The Euclid mission of the European Space Agency (ESA) will be launched into space tomorrow, 1st July to make the largest and most precise 3D map of the Universe. Spain has an important role in this project, where it is part of the the Consortium which has driven the mission since its origin. Spain has also participated significantly in the instrument design of the project, and will contribute to its scientific use. The Instituto de Astrofísica de Canarias (IAC) has collaborated in the design, construction and testing of the control electronics for one of the on-board instruments. It also

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

After a break of 4 years, on June 23rd and 24th the Teide Observatory will be celebrating its Open Days. This activity is free; its aim is to bring some knowledge of astronomy to the general public, including those people who happen to be visiting the island on those two days. To make a visit it is essential to register using a special form before June 16th. In this year’s edition the activity will be guided, and 9 points of interest will be visited, one every 20 minutes, so that the complete visit should take 3 hours, from 10:00 to 13:00 for the morning session, and from 16:00 to 19:00 for
