The Instituto de Astrofísica de Canarias (IAC) has initiated a project of science outreach in the Tenerife-II prison in El Rosario, with the aim of bringing knowledge about the Universe to the prisoners, as well as to the educational and other working personnel at that centre. This initiative is taken in the framework of the commitment of the IAC to the popularization of science as a tool for inclusión and social transformation. The project is led by the astrophysicist, and IAC researcher David Aguado and is a continuation of a first experiment in 2024 in the Madrid V prison at Soto del Real

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), through its Communication and Scientific Culture Unit (UC3) and in collaboration with the Museum of Science and the Cosmos (MCC), part of Tenerife Museums, publishes the astronomical events for the year 2026 in its traditional calendar. The year 2026 will be marked by a total solar eclipse on 12 August, which will not be visible from the Canary Islands, but will be 70 per cent partial. In addition, 2026 will see the arrival of new comets, meteor showers and other interesting astronomical events. The IAC's 2026 Calendar is illustrated with a
