The Catholic University of Louvain, in collaboration with the Instituto de Astrofisica de Canarias and the University of La Laguna, leads the first Asteroseismological study of high mass stars, using NASA telescopes.

Last Monday the GTC observed the asteroid 2019 DS1 in the context of a collaborative programme between the Instituto de Astrofísica de Canarias (IAC) and the European Space Agency (ESA) in which researchers from the Solar System group at the IAC are participating.

The OSIRIS instrument on the Gran Telescopio Canarias (GTC) has discovered, on the spiral galaxy Messier 106, a system of globular clusters whose unusual distribution and motion, wich could be a relic from the the “cosmic noon”.

200 nights of observation were needed, from both northern and southern hemispheres, to complete the biggest panorama of our Galaxy, the Milky Way. This IAC project, funded by the FECYT, has obtained the biggest panoramic image ever taken of our Galaxy without the use of professional telescopes.

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
