Four years ago, an international team (USA, Japan and Europe) carried out an unprecedented suborbital space experiment called CLASP-1, motivated by theoretical investigations carried out at the IAC by Javier Trujillo Bueno and his research group. After the outstanding success of that mission, a few days ago NASA has launched CLASP-2.

The bulk of stars in galaxy clusters are confined within their constituent galaxies. Those stars do not trace the extended distribution of dark matter well as they are located in the central regions of the cluster's dark matter subhaloes. A small fraction of stars is expected, however, to follow the global dark matter shape of the cluster. These are the stars whose extended spatial distribution results from the merging activity of galaxies and form the intracluster light (ICL). In this work, we compare the bi-dimensional distribution of dark matter in massive galaxy clusters (as traced by

2019 ha traído cambios a la Fundación Starlight y al Museo de la Ciencia y el Cosmos. En enero, Luis A. Martínez Sáez se despedía del cargo de director de la fundación que vela por la protección del cielo estrellado, la difusión de la Astronomía y la promoción, coordinación y gestión del movimiento Starlight. Cedía de esta manera el testigo a la astrofísica Antonia Varela Pérez, quien ha asumido ahora el cargo de directora, si bien anteriormente fue asesora, auditora y profesora de esta Fundación. Antonia Varela Pérez, doctora en Astrofísica e investigadora del IAC, es parte de la plantilla

The QUIJOTE experiment at the Teide Observatory (Tenerife) has studied the polarization of this type of emissions in one of the nearest and youngest star formation regions of the Milky Way, yielding important information for effectuating an adequate separation of this radiation from other galactic components.

An international study, using the high-speed HiPERCAM camera, installed in the Gran Telescopio Canarias (GTC), has determined for the first time the mass and radius of one of the oldest stars in our Galaxy.

The exhibition "100 Square Moons" is inaugurated in Brussels, together with a model of the European Solar Telescope. For a week the European Parliament in Brussels will be home to this educational display by the Instituto de Astrofísica de Canarias (IAC), while at the same time another copy of the exhibition is being shown in Japan.
