A recent study, entirely done by researchers at the Instituto de Astrofísica de Canarias (IAC) has produced the most complete analysis to date of the intracluster light, the diffuse and faint light emitted by stars in galaxy clusters which are not gravitationally bound to any galaxy. This result was based on data obtained by the new James Webb Space Telescope (JWST). The research gives new clues about the formation processes of galaxy clusters, and the properties of dark matter. The article was published in the specialized journal The Astrophysical Journal Letters . In clusters of galaxies

This Friday 2nd December at 17.30 will take place the public lecture “Challenges of Astrophysics and Cosmology”, which will tackle the role of technology in the comprehension of exoplanets, stellar formation and dark holes, among others, and the new questions that arise with the advancement of knowledge. The rendezvous is at the lecture theatre of the Museo de la Ciencia y el Cosmos, La Laguna (Tenerife). Malcolm Longair (Cavendish Laboratory, University of Cambridge) will give this public lecture on the occasion of the XXXIII Canary Islands Winter School - Overlaps at the Frontiers of

From 21th November till 2nd December at the Museo de la Ciencia y el Cosmos (San Cristóbal de La Laguna), and organised by the Instituto de Astrofísica de Canarias The 33rd edition of the Winter School of the Instituto de Astrofísica de Canarias will focus on the efforts of astrophysics, cosmology and particle physics to understand the mysteries of the dark universe. The XXXIII Canary Islands Winter School of Astrophysics, which is taking place between November 21st and December 2nd, was inaugurated yesterday in the Museo de la Ciencia y el Cosmos, with a welcome address by Rafael Rebolo

An international team of astronomers, in which IAC researchers participate, have discovered barium, the heaviest element ever found in an exoplanet atmosphere. It has been discovered at high altitudes in the atmosphere of the exoplanets WASP-76 b and WASP-121 b, two ultra-hot gas giants. The unexpected discovery, made possible by the ESPRESSO instrument at the European Southern Observatory's Very Large Telescope (ESO's VLT), raises questions about what these exotic atmospheres may look like. WASP-76 b and WASP-121 b are no ordinary exoplanets. Both are referred to as ultra-hot Jupiters as

Fifteen students from nine different countries attended a meeting from September 26th to 30th to learn about the measurement of the fundamental properties of stars, how to access the publicly available data used to make these measurements as well as the tools and software involved. The Erasmus+ school "Eclipsing binaries and asteroseismology: Precise fundamental stellar parameters in the golden age of time-domain astronomy" was held in a hybrid format with fifteen students attending in-person and a further fifty via video conference. The latest advances in multi-epoch photometry and
