After months of work, the Canary Islands Institute of Astrophysics (IAC) successfully concluded its scientific, outreach, and educational program in Palencia, where thousands of people enjoyed the total solar eclipse on August 12, 2026. The program, designed jointly by the IAC and the Palencia City Council, filled the streets and theaters throughout the province. This historic event concluded with a high turnout. Thousands of people—including locals and visitors from all over the world—packed the viewing areas set up in Palencia to enjoy a once-in-a-lifetime astronomical spectacle live. The

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

An international team of scientists, including researchers from the Canary Islands Institute of Astrophysics (IAC), has confirmed the existence of three bodies orbiting the dynamic exoplanetary system TOI-201. They include a super-earth (TOI-201 d), a warm Jupiter (TOI-201 b) and a brown dwarf (TOI-201 c). The paper is published in Science Advances. “The goal was to characterize the TOI-201 planetary system to understand not just what planets are there, but how they interact with each other dynamically,” said Ismael Mireles, a PhD candidate in the UNM Department of Physics and Astronomy and
