    The workshop “25 years of cooperation in optical technologies and future trends”, will take place next Monday, November 14th, at the Headquarters of the Instituto de Astrofísica de Canarias (IAC) with scientific and engineering staff from the IAC, and from ESTEC, the European Space Technology and Research Centre of the European Space Agency (ESA). At the meeting, the two institutions will present their work on optomechanical engineering and set out the basis for further collaboration. They will discuss, among other subjects, thermal techniques and optical instrumentation developments, cryo

  • The Subcommission of Scientific and Technical Affairs of COPUOS visits the IAC

    This week the Ambassadors, permanent representatives at the International Organizations with headquarters in Vienna, of Spain, Esther Monterrubio, and of Paraguay, Juan Francisco Facetti, were shown the installations of the IAC. During their stay they visited some of the scientific infrastructures of the Canary Islands Observatories (OCAN) and showed interest in the projects being developed there. Among the various duties of these two permanent Ambassadors is that of representing their countries in the United Nations Commission on the Peaceful Uses of Outer Space (COPUOS) and its two

    The European Research Council (ERC) has awarded an ERC Advanced Grant, funding for the development of research projects at the frontiers of knowledge, to the Professor of the Higher Council for Scientific Research (CSIC) Eduardo L. Martín Guerrero de Escalante, who is an active researcher at the Instituto de Astrofísica de Canarias (IAC). The project, entitled “Substellar Science with the Euclid Space Mission“ (SUBSTELLAR) has, as one of its main objectives, the use of data from the future space telescope Euclid to increase our knowledge of objects with substellar masses (brown dwarfs and

  • Results of the recent 2D model of CBPs. Left: temperature. Right: Image showing how the simulation would look like if observed with the Solar Orbiter mission in the extreme ultraviolet from space. The CBP is distinguished by the hot magnetic loops that appear bright in the right panel.

    When the Sun is observed in X-ray or extreme ultraviolet wavelengths, hundreds of bright and compact structures with a rounded shape and sizes similar to that of our planet Earth can be easily distinguished in the solar corona. These structures are known as Coronal Bright Points or CBPs and they consist of sets of magnetic loops that connect areas of opposite magnetic polarity on the solar surface. These loops confine the solar plasma and in them, by mechanisms that have been debated for many years among solar physicists, the gas remains with temperatures of several million degrees, emitting

  • 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

    El pasado sábado 1 de octubre tuvo lugar la segunda visita al Observatorio del Teide organizada por el programa #AmigosdelIAC, en el que algunos de los miembros de este programa pudieron conocer las instalaciones y observar el cielo a través de telescopios divulgativos. Si tienes interés en la labor del Instituto de Astrofísica de Canarias y aún no eres “Amigo del IAC”, puedes unirte a nuestro Programa respondiendo esta breve encuesta (, sin necesidad de que realices ninguna aportación. #AmigosdelIAC #IACastrofísica #InstitutodeAstrofísicadeCanarias #IAC #Tenerife
