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

From 13 to 17 April 2026, the University of Groningen (The Netherlands) hosted the ExGal-Twin 2nd Radio Astronomy School and 2nd Project Meeting, key activities of the European project ExGal-Twin, coordinated by the Instituto de Astrofísica de Canarias (IAC). The event brought together researchers, students and technical staff from the IAC and the partner institutions: the Kapteyn Astronomical Institute (University of Groningen), the Institute for Computational Cosmology (Durham University), and the Observatoire Astronomique de Strasbourg (CNRS), reinforcing scientific collaboration and
