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

La investigadora del Instituto de Astrofísica de Canarias (IAC) Julia de León, ha sido galardonada con el prestigioso Premio Mujeres a Seguir (MAS) 2024 en la categoría de Ciencia. La distinción reconoce su excepcional trayectoria, su impacto en la investigación Astrofísica y su papel como referente femenino en un sector estratégico. La ceremonia de la XII edición de los Premios Mujeres a Seguir se celebró este 30 de octubre en Madrid, reuniendo a personalidades de la política, la ciencia, la cultura y el deporte para rendir homenaje a mujeres que, con su talento y compromiso, están
Measuring galaxy sizes is essential for understanding how they were formed and evolved across time. However, traditional methods based on l ight concentration or isophotal densities often lack a clear physical meaning. A recent study from Trujillo+20 explores a more physically motivated definition: the radius R 1, where the stellar surface density falls to 1 solar masses per parsec square —roughly the threshold for gas to form stars in galaxies like the Milky Way. In this work, Arjona-Gálvez+25 uses over 1,000 galaxies from several state-of-the-art cosmological simulations (AURIGA, HESTIA
The Solar System research group at the Instituto de Astrofísica de Canarias (IAC) is participating in the international programme to keep a closet track of asteroid 2024 YR4. The aim is to determine its orbit with the highest possible precision before it stops being observable by ground based and satellite telescopes in April, and so improving our value of the probability that it will impact the Earth in 2032. In this context several telescopes of the Canary Observatories of the IAC are playing an outstanding role in this observing campaign: The Gran Telescopio Canarias (GTC) at the Roque de
