An international scientific team, involving the University of La Laguna (ULL) and the Instituto de Astrofísica de Canarias (IAC), has identified the cause of an unusually long dimming of a distant star . The phenomenon is explained by the passage of a substellar object with a giant ring system, similar to a ‘cosmic saucer’, in front of the host star. The star, named ASASSN-24fw, is located in the Monoceros constellation at about 3,000 light-years away from Earth. The star faded steadily for more than nine months between late 2024 and mid-2025 to about 97% dark before returning to its normal
El Instituto de Astrofísica de Canarias (IAC) se ha acreditado como Centro de Excelencia Severo Ochoa, según la resolución provisional publicada por la Agencia Estatal de Investigación (AEI), dependiente del Ministerio de Ciencia, Innovación y Universidades (MICIU). Este reconocimiento distingue a los centros de investigación españoles con mayor impacto y liderazgo científico internacional. Con esta nueva concesión, el IAC se consolida entre las instituciones científicas de referencia en España, siendo uno de los pocos centros que ha obtenido este sello de excelencia en cuatro ocasiones.

A team of scientists, including astrophysicist Carlos Hernández Monteagudo from the University of La Laguna (ULL) and the Canary Islands Institute of Astrophysics (IAC), has compiled one of the most comprehensive catalogues of small bodies in the Solar System, based on photometric observations made from Earth. The study, published in Monthly Notices of the Royal Astronomical Society, compiles data on 6,579 asteroids, comets and irregular satellites, mainly from the main belt located between Mars and Jupiter, opening up new possibilities for studying their composition and rotation. The
