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

Astronomers at the Instituto de Astrofísica de Canarias (IAC), using the 2-meter robotic Two-meter Twin Telescope (TTT) at the Teide Observatory, have obtained the deepest optical images ever taken of Malin 2, one of the largest and faintest spiral galaxies in the Universe. These ultra-deep observations have revealed previously unseen structures, including several diffuse stellar emissions and a striking, elongated spiral-like feature, hinting at past interactions with other galaxies. The team has also identified a potential ultra-diffuse dwarf galaxy (UDG) about 400,000 light-years from

During October, the Adaptive Optics System team at the Gran Telescopio Canarias (GTCAO) of the Instituto de Astrofísica de Canarias (IAC), in collaboration with the technical team at the Gran Telescopio Canarias (GTC or Grantecan), successfully completed the integration of the GRANCAIN instrument into the world's largest optical-infrared telescope. The installation was carried out at the GTCAO outlet on the telescope's Nasmyth B platform, a key step in initiating performance testing of the new adaptive optics system. This is the first scientific instrument to operate using the GTC's adaptive
