The first image of a new gaseous component in a planetary nebula.
False color image of the planetary nebula NGC 6778. In blue, the emission associated with weak lines of ion O++ recombination, taken with the OSIRIS tunable filter blue instrument in the GTC. In green, emission of the same ion in the excited lines by coll

IAC researcher David Aguado has obtained a prestigious Starting Grant from the European Research Council (ERC), aimed at promoting promising young scientists. This is the third ERC grant -one of the most competitive and recognized of the Horizon Europe program- that the center has received so far this year, thus consolidating its international projection. These highly competitive grants provide up to €1.5 million over five years to support outstanding young scientists in establishing their own independent research groups and pursuing pioneering scientific ideas. Searching for the first stars
From March 9–12, 2026, the Heidelberg Institute for Theoretical Studies – HITS hosted the Second Annual Meeting of the EDUCADO Doctoral Network (MSCA DN), a network coordinated and led by the Instituto de Astrofísica de Canarias. This pivotal gathering marks a significant milestone in the project’s timeline, bringing together international research groups from across the consortium. The meeting featured the 11 Doctoral Candidates as the central focus, providing them with a platform to present their research progress in applying AI to galaxy evolution and astronomical big data. A highlight of
The Universe is not distributed uniformly. Galaxies are arranged in a gigantic cosmic web made of voids, filaments, and galaxy clusters. These filaments act as enormous “cosmic highways” through which matter and galaxies flow toward the densest regions of the Universe. Understanding how these structures influence galaxy evolution is one of the major goals of modern astrophysics. In this work, we analyzed hundreds of thousands of galaxies from the Sloan Digital Sky Survey (SDSS) to study how galaxy density changes around cosmic filaments in the nearby Universe. Our main goal was to determine
