A team of astronomers led by ICE-CSIC analyzed for the first time a long radio-observation of a scallop-shell star in a pioneer study. The team observed the star using the Giant Metrewave Radio Telescope (GMRT) located in Pune (India), and related it to the photometric information from NASA’s Transiting Exoplanet Survey Satellite (TESS) and Las Cumbres Global Telescope Observatory. Scallop-shell stars are a recently discovered class of young M dwarfs. More than 70% of the stars in the Milky Way are M dwarfs, although there are only around 50 recently confirmed scallop-shell stars. They show

The Instituto de Astrofísica de Canarias (IAC) is one of the international researches centres which is following actively the asteroid 2024 YR4 which has been qualified by the United Nations (UN) as potentially dangerous, because it has a 1.5% probability of impacting the Earth during 2032.The asteroid was discovered in 2024 and has an estimated size of between 40 and 90 metres. Given these figures, the UN has activated the protocols of planetary defence to obtain more accurate estimates of the orbit, the size and the threat which might be presented by 2024 YR4. The protocols of the UN are

The Instituto de Astrofísica de Canarias (IAC) has opened the application period for the XXXVI Canary Islands Winter School of Astrophysics , which will be held from 17 to 22 November 2025. This edition is carried out in the framework of the CELESTE (Centre for Optical and Space Technologies of the IAC) programme funded by the European Union and will focus on key optical technologies for astronomy, a field that is driving 21st century discoveries about the universe. Applications will be accepted until Friday, 13 June. The IAC’s Winter School is renowned for its educational approach and
