An investigation carried out by the astrophysicists of the Instituto de Astrofísica de Canarias (IAC) Žofia Chrobáková, a doctoral student at the IAC and the University of La Laguna (ULL), and Martín López Corredoira, questions one of the most interesting findings about the dynamics of the Milky Way in recent years: the precession, or the wobble in the axis of rotation of the disc warp is incorrect. The results have just been published in The Astrophysical Journal.

The International Scientific Committee (CCI for its initials in Spanish) of the Canary Observatories has given the go-ahead for the siting of the installation of the European Solar Telescope (EST) at the Roque de Los Muchachos Observatory (Garafía, La Palma). The decision, taken at the first of the biannual meetings of the Committee, held virtually, implies the construction of the largest European infrastructure dedicated to solar observations, and the strengthening of the position of the Canaries as the place with the largest concentration of solar telescopes in the world.

Registration is now open for the training course "PETeR: Investigating the Universe with robotic telescopes", which will take place between 25 May and 3 June for teachers in the Canary Islands, and between 26 May and 10 June for teachers in the rest of Spain. One of the main objectives of the Educational Project with Robotic Telescopes (PETeR) of the Instituto de Astrofísica de Canarias (IAC) is to train teachers and educators in astronomy and in the use of robotic telescopes as tools for students to develop their scientific and technological skills through guided research projects. In the

João Mira-Gomes, Portuguese Ambassador to Spain, visited the Instituto de Astrofísica de Canarias (IAC) headquarters in La Laguna this morning, together with Vicente M. Álvarez Gil, Portuguese Consul in Santa Cruz de Tenerife, and several members of his team, accompanied by Rafael Rebolo, Director of the IAC, and Mahmoudreza Oshagh, senior postdoctoral researcher. During their tour of the facilities, they were informed about the different projects that are being developed in the framework of the Portuguese-Spanish collaboration. The IAC participates in several consortiums and scientific

A recent study analyses data collected at 44 of the darkest places in the world, including the Canary Island Observatories, to develop the first complete reference method to measure the natural brightness of the night sky using low-cost photometers. Of the 44 photometers in the survey, the Roque de los Muchachos Observatory (Garafía, La Palma, Canary Islands) stands out at the darkest of all the skies analysed. The night sky is not completely dark; even in the remotest places there is a glow in the sky produced by natural components, both terrestrial and extraterrestrial, and by artificial
