The first image of a new gaseous component in a planetary nebula.
False color image of the planetary nebula NGC 6778. In blue, the emission associated with weak lines of ion O++ recombination, taken with the OSIRIS tunable filter blue instrument in the GTC. In green, emission of the same ion in the excited lines by coll

The smallest galaxies in the cosmos are emerging as one of the greatest challenges for modern astrophysics. A team of researchers from the Universidad de La Laguna and the Instituto de Astrofísica de Canarias (IAC) is studying these tiny systems to understand why they do not always match the predictions of the standard cosmological model. The work is carried out within the framework of the INGENIO project, funded by the Agencia Estatal de Investigación (AEI), which uses advanced cosmological simulations to reconstruct the galactic environment closest to the Milky Way and explore physical
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
Ultra-faint dwarf galaxies, among the tiniest and faintest galaxies known, may hold the key to understanding one of the Universe’s biggest mysteries: the true nature of dark matter. A new study reveals that even a single collision between dark matter particles every 10 billion years — roughly the age of the Universe — is enough to explain the dark matter cores observed in these small systems. These galaxies, which contain only a few thousand stars, are dominated by dark matter and have relatively simple evolutionary histories. That makes them ideal cosmic laboratories for testing theories
