The Instituto de Astrofísica de Canarias (IAC) welcomed the visit of Professor Didier Queloz, Nobel Laureate in Physics and co-discoverer of the first exoplanet orbiting a Sun-like star. Professor Queloz's stay at the IAC has focused on instrumental development and technological collaboration. As part of his agenda, he also gave a lecture entitled ‘Exoplanets: the next frontier’ in the IAC Lecture Hall. The researcher visited the IAC to supervise the installation of a new high-stability spectrograph on the Isaac Newton Telescope (INT) at the Roque de los Muchachos Observatory on La Palma

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
