From 18 to 20 October, scientists from the USA, Japan and Europe meet at the Instituto de Astrofísica de Canarias (IAC) to discuss the results of the third CLASP space experiment to study the magnetic field of the solar chromosphere and the science of future solar missions. Several years ago, an international scientific team began developing a series of novel suborbital space experiments, with the goal of measuring the intensity and polarization of the ultraviolet radiation of the Sun emitted from one of the outer layers of its atmosphere, the chromosphere, very close to the base of the

Between 27th August and 7th September the Shelios 2023 expedition tool a group of researchers and students at the south of Iceland and Greenland, where they set up two experiments to measure the natural darkness of the arctic night, and from where they broadcast the aurora borealis. Among the apparatus they installed is the autonomous MiNiO ( Meteo Nano Observatory) controller, developed by the Technological Institute for Renewable Energies (ITER), for the Interreg EELabs project, coordinated by the Instituto de Astrofísica de Canarias (IAC). As well as making people aware of the problems of

From today the new edition of the monographic magazine Paralajes, produced and edited by the IAC, is available in both digital and paper formats. This volume is on the theme of astronomy in the infrared, radiation outside the range visible to the human eye, very important in the history of the IAC, described in detail in over 170 pages. A major fraction of the energy emitted within the universe is in the infrared, but we cannot detect it except using instruments specially developed to do this. The IAC has been aware of this since its beginning, and has been developing infrared instruments
