    An international team of researchers, including staff from the Instituto de Astrofísica de Canarias (IAC), has discovered a planetary nebula that destroyed its own planetary system, conserving the remaining fragments in the form of dust orbiting its central star. To date, more than 5000 exoplanets have been discovered orbiting stars of all kinds and almost every stage of stellar evolution. However, while exoplanets have been discovered around white dwarfs – the final stage in the evolution of low- and intermediate-mass stars like the Sun, no exoplanets have been detected in the previous

    On January 7, 2025, the European Commission established the Cherenkov Telescope Array Observatory (CTAO) as a European Research Infrastructure Consortium (ERIC), furthering its mission to become the world’s largest and most powerful observatory for gamma-ray astronomy. The creation of the CTAO ERIC will enable the Observatory's construction to advance rapidly and provide a framework for distributing its data worldwide, significantly accelerating its progress toward scientific discovery. “The ERIC will streamline the construction and operation of the Observatory in a way that will undoubtedly

    El Instituto de Astrofísica de Canarias (IAC) rinde homenaje a la historia de la Astrofísica en la isla de La Palma a través de su revista monográfica Paralajes que se distribuye tanto en su edición física como en digital. La revista se elaboró a lo largo del año 2024 bajo la coordinación de la periodista científica y exjefa de la Unidad de Comunicación y Cultura Científica (UC3) del Instituto de Astrofísica de Canarias (IAC), Carmen del Puerto, que ha recibido el apoyo del director de la revista Astronomía, Ángel Gómez Roldán: y de la actual jefa de la UC3, Verónica Martín. Además, ha

  • Momento de la reunión sobre protección de la pardela cenicienta / Cabildo de Tenerife
    El Instituto de Astrofísica de Canarias ha recibido el agradecimiento, de manos Pedro Millán, Director Insular de Medio Natural del Área de Medio Natural, Sostenibilidad, Seguridad y Emergencias del Cabildo de Tenerife, por su participación en la iniciativa “El Primer Viaje” para la protección de la pardela cenicienta. La iniciativa “El Primer Viaje” tiene el objetivo fundamental de aumentar el compromiso de los establecimientos de alojamiento turístico con la protección de las aves y en especial con la pardela cenicienta, así como informar al visitante de la situación ambiental de esta ave

    In the outer reaches of the Solar System, beyond the ice giant Neptune, are a series of objects called Centaurs, and transneptunian objects (TNO’s). The Instituto de Astrofísica de Canarias (IAC) is one of the most advanced international centers for the study of these objects, and co-leads one of the key studies which show what the coldest objects in the Solar Sytem are made of, and how thermal change is produced in their interiors. In two articles recently published in the same volumen of Nature Astronomy , spectra obtained with the James Webb Space Telescope (JWST) have shed new light on

  • light bridges
    Light bridges are elongated and bright structures protruding into the umbra of sunspots. The presence of light bridges has a significant role in the evolution of sunspots and the heating of their overlying atmosphere. Therefore, investigating these structures is crucial to understanding fundamental aspects of sunspots. By applying a novel code based on deep-learning algorithms called SICON to spectropolarimetric observations acquired with the Hinode satellite, we computed atmospheric parameters that allowed us to infer the variation of the physical properties of light bridges on a geometric
