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

An international team of astronomers, including researchers from the Instituto de Astrofísica de Canarias (IAC), the University of Liège and collaborators in UK, Chile, the USA, and Europe, has discovered a transiting giant planet orbiting the smallest known star to host such a companion — a finding that defies current theories of planet formation. The host star, TOI-6894 , is a red dwarf with only 20% the mass of the Sun , typical of the most common stars in our galaxy. Until now, such low-mass stars were not thought capable of forming or retaining giant planets. But as published today in
