In the Museo de la Ciencia del Cosmos Boris Gänsicke will unravel the puzzle of how planetary systems will end

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 IAC, have performed a unique cosmic test - measuring the mass of an ancient star using two entirely different methods, finding agreement to within just 1.4%. This result marks a milestone in our ability to determine the ages of old stars and use them as living fossils to study the Milky Way’s distant past. The team analysed the red giant in the binary system KIC 10001167 using two independent approaches: firstly, by measuring the brightness and radial velocity variations due to the orbital motion of the binary, and secondly
