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

The Instituto de Astrofísica de Canarias (IAC) announces the arrival of the Astronomy on Tapinternational talk series in Spain, with its very first edition to be held in Tenerife. This outreach initiative, which was created in the United States and has since expanded worldwide, will now take place in the Canary Islands under the name "Astronomy on Tap – Canary Islands” and the local nickname “AstroTragos,” and is carried out within the framework of the EDUCADO and ExGal-Twin projects at IAC.

El Observatorio del Teide recibe este fin de semana a cerca de 1.000 visitantes en sus tradicionales Jornadas de Puertas Abiertas, organizadas por el Instituto de Astrofísica de Canarias (IAC) con motivo del solsticio de verano. Esta iniciativa, ya consolidada en el calendario divulgativo del IAC, ofrece a la ciudadanía la oportunidad de acercarse a la ciencia y a las infraestructuras científicas de Canarias de forma directa y cercana. La actividad está coordinada conjuntamente por el propio Observatorio y por la Unidad de Comunicación y Cultura Científica (UC3) del IAC, en el marco de las
