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 low

A greedy white dwarf star in our own Milky Way galaxy is devouring its closest celestial companion at a rate never seen before, according to an international study involving the Instituto de Astrofisica de Canarias (IAC) and the University of La Laguna (ULL). The research, published in the journal Monthly Notices of the Royal Astronomical Society , found the double star, named V Sagittae, is burning unusually bright as the super-dense white dwarf is gorging on its larger twin in a feeding frenzy. Experts think the stars are locked in an "extraterrestrial tango" as they orbit each other every

The team led by Claudia Gutiérrez from the ICE-CSIC and IEEC has used the Gran Telescopio Canarias (GTC) and the Nordic Optical Telescope (NOT), at the Roque de Los Muchachos Observatory, of the Instituto de Astrofísica de Canarias (IAC), in La Palma. The CSS161010 burst reached its maximum brightness in just 4 days in a small galaxy 500 million light-years away from us. An international scientific team, led by the Institute of Space Studies of Catalonia (IEEC) and the Institute of Space Sciences (ICE-CSIC), has managed to detect an exceptionally fast and bright cosmic burst in a small
