  • Telescopio 'Breton Frères, Paris' utilizado en Palencia durante el histórico eclipse solar total de 1905 y restaurado en el IAC para su uso en el eclipse del 12 de agosto de 2026
    Press release
    Un telescopio histórico de 1905 vuelve a la vida un siglo después para observar el Sol en Palencia de la mano del IAC y el proyecto NATE
    Más de un siglo después de haber permanecido olvidado en el desván de un monasterio, un telescopio histórico del siglo XIX vuelve a apuntar hacia el firmamento para captar un eclipse total de Sol. El instrumento, un refractor del reputado fabricante Breton Frères, Paris que formó parte del equipamiento científico desplegado en Palencia durante el histórico eclipse solar total de 1905. Ahora, se realizado una restauración conservativa, recuperando su funcionamiento mecánico y óptico y respetando al máximo sus elementos para adaptarlo y estar listo para incorporarse a las observaciones

  • A comparison of dwarf galaxies
    Press release
    The IAC is leading a study which reveals that binary stars can mimic the effects of dark matter in smaller galaxies
    A team from the Instituto de Astrofísica de Canarias (IAC) has quantified for the first time the impact that the motions of binary stars can have on estimates of dark matter in some of the smallest galaxies in the universe. The study proposes a new methodology that will make it possible to obtain more precise measurements of the amount of dark matter present in these systems. The Milky Way, our galaxy, contains hundreds of billions of stars. However, dozens of much smaller galaxies orbit around it, dwarf companions that host thousands of times fewer stars and live embedded within our galaxy

    DALI supera el Preliminary Design Review y avanza en la búsqueda de materia oscura
    El experimento, desarrollado en el Instituto de Astrofísica de Canarias (IAC) e impulsado por un investigador del network del proyecto europeo UNDARK, recibe el respaldo de un comité internacional para construir un detector de nueva generación destinado a la búsqueda directa de materia oscura de alta frecuencia. El experimento DALI , liderado por Javier de Miguel, ha superado con éxito el Preliminary Design Review (PDR), una evaluación internacional que certifica la madurez científica y tecnológica del proyecto. Tras esta revisión, un comité independiente de expertos ha recomendado avanzar

  • A group of people with visual impairments experiencing a total solar eclipse
    Press release
    The August 12 event in Palencia is part of the “Inclusive Eclipse” initiative
    As part of the program of initiatives that the IAC—in collaboration with the Palencia City Council and with the support of the Canary Islands Government, and as part of its NATE project—will carry out in Palencia to mark the total solar eclipse on August 12, people with visual impairments will be offered the opportunity to follow the event through the Inclusive Eclipse project of the Institute of Space Sciences (ICE-ISIC). This option will be available at a designated location on the grounds of the Cristo del Otero monument. In this sound art space, anyone can enjoy the eclipse through sound

  • An overlay of the solar corona captured by the NATE team in Palencia during the total solar eclipse on 12 August, superimposed on the latest forecast produced a few hours before the eclipse by the IAC and the Predictive Science Inc group in California using the La Palma supercomputer
    The IAC and California-based Predictive Science Inc Predict the Solar Corona for the August 12 Eclipse Using the La Palma Supercomputer
    Ahead of the upcoming solar eclipse on August 12, the Instituto de Astrofísica de Canarias (IAC), in collaboration with the research group Predictive Science Inc. (PSI, San Diego, California), has successfully simulated in high detail the structure of the solar corona that will be visible during totality along the path of totality, including Palencia, where the IAC will gather more than 40 spanish, moroccan, and american astronomers. To process this complex three-dimensional calculation, the computing power of the supercomputing node )Supercomputador La Palma) was utilized, along with code

  • Hannah Thiel explica conceptos de comunicaciones cuánticas durante un curso del proyecto CELESTE en el IAC.
    Press release
    The IAC promotes training in quantum communications within the framework of the CELESTE project
    The course, taught by Hannah Thiel, a researcher at the Vigo Quantum Communication Center, brought Institute staff together around the foundations, applications and technological challenges of quantum communications and quantum key distribution. The Instituto de Astrofísica de Canarias (IAC) held a specialised course on quantum communications on 28 and 29 July, organised at the invitation of the Free Space Optics Communications Lab of the CELESTE project. The training, delivered by researcher Hannah Thiel, from the Vigo Quantum Communication Center at the Universidad de Vigo, took place at
