A study conducted with the new WEAVE , installed on the Telescopio William Herschel (WHT) at the Observatorio del Roque de los Muchachos (La Palma), and in whose construction the Instituto de Astrofísica de Canarias (IAC) participated, has revealed clear signs of shock interaction in the Type II supernova SN 2023ixf. Almost a year after the explosion, the data obtained with WEAVE reveal complex emission features that provide new clues about the processes shaping the final stages of massive star evolution. SN 2023ixf, located in the nearby galaxy M101, is the closest Type II supernova

This Saturday, 29 March 2025, the Instituto de Astrofísica de Canarias (IAC) was able to follow the partial solar eclipse from the Teide Observatory in Tenerife. Although subtle to the naked eye, this eclipse was used by the IAC's outreach team to raise awareness of the phenomenon among a group of people from the ‘Friends of the IAC’ programme and IAC staff. At the same time, an observation was also made from the IAC Headquarters in La Laguna, which could be seen live on the centre's YouTube channel. The eclipse began at 09:14 UT and ended at 10:56 UT, with its maximum at 10:03 UT. For just

The Instituto de Astrofísica de Canarias (IAC) is joining the ninth edition of the PHE Festival , one of the most outstanding musical events of the summer in Tenerife. In this first collaboration, the IAC has organised a series of activities that bring astronomy closer to the general public, thus complementing the cultural offer of the festival. On 21 and 22 August, the IAC offered guided tours of the Teide Observatory, allowing visitors to get a first-hand look at one of the most important astronomical research centres in the world. These exclusive visits provided the opportunity to explore
