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.

An international team of scientists, with participation by researchers at the Instituto de Astrofísica de Canarias (IAC), has discovered a very large, but thin, stream of stars in the Coma cluster of galaxies. This is the largest stream of stars detected until now, and the first to be found in a cluster of galaxies. This finding, which is published in the journal Astronomy and Astrophysics, was made using observations taken with the William Herschel Telescope (WHT) at the Roque de los Muchachos Observatory (Garafía, La Palma, Canary Islands). The Coma Cluster is a large cluster of galaxiesAdvertised on
