    The Rubin Observatory begins its exploration of the sky with the support of the IAC and Grantecan
    The Vera C. Rubin Observatory, located in Chile, today released its first images of the universe, known in astronomy as an instrument's “first light”. This event marks the beginning of a project that will revolutionise our understanding of the universe over the next decade. Jointly funded by the US National Science Foundation (NSF) and the US Department of Energy (DOE), the Instituto de Astrofísica de Canarias (IAC) is participating, as part of a consortium of Spanish institutions, in its scientific exploitation and contributing observation time from the Gran Telescopio Canarias (GTC or

    The IAC is actively tracking the asteroid that the UN has qualified as potentially dangerous
    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

    James Webb infrared data reveal unexpected diversity in hidden quasars
    An international team led by Cristina Ramos Almeida, a researcher at the Instituto de Astrofísica de Canarias (IAC), has used the James Webb Space Telescope (JWST) to observe five dust-obscured quasars — and the results offer new insights into how galaxies and their central supermassive black holes may evolve. The study is published today in the journal Astronomy & Astrophysics . The energy released by supermassive black holes at the centres of galaxies is a fundamental ingredient in regulating the formation of new stars, and thus galaxy growth. This occurs during an active phase, usually
