The Instituto de Astrofísica de Canarias (IAC) announces the death of its founding director, Professor Francisco Sánchez Martínez, whose determination led to the creation of one of Europe's leading research centres and two of the world's finest astrophysical observatories: the Teide Observatory in Tenerife and the Roque de los Muchachos Observatory in La Palma. He passed away today in Madrid, where he had been living for the last few years, at the age of 89. The director of the IAC, Valentín Martínez Pillet, emphasises that "Professor Sánchez's legacy is incalculable. He was a man who paved

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
