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. TheAdvertised on

In the 90s, the COBE satellite discovered that not all the microwave emission from our Galaxy behaved as expected. Part of this signal was later assigned to a fresh new emission component, spatially correlated with the Galactic dust emission, which showed greater importance in the microwave range of frequencies. It has been named since as “anomalous microwave emission”, or AME. The current main hypothesis to explain the AME origin is that it is emitted by small dust particles which undergo fast spinning movements. In Fernández-Torreiro et al. (2023), we study the observational properties ofAdvertised on

The annual meeting of the DALI (Dark-photons & Axion-Like particles Interferometer) experiment, an international collaboration to develop an astroparticle detector for the first direct observation of dark matter, was held on 7 and 8 February at the IAC headquarters in La Laguna. The various proofs of concept carried out over the last few years have given rise to a prototype, manufactured at the IAC's instrumentation facilities, whose first scientific results are expected to be published soon. The main goal of DALI is to search for dark matter axions and paraphotons in a spectral range thatAdvertised on
