The Instituto de Astrofísica de Canarias (IAC) announces the death of its founding director, Professor Francisco Sánchez Martínez, whose determination led to the creation of one of Europe's leading research centres and two of the world's finest astrophysical observatories: the Teide Observatory in Tenerife and the Roque de los Muchachos Observatory in La Palma. He passed away today in Madrid, where he had been living for the last few years, at the age of 89. The director of the IAC, Valentín Martínez Pillet, emphasises that "Professor Sánchez's legacy is incalculable. He was a man who paved

An international scientific team, including members of the Instituto de Astrofísica de Canarias (IAC), has launched an ambitious program to map exoplanets located around the Neptunian Desert —a region around stars where planets the size of Neptune are very rare— in order to better understand the mechanisms of planetary system evolution and formation. This scientific expedition has delivered its first results with the observation of the TOI-421 planetary system. Analysis of this system reveals a surprisingly inclined orbital architecture, offering new insights into the chaotic history of

The Instituto de Astrofísica de Canarias (IAC) invites the public to visit the Teide Observatory (Izaña, Tenerife) during the weekend of 21 and 22 June, coinciding with the week of the summer solstice. The activity is part of its Open Days, a free science outreach initiative organised by the Observatory itself together with the IAC's Scientific Communication and Culture Unit (UC3). Over two days, those attending will be able to tour some of the most important scientific facilities at the centre, learn how they work from the technical and research staff, and make live solar observations.
