A pioneering study from the Instituto de Astrofísica de Canarias (IAC) which combines laboratory chemistry with astrophysics, has shown for the first time that grains of dust formed by carbon and hydrogen in a highly disordered state, known as HAC, can take part in the formation of fullerenes, carbon molecules which are of key importance for the development of life in the universe, and with potential applications in nanotechnology. The results are published as a Letter to the Editor in the prestigious journal Astronomy & Astrophysics. Fullerenes are carbon molecules which are very big

The IAC researcher Susana Iglesias-Groth has discovered the existence of tryptophan, an amino acid essential for the formation of proteins and the develoment of living organisms, within a stellar system in the Perseus Cloud. She did this using data from the Spitzer Space Observatory. The results of this finding are published in the journal Monthly Notices of the Royal Astronomical Society. Tryptophan is one of the 20 amino acids considered essential for the formation of proteins, which are key macromolecules for the development of life on Earth. This amino acid has many spectral features in

After comparative studies of a sample of almost 50 open stellar clusters of different ages in the Milky Way, research led by the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) with collaboration by the Polytechnic University of Cartagena, shows that when these star clusters age they lose the majority of their less massive members. This result confirms that there are internal dynamical processes in open clusters caused by their long journeys through the Galaxy, which bring about the expulsion of these low mass stars. The study, published in the journal
