The European Southern Observatory (ESO) has signed an agreement with an international consortium of institutions, including the Instituto de Astrofísica de Canarias (IAC), the Instituto de Astrofísica de Andalucía (IAA) and the Centro de Astrobiología de Madrid (CSIC-INTA), for the design and construction of ANDES, the ArmazoNes high Dispersion Echelle Spectrograph. The instrument will be installed on ESO’s Extremely Large Telescope (ELT). It will be used to search for signs of life in exoplanets and look for the very first stars, as well as to test variations of the fundamental constants of

En 2025, el Instituto de Astrofísica de Canarias (IAC) celebra el cuarenta aniversario de su inauguración oficial en 1985, consolidándose como uno de los principales centros de investigación de Astrofísica a nivel internacional.

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
