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) announces the arrival of the Astronomy on Tapinternational talk series in Spain, with its very first edition to be held in Tenerife. This outreach initiative, which was created in the United States and has since expanded worldwide, will now take place in the Canary Islands under the name "Astronomy on Tap – Canary Islands” and the local nickname “AstroTragos,” and is carried out within the framework of the EDUCADO and ExGal-Twin projects at IAC. The debut event will be held at the Búho Club (Calle Catedral, 3, La Laguna, Tenerife) on Thursday

From today until 5 December 2025, the Instituto de Astrofísica de Canarias (IAC) is hosting the SO/PHI Science and Team Meetings, an international gathering focused on the scientific and technical advances of the Polarimetric and Helioseismic Imager (PHI) instrument aboard ESA's Solar Orbiter (SO) space mission. The development of PHI was co-led by the Spanish Space Solar Physics Consortium (S3PC), which also currently coordinates its scientific operation and exploitation. The IAC is part of this network. PHI is a high-precision solar observation instrument equipped with two telescopes—one
