The Roque de los Muchachos Observatory (ORM) of the Instituto de Astrofísica de Canarias (IAC), located on La Palma, has reached another important milestone with the installation of the camera of the LST-4, one of the four Large-Sized Telescopes (LST), which will be part of the Cherenkov Telescope Array Observatory (CTAO), currently under construction. The installation of the camera represents the completion of the telescope assembly and marks its transition to the commissioning phase. After a thorough performance evaluation at the IACTEC building, the IAC's technological and business

An international team of astronomers, including researchers from the Instituto de Astrofísica de Canarias (IAC), the University of Liège and collaborators in UK, Chile, the USA, and Europe, has discovered a transiting giant planet orbiting the smallest known star to host such a companion — a finding that defies current theories of planet formation. The host star, TOI-6894 , is a red dwarf with only 20% the mass of the Sun , typical of the most common stars in our galaxy. Until now, such low-mass stars were not thought capable of forming or retaining giant planets. But as published today in

An international team, in which the Instituto de Astrofísica de Canarias participates, has succeeded in mapping for the first time the three-dimensional structure of the atmosphere of an exoplanet, that is a planet beyond the Solar System. This research, published today in Nature , has been able to discover very strong winds that carry chemical elements such as iron and titanium, which create certain weather patterns through the planet's atmosphere. This mapping opens the door to more comprehensive and detailed studies of the chemical composition and climate of other planets. Enric Pallé
