    Grantecan helps reveal how the black hole in the supergiant galaxy M87 shapes its mysterious filaments
    An international team of astronomers has captured the most detailed and completed view yet of the mysterious filaments surrounding the giant galaxy M87. Using new observations from the Gran Telescopio Canarias and the Canada-France-Hawaii Telescope, the study reveals how these long, thread-like structures move, evolve, and interact with their galactic environment and the activity of the central supermassive black hole. These findings have just been published in Monthly Notices of the Royal Astronomical Society. M87: a giant galaxy and its mysterious threads M87, located about 55 million

    Photonic integrated circuits for astronomy: A formal description of an integrated photonics-based wavefront sensor (IP-WFS)
    Solar wavefront sensing has been a challenge for astrophysical instrumentalists, due to the low contrast between the Sun and the sky background compared to night-time observations, which limits the performance of adaptive optics systems. Wavefront correction in solar physics requires the analysis of extended images; meanwhile, at night the displacement of a punctual object is analysed. This technique limits the spatial resolution, and therefore the accuracy in the wavefront reconstruction. To solve this problem, a new method of direct wavefront sensing without the need for image formation

    A study reveals the strongest evidence to date of a magnetic field on an exoplanet
    The Instituto de Astrofísica de Canarias (IAC) is taking part in an international study, published in the journal "Science", which provides the first conclusive evidence of a planet’s influence on the behaviour of its star. The results have made it possible to detect and estimate the strength of the magnetic field of the exoplanet GJ 436 b, opening up a new avenue for studying the habitability of planets outside the Solar System. Magnetic fields play a fundamental role in the habitability of planets. On Earth, the magnetic field acts as a shield against the solar wind and contributes to the
