An international collaboration, with participation by the Instituto de Astrofísica de Canarias (IAC), has found a system of six exoplanets orbiting a central star with a precise rhythm.This phenomenon, known as orbital resonance, is common during the starting phase of planet formation, but it is exceptional to find a system with such a large set of planets which conserves this kind of gravitational synchronism. This finding shows that the system has not undergone major changes during its six billion year history, so that it gives an unusual view of the formation and evolution of planets. The

An international team of scientists, with participation by researchers at the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) have found a barred spiral galaxy, similar to the Milky Way, in the early universe, when it was only 15% as old as it is now. The galaxy, ceers-2112, is the most distant barred spiral observed, and its existence poses a challege to the current model of formation and evolution of galaxies. The discovery, made with the James Webb Space Telescope (JWST) is published in the journal Nature. In astrophysics studying the structure of galaxies

A team led by researchers from the Instituto de Astrofísica de Canarias (IAC) and the National Astronomical Observatory of Japan (NAOJ) has made, with the Gran Telescopio Canarias (GTC or Grantecan) and the Subaru telescope, the largest and deepest follow-up to date of a black hole collision previously detected in gravitational waves. The observations showed no optical signal in the direction of the phenomenon, which means that if this black hole merger emitted any light at all, it was fainter than the detection limit of these two telescopes and their instruments. This result imposes an
