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

An international team of astronomers, including researchers from the Instituto de Astrofísica de Canarias (IAC), the University of Liège and collaborators in UK, Chile, the USA, and Europe, has discovered a transiting giant planet orbiting the smallest known star to host such a companion — a finding that defies current theories of planet formation. The host star, TOI-6894 , is a red dwarf with only 20% the mass of the Sun , typical of the most common stars in our galaxy. Until now, such low-mass stars were not thought capable of forming or retaining giant planets. But as published today in

A team of researchers from the Instituto de Astrofísica de Canarias (IAC), collaborating with other international institutions, has managed to find new galaxies in the Spiderweb protocluster. This was possible thanks to the James Webb Space Telescope, which is a project of the space agencies of the United States (NASA), Europe (ESA) and Canada (CSA). Exploring the populations of galaxies, and discovering their physical properties in large scale structures helps astronomers to understand galaxy formation and how their assembly is determined by their environment.
