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

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

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
