An international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, has discovered the extremely eccentric orbit of a gas giant exoplanet. This world, called TIC 241249530 b, not only follows one of the most drastically stretched-out orbits of all known transiting exoplanets, but also is also orbiting its star backwards, lending insight into the mystery of how these high-mass gas giants evolve into hot Jupiters , with very close and circular trajectories. The study is published in Nature. Within the population of known exoplanets, there are those that

On Wednesday 30 October, the headquarters of the Instituto de Astrofísica de Canarias (IAC) received a talk by the first Swiss astronaut, Claude Nicollier, who wanted to share his experience in space with the personnel of the IAC. Claude Nicollier is the first Swiss astronaut to have flown into space. After his studies at the Universities of Geneva and Lausanne, Claude joined ESA as a member of their first group of astronauts. Since 2007 Nicollier has been a Professor at the Federal Polytechnical School at Lausanne. He has spent more than 1000 hours in space (more than 42 days) including a

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
