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 third telescope of the Two-metre Twin Telescope (TTT3) situated in the Teide Observatory of the Instituto de Astrofísica de Canarias (IAC) has seen its “first light”. This robotic 2 meter telescope, managed by the Canary company Light Bridges, is one of the largest of its kind in the world.

An international scientific team led by the Instituto de Astrofísica de Canarias (IAC) has identified a new super-Earth orbiting the star HD 176986, a K-type dwarf located about 91 light-years away. The finding, published in the journal Astronomy and Astrophysics, brings the number of known planets in this system to three and confirms the value of long-term observation campaigns for detecting small, wide-orbiting worlds. The observation campaign of HD 176986, an orange dwarf star or K-type star, slightly smaller than the Sun and located about 91 light-years away, has highlighted the

The Solar System research group at the Instituto de Astrofísica de Canarias (IAC) is participating in the international programme to keep a closet track of asteroid 2024 YR4. The aim is to determine its orbit with the highest possible precision before it stops being observable by ground based and satellite telescopes in April, and so improving our value of the probability that it will impact the Earth in 2032. In this context several telescopes of the Canary Observatories of the IAC are playing an outstanding role in this observing campaign: The Gran Telescopio Canarias (GTC) at the Roque de
