    ESPRESSO puts the physical constants to the test
    Why does gravity have the strength it has? What exactly determines the value of the electromagnetic force? Are the laws of Physics the same in any part of the universe and at any instant in time? Measurements made with the ESPRESSO high resolution spectrograph on the Very Large Telescope (VLT) have permitted the determination of one of the fundamental constants of Physics when the universe was only 40% of its present age, helping to find an answer to one of these questions. The study, in which a leading group of researchers from the Instituto de Astrofísica de Canarias (IAC) participated, is

    Diana Morant presides over the Governing Council of the IAC
    The Minister of Science and Innovation presided, this morning, over the annual meeting of the Governing Council of the Instituto de Astrofísica de Canarias (IAC) in the IACTEC building in La Laguna. In a press conference she stressed the support of the Government for the people of La Palma, and recognized the technological and research activity of the Institute during the pandemic. As well as the minster, other attendees at the meeting were Raquel Yotti Álvarez, Secretary General for Research, Elena Máñez Rodríguez, Coucillor of the Canary Government for Economy, Knowedge and Employment

    The “last breaths” in the lives of galaxies
    A team of astronomers has discovered that galaxies with an Active Galactic Nucleus (AGN) –hosting continuously growing black holes that emit large amounts of energy and radiation– may undergo a period of rapid star birth before shutting down completely. The research, conducted by astronomers from the Instituto de Astrofísica de Canarias (IAC), the University of Southampton and the Institute of Space Sciences, ICE (IEEC- CSIC) , was published in Monthly Notices of the Royal Astronomical Society: Letters. The Universe is filled with trillions of galaxies, each one comprising billions of stars

    Geminids 2021: the last wishes of the year
    During the nights of 12th and 13th of December we will enjoy the peak of the Geminid meteor shower. This will be broadcast live from the Teide Observatory (Tenerife) via the sky-live.tv channel, with the collaboration with the Energy Efficiency Labs (EELabs) project, of the Instituto de Astrofísica de Canarias (IAC). During the past decade the Geminids have always bid farewell to the year by producing over 100 meteors per hour (Zenith Hourly Rate, ZHR. In 2020 produce over 130 meteors/hour) which puts them in the annual front rank of meteor showers, together with the Perseids and the

    Astronomers discover an ultra-light and super-fast sub-Earth orbiting a red dwarf
    An international team, including researchers from the Instituto de Astrofísica de Canarias (IAC), has discovered an extrasolar planet with half the mass of the Earth that takes approximately eight hours to orbit its parent star, a red dwarf just under 31 light-years from Earth. Called GJ 367 b, it is one of the lightest among the nearly 5.000 exoplanets known today. With a diameter of just over 9000 kilometres, this sub-Earth is slightly larger than Mars. The discovery not only demonstrates that it is possible to precisely determine the event the smallest, least massive exoplanets, but also

    Study reveals that giant planets could reach "maturity" much earlier than previously thought
    An international team of scientists, in which researchers from the Instituto de Astrofísica de Canarias (IAC) participate together with other institutions from Spain, Italy, Germany, Belgium, UK, and Mexico, has been able to measure the masses of the giant planets of the V1298 Tau system, just 20 million year old. Masses for such young giant planets had not been obtained previously, and this is the first evidence that these objects have already reached their final size at very early stages of their evolution. For this study they have used radial velocity measurements from the HARPS-N
