  • Low iron binary recreation

    An international team of researchers, among them scientists from the Instituto de Astrofísica de Canarias (IAC), has confirmed the primitive origen of an old star in the Milky Way, using the ESPRESSO instrument. The stars with the least content of metals are considered to be the oldest in the Milky Way, formed only a few hundred million years after the Big Bang, which is a small fraction of the age of the universe. These stars are “living fossils” whose chemical composition gives clues about the first stages of the evolution of the universe. The star SMSS1605-1443 was discovered in 2018 and

  • The Isaac Newton Group of Telescopes (ING) and the WEAVE instrument team present the first observations with this new instrument. This is a powerful latest generation multi-fibre spectrograph which, in synergy with the Gaia satellite of the European Space Agency (ESA), will be used to obtain spectra of several million stars in the disc and the halo of our Galaxy, permitting in-depth “archaeology” of the Milky Way. In addition, other galaxies, both nearby and distant, will be studied, some of them detected by the LOFAR radio telescope, in order to get to know their evolution. WEAVE, on the

  • Exo-Earths in GJ 1002

    An international scientific team led by researchers at the Instituto de Astrofísica de Canarias (IAC) has discovered the presence of two planets with Earth-like masses in orbit around the star GJ 1002, a red dwarf not far from the Solar System. Both planets are in the habitability zone of the star “Nature seems bent on showing us that Earth-like planets are very common. With these two we now know 7 in planetary systems quite near to the Sun” explains Alejandro Suárez Mascareño, an IAC researcher, who is the first author of the study accepted for publication in Astronomy & Astrophysics.

  • Webb's First Deep Field

    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

    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

  • Artist’s impression of an ultra-hot Jupiter transiting its star

    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
