Research led by the University of Oxford and with the participation of the Instituto de Astrofísica de Canarias (IAC) has succeeded in studying, for the first time, the tiny dust molecules known as polycyclic aromatic hydrocarbons (PAHs) in the nuclear region of luminous active galaxies. This work is one of the first studies to use spectroscopic data from the James Webb Space Telescope's (JWST) mid-infrared instrument (MIRI). Observing PAH molecules in the innermost regions of the galaxy is one of the best ways to study the influence of the central black hole in the evolution of the host

Fifteen students from nine different countries attended a meeting from September 26th to 30th to learn about the measurement of the fundamental properties of stars, how to access the publicly available data used to make these measurements as well as the tools and software involved. The Erasmus+ school "Eclipsing binaries and asteroseismology: Precise fundamental stellar parameters in the golden age of time-domain astronomy" was held in a hybrid format with fifteen students attending in-person and a further fifty via video conference. The latest advances in multi-epoch photometry and

Scientists and engineers from the institutions making up the consortium for building the EST have met in La Palma to evaluate the end of the preparatory phase. The European Solar Telescope (EST) project has finished the preliminary design phase of the sistemas and subsystems for what will be the largest solar telescope in Europe, in the framework of the european project PRE-EST. With its primary mirror of 4.2 metres diameter, the EST will be a unique driving force for solar research in Europe. It is planned to start construction in 2024, in the Roque de los Muchachos Observatory (La Palma

The prestigious journal Annual Review of Astronomy and Astrophysics invites two researchers from the Instituto de Astrofísica de Canarias (IAC) to publish an article reviewing the most important advances in the study of the magnetic fields in the outer regions of the solar atmosphere. Every year, the editorial committee of the journal Annual Review of Astronomy and Astrophysics (ARAA) meets to decide which researchers to invite to prepare their reviews, one for each field in Astrophysics. One of the 12 articles of the recently published volume 60 has been written by the IAC researchers

International research, led by the Instituto de Astrofísica e Ciências do Espaço (IA) and with the participation of the the Instituto de Astrofísica de Canarias (IAC), has confirmed the discovery of five exoplanets in the same planetary system, two of them similar to Mercury. The finding provides clues about how these unusual, very high-density planets form. The study is published today in the journal Astronomy & Astrophysics. An international science team has found a system orbiting the cool star HD 23472 with three super-Earths and two super-Mercuries. "We wanted to observe this planetary
