On January 7, 2025, the European Commission established the Cherenkov Telescope Array Observatory (CTAO) as a European Research Infrastructure Consortium (ERIC), furthering its mission to become the world’s largest and most powerful observatory for gamma-ray astronomy. The creation of the CTAO ERIC will enable the Observatory's construction to advance rapidly and provide a framework for distributing its data worldwide, significantly accelerating its progress toward scientific discovery. “The ERIC will streamline the construction and operation of the Observatory in a way that will undoubtedly

This is the third “mini-Moon” with lunar-like material identified as part of the Arjuna asteroid belt, where objects follow similar orbits around the Sun to that of the Earth-Moon system. IAC, February 6, 2025. – Near-Earth asteroid 2024 PT5 orbits around the Sun following a trajectory very similar to that of the Earth-Moon system, and during two months of 2024, it accompained our Earth on its journey. This asteroid has material on its surface that was originated in the Moon, as it has been proved by a research led by the Insituto de Astrofísica de Canarias (IAC) and the Universidad

The international CTAO LST Collaboration , in which the Instituto de Astrofísica de Canarias (IAC) plays a prominent role, released remarkable findings from observations of GRB 221009A—the brightest gamma-ray burst (GRB) ever recorded. The results were published by the renowned journal The Astrophysical Journal Letters (ApJ Letters) . The publication presents in-depth observations conducted in 2022 with the Large-Sized Telescope (LST ) prototype, the LST-1, during its commissioning phase at the Roque de los Muchachos Observatory (ORM) on the CTAO-North site in La Palma, Spain.
