An international collaboration, with participation by the Instituto de Astrofísica de Canarias (IAC), has found a system of six exoplanets orbiting a central star with a precise rhythm.This phenomenon, known as orbital resonance, is common during the starting phase of planet formation, but it is exceptional to find a system with such a large set of planets which conserves this kind of gravitational synchronism. This finding shows that the system has not undergone major changes during its six billion year history, so that it gives an unusual view of the formation and evolution of planets. The

The Instituto de Astrofísica de Canarias (IAC) is joining in the celebrations for 11 February by taking part in more than a dozen actions aimed at promoting scientific and technological vocations among girls and young women and making the role of women in the development of science more visible. The report " Radiography of the gender gap in STEAM education" published in 2022 by the Equality Unit of the Ministry of Education and Vocational Training shows that in some key disciplines for the future and, in particular, those related to Astronomy and Astrophysics, progress is not being made

An international piece of research, led by the Instituto de Astrofísica de Canarias (IAC) has found clues to the nature of some of the brightest and hottest stars in our Universe, called blue supergiants. Although these stars are commonly observed, their origin has been an old puzzle that has been debated for several decades. By simulating novel stellar models and analysing a large data sample in the Large Magellanic Cloud, IAC researchers have found strong evidence that most blue supergiants may have formed from the merger of two stars bound in a binary system. The study is published in the
