  • Project video cover
    The IAC presents the video of the POLMAG project

    The IAC presents a public outreach video about the project “Polarized Radiation Diagnostics for Exploring the Magnetism of the Outer Solar Atmosphere” (POLMAG). In this video, several POLMAG scientists explain the basic aspects of the project. The POLMAG research group was created in January 2018 within the framework of the Advanced Grant awarded by the European Research Council (ERC) to Javier Trujillo Bueno (CSIC Research Professor and IAC Senior Scientist). POLMAG aims at novel advances in the development and application of polarized radiation diagnostic methods for exploring the magnetic

    A huge superbubble observed in an interacting galaxy

    Research led by Artemi Camps, who started it while he was studying for his doctorate in the Instituto de Astrofísica de Canarias and the University of La Laguna, and is now working at the Instituto de Astronomía of the UNAM (México) has discovered an expanding bubble in the disc of a galaxy. With a diameter of 15,000 light years, it is the largest bubble of its type observed in any galaxy. The study has recently been published in the journal Monthly Notices of the Royal Astronomical Society. A galaxy like the Milky Way is made up of hundreds of thousands of millions of stars, with a mixture

  • A realistic artist’s impression of WASP-76b atmosphere
    Observed: an exoplanet where it rains iron

    Nature magazine is publishing today a surprising study about the giant, ultra-hot planet WASP-76b in which researchers from the Instituto de Astrofísica de Canarias (IAC) have taken part. This exoplanet, 390 light years away towards the constellation Pisces, has days when its surface temperatures exceed 2,400 Celsius, sufficiently hot to evaporate metals. Its nights, with strong winds, cool down the iron vapour so that it condenses into drops of iron. This is the first result with the high resolution spectrograph ESPRESSO, an instrument co-directed by the IAC and installed on teh Very Large

  • Artistic impression of one of the SPECULOOS telescopes, with the binary brown dwarf eclipsing in the sky
    Observed: an occultation of a brown dwarf by another

    An international team of astronomers in the project SPECULOOS, dedicated to the search for habitable planets, with scientists participating from the Instituto de Astrofísica de Canarias (IAC) has discovered an eclipse (termed an occultation) in a peculiar brown dwarf formed by two stars orbiting around each other. The results are just published in the journal Nature Astronomy. The finding was by chance, when the scientists were working on the results from the first light of one of the four telescopes of the project, in Chile. Shortly after the building of the first SECULOOS telescopes, and

  • Pulsating star in binary system
    Astronomers discover a pulsating teardrop-shaped star

    An international team of astronomers, including researchers from the Instituto de Astrofísica de Canarias, has found for the first time an unusual star that oscillates on one side due to the gravitational attraction of another nearby star. The study, which is published in the journal Nature Astronomy, uses data from NASA's TESS satellite and has involved the collaboration of citizen scientists.
