This week, the Instituto de Astrofísica de Canarias is hosting the Second SONG Scientific Congress to conclude the first decade of high-level work of this international network devoted to the study of the interior of stars and the planetary systems that surround them. The meeting, which is taking place at the headquarters of IACTEC in La Laguna from 18 to 20 September, brings together more than 50 scientists from Europe, the United States, Australia and China to discuss the latest state-of-the-art techniques in time-resolved spectroscopy and stellar astrophysics.

The Instituto de Astrofísica de Canarias (IAC) and the KU Leuven , Belgium, have amplified their framework of collaboration in astrophysical research. The two institutions have signed an agreement which gives continuity to the operations of the Mercator Telescope at the Roque de los Muchachos Observatory (ORM), which started in 2002, and whose work will be strengthened by the installation of a new instrument called MARVEL (Mercator Array for Radial Velocities). Mercator is a semi-robotic telescope with a 1.2 metre primary mirror. Its name comes from that of the famous Flemish cartographerAdvertised on

Omega Centauri is a large globular cluster, containing almost ten million stars, in the direction of the constellation of Centaurus, which has been studied to understand its stellar kinematics, the motions of its stars under the action of the gravitational forces which act on them. A research team at the Instituto de Astrofísica de Canarias (IAC) has just published a study which shows that a group of black holes dominates the movements of its stellar kinematics. This result can be extended to certain other structures in the universe and goes against some previous claims about the role of lowAdvertised on
