The Instituto de Astrofísica de Canarias (IAC) in collaboration with the University of Geneva (Switzerland), the University of Osaka (Japan), and the University of Zhejiang (China) has made a key contribution to a more precise measurement of the expansion of the Universe. This is because they have made an improvement in the precision of the calculation of the scale of the universe in its early stages using the analisis of the distribution of gas in intergalactic space, measurements which reach back to epochs between 10,000 and 12,000 million years ago. This result comes from the análisis of

The Instituto de Astrofísica de Canarias (IAC) is demonstrating the quality and international relevance of the Canary Islands Observatories at the 245th session of the American Astronomical Society (AAS) meeting being held this week in Maryland (USA). This meeting, led by the American astrophysics community, brings together the world's most important research centres in this field to share lines of work and proposals for the present and the future. The IAC delegation in Maryland is headed by the director of the centre, Valentín Martínez Pillet, who is part of the panel of speakers with a

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
