Last night, the 5,000 fibre-optic ‘eyes’ of the Dark Energy Spectroscopic Instrument (DESI) reached a major milestone, having fully covered the area originally planned for its map of the universe. Thus, DESI’s five-year programme has concluded ahead of schedule and with far more data than expected, resulting in the largest high-resolution 3D map of the universe ever produced. This map will enable researchers to explore dark energy, which accounts for 70% of the universe and drives its accelerated expansion. By comparing how galaxies were distributed in the past with their current

The Instituto de Astrofísica de Canarias (IAC) welcomed the visit of Professor Didier Queloz, Nobel Laureate in Physics and co-discoverer of the first exoplanet orbiting a Sun-like star. Professor Queloz's stay at the IAC has focused on instrumental development and technological collaboration. As part of his agenda, he also gave a lecture entitled ‘Exoplanets: the next frontier’ in the IAC Lecture Hall. The researcher visited the IAC to supervise the installation of a new high-stability spectrograph on the Isaac Newton Telescope (INT) at the Roque de los Muchachos Observatory on La Palma

The international consortium Sloan Digital Sky Survey-V (SDSS-V) has appointed Dr Sebastián Francisco Sánchez, researcher at the Institute of Astronomy of the National Autonomous University of Mexico and senior scientist on leave from the Instituto de Astrofísica de Canarias (IAC), as director of the Local Volume Mapper (LVM) project, one of the three surveys that make up the SDSS-V. This appointment recognises Dr Sánchez's academic excellence and consolidates the collaboration with the IAC, with which the researcher has maintained a close scientific relationship for many years. Dr Sánchez
