The IACTEC building, in the Las Mantecas Science and Technology Park in La Laguna, is hosting the 11th International Astronomy Education Adventure in the Canary Islands (AEACI 2026) this week. This edition forms part of the Erasmus+ Astro-Journeys project, co-funded by the European Union, in which the IAC is participating alongside eight other institutions from France, Portugal, Germany and Greece. The aim of the project is to support the professional development of teachers, enabling them to design interdisciplinary, inclusive and research-based learning experiences, using astronomy as the

The discovery, made in collaboration between the IAC Solar System Group and Light Bridges, reveals the rotation period of comet 3I/ATLAS The Two-metre Twin Telescope (TTT) has made a pioneering discovery in astronomy: the first detection of a jet of gas and dust and its periodic modulation in an interstellar comet, 3I/ATLAS. The study, published in the journal Astronomy & Astrophysics, provides the first evidence of localised activity from an interstellar nucleus, offering unique insight into the nature of a celestial body that formed outside our Solar System. An extraordinarily normal

El sistema telescópico de defensa planetaria ATLAS-Teide, instalado en el Observatorio del Teide por el Instituto de Astrofísica de Canarias (IAC) y parte de la red de telescopios ATLAS , detectó el pasado 11 de agosto a las 2:20 hora canaria un pequeño asteroide que pasó muy cerca de la Tierra tan sólo un día después, en la madrugada del 12 de agosto de 2026 (a la 1:50 hora Canaria). El objeto, designado oficialmente como 2026 PC6 por el Minor Planet Center, mide unos 10 metros, aproximadamente el tamaño de una guagua, y sobrevoló nuestro planeta pasando a tan solo 14.573 kilómetros de
