An international team, led by researchers from the Instituto de Astrofísica de Canarias (IAC) through the UNDARK project (Unravelling the Dark Universe from the Canary Islands Observatories), funded by the European Union through the Widening Participation and Spreading Excellence programme, has developed a new method to extract information from galaxy maps tracing the large-scale structure of the Universe and to better understand the physics governing the earliest moments of the Universe after the Big Bang. The study is published in the journal "Astronomy & Astrophysics" . The current best

The Instituto de Astrofísica de Canarias (IAC) and Wikimedia Spain are organising, on the occasion of the International Day of Women and Girls in Science, a Wikipedia editing workshop and an edit-a-thon of biographies of female astronomers and astrophysicists, an initiative that seeks to highlight the talent of women in the field of astronomy and astrophysics and contribute to reducing existing content gaps in the free encyclopaedia. The proposal is divided into two complementary days, designed to facilitate participation by anyone, regardless of their level of prior knowledge about editing

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
