of the Instituto de Astrofísica de Canarias (IAC) on La Palma. This telescope is part of the ambitious CTAO ( Cherenkov Telescope Array Observatory ) project, which will create the world's largest network of telescopes for the detection

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) is actively participating in the observation of object 3I/ATLAS (C/2025 N1 ATLAS), initially included as A11pl3Z in the confirmed list of Near-Earth Objects (NEOs) of the International Astronomical Union's Minor Planet Centre (IAU/MPC). The object, which has been shown to be the third interstellar object detected in our solar system, was discovered by one of the telescopes in the ATLAS network for the detection and early warning of asteroids on an Earth-impact trajectory. The IAC is part of this network with its new telescope structure, ATLAS
