    Holly R. Gilbert awarded the inaugural Irene González Hernández Prize in Solar Physics
    The award, instituted in honour of Canary Island scientist Irene González Hernández, recognises excellence in solar research and scientific leadership. The Instituto de Astrofísica de Canarias (IAC) celebrates the awarding of the inaugural Irene González Hernández prize to Dr. Holly R. Gilbert, director of the High Altitude Observatory (HAO) of the National Center for Atmospheric Research (NCAR) of the US National Science Foundation. The award was presented at the 56th meeting of the Solar Physics Division (SPD) of the American Astronomical Society (AAS), held jointly with the AAS and the

    P-CORONA: A New Tool for Calculating the Intensity and Polarization of Coronal Lines in 3D Models of the Solar Corona
    The solar corona—the outermost layer of the Sun’s atmosphere—is extremely hot and very low in density. One of the main challenges in solar physics is understanding why the corona reaches temperatures of over a million degrees. This heating is believed to be closely related to the Sun’s magnetic field. However, quantifying the coronal magnetic field is difficult because the light emitted by the corona is extremely faint, and its polarization signals, which encode the information on the magnetic field, are subtle. Thanks to recent advances in technology, telescopes like the Daniel K. Inouye

    Press release
    Gran Telescopio Canarias observations confirm that Hayabusa2's asteroid target is smaller and faster than expected
    Astronomers have used telescopes around the world, includingthe Gran Telescopio Canarias (GTC or Grantecan) at the Roque de los Muchachos Observatory on La Palma, to study the asteroid 1998 KY26, revealing it to be almost three times smaller and spinning much faster than previously thought. The asteroid is the 2031 target for Japan’s Hayabusa2 extended mission. The new observations offer key information for the mission’s operations at the asteroid. “We found that the reality of the object is completely different from what it was previously described as,” says astronomer Toni Santana-Ros, a
