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.

On January 7, 2025, the European Commission established the Cherenkov Telescope Array Observatory (CTAO) as a European Research Infrastructure Consortium (ERIC), furthering its mission to become the world’s largest and most powerful observatory for gamma-ray astronomy. The creation of the CTAO ERIC will enable the Observatory's construction to advance rapidly and provide a framework for distributing its data worldwide, significantly accelerating its progress toward scientific discovery. “The ERIC will streamline the construction and operation of the Observatory in a way that will undoubtedly

The international CTAO LST Collaboration , in which the Instituto de Astrofísica de Canarias (IAC) plays a prominent role, released remarkable findings from observations of GRB 221009A—the brightest gamma-ray burst (GRB) ever recorded. The results were published by the renowned journal The Astrophysical Journal Letters (ApJ Letters) . The publication presents in-depth observations conducted in 2022 with the Large-Sized Telescope (LST ) prototype, the LST-1, during its commissioning phase at the Roque de los Muchachos Observatory (ORM) on the CTAO-North site in La Palma, Spain.
