The first image of a new gaseous component in a planetary nebula.
False color image of the planetary nebula NGC 6778. In blue, the emission associated with weak lines of ion O++ recombination, taken with the OSIRIS tunable filter blue instrument in the GTC. In green, emission of the same ion in the excited lines by coll

Asteroids are the remnants of the planetary formation in the Solar System and so, their study helps us to understand the conditions during the early stages of the formation of our planetary system. Among asteroids, those classified as primitives present similar spectra to that of carbonaceous chondrites, i.e., they are rich in carbon and organic compounds and silicates altered by the presence of liquid water (phyllosilicates). Primitive asteroids are well characterized in various wavelength regions, showing their most diagnostic feature at 3μm. However, there is a lack of information in the
The Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) have collaborated in the research that reveals the structure of 74 exocomet belts, it means, belts with minor bodies outside our solar system, around stars close to us. Astrophysicists led by a team from Trinity College Dublin , with the Universidad de La Laguna (ULL) and Instituto de Aastrofísica de Canarias (IAC) collaboration- have for the first time imaged a large number of exocomet belts around nearby stars, and the tiny pebbles within them. The crystal-clear images show light being emitted from these
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
