The Instituto de Astrofísica de Canarias (IAC) is actively participating in the observation of object 3I/ATLAS (C/2025 N1 ATLAS), initially included as A11pl3Z in the confirmed list of Near-Earth Objects (NEOs) of the International Astronomical Union's Minor Planet Centre (IAU/MPC). The object, which has been shown to be the third interstellar object detected in our solar system, was discovered by one of the telescopes in the ATLAS network for the detection and early warning of asteroids on an Earth-impact trajectory. The IAC is part of this network with its new telescope structure, ATLAS

This week, CTAO Managing Director, Stuart McMuldroch, and Construction Programme Manager, Volker Heinz, traveled to the Canary Islands for a productive visit with the hosting partners at the Instituto de Astrofísica de Canarias (IAC) and colleagues from the CTAO Large-Sized Telescope (LST) Collaboration. The team was warmly welcomed at the IAC Headquarters in Tenerife by IAC Director, Valentín Martínez, marking the first official meeting between the two directors since Valentín recently assumed this role. Hosted by Ramón García López, Principal Investigator of the CTAO group at the IAC, the

The Solar System research group at the Instituto de Astrofísica de Canarias (IAC) is participating in the international programme to keep a closet track of asteroid 2024 YR4. The aim is to determine its orbit with the highest possible precision before it stops being observable by ground based and satellite telescopes in April, and so improving our value of the probability that it will impact the Earth in 2032. In this context several telescopes of the Canary Observatories of the IAC are playing an outstanding role in this observing campaign: The Gran Telescopio Canarias (GTC) at the Roque de
