Yesterday, 30 October 2023, from the telescope itself at the Roque de los Muchachos Observatory on the island of La Palma, the WEAVE instrument, a powerful state-of-the-art multi-fibre spectrograph, was publicly unveiled. The inauguration ceremony brought to La Palma the leaders of the science funding agencies from the partner countries of the Isaac Newton Group of Telescopes (ING), as well as a strong representation from the 500 members of the science teams and the organisations involved in the design and construction of WEAVE, making it the largest ever gathering of people inside the dome

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

From Monday 23rd to Thursday 26th October, the first meeting of the large astronomical observatories in Spain will be held in the town of Los Cancajos, La Palma. Most of them are scientific projects belonging to the map of the Singular Scientific-Technical Facilities (ICTS) of Spain, grouped in the field of Astrophysics under the coordination of the Astronomy Infrastructure Network (RIA). In this first edition, the participants are the Centro Astronómico Hispano en Andalucía (CAHA), the Gran Telescopio de Canarias (GRANTECAN), the Institute de Radiaoastronomie Millimétrique (IRAM), the
