A team from the Instituto de Astrofísica de Canarias (IAC) has quantified for the first time the impact that the motions of binary stars can have on estimates of dark matter in some of the smallest galaxies in the universe. The study proposes a new methodology that will make it possible to obtain more precise measurements of the amount of dark matter present in these systems. The Milky Way, our galaxy, contains hundreds of billions of stars. However, dozens of much smaller galaxies orbit around it, dwarf companions that host thousands of times fewer stars and live embedded within our galaxy

The International Astronomical Union (IAU) has approved the naming of asteroid (20747) Tanialepivert in honour of Tania Le Pivert Jolivet, a postdoctoral researcher at the Instituto de Astrofísica de Canarias (IAC), for her contributions to the study of primitive asteroids. The scientist thus joins the group of researchers affiliated with the IAC who have an asteroid named after them. Tania Le Pivert Jolivet, a postdoctoral researcher at the Instituto de Astrofísica de Canarias (IAC), has been honoured with one of the most unique accolades a person dedicated to the study of the Solar System

El Instituto de Astrofísica de Canarias (IAC) celebra en 2026 la octava edición consecutiva del proyecto Habla con Ellas: Mujeres en Astronomía, una iniciativa de divulgación científica y educación en astronomía que se desarrolla en el marco del Día Internacional de la Mujer y la Niña en la Ciencia (11 de febrero). Dirigido a la comunidad educativa, el proyecto tiene como objetivo visibilizar el papel de las mujeres en la astronomía y la astrofísica, crear referentes femeninos en ciencia y tecnología e inspirar vocaciones científicas, especialmente entre niñas y jóvenes interesadas en las
