    The effects of light pollution on astronomy are increasing
    The Director of the Starlight Foundation, and researcher at the Instituto de Astrofísica de Canarias Antonia M. Varela Pérez has contributed to a monographic edition of the prestigious journal Science dedicated to light pollution and its consequences. The starry sky has been a source of inspiration throughout human history. Astronomy has been a common element in all cultures and civilizations, and has been used to establish calendars, to navigate and discover new lands, and to drive many scientific and technical advances. The article “The increasing effects of light pollution on professional

    Astronomers study the magnetic chaos of galaxies in the nearby Universe
    International research, with the participation of the Instituto de Astrofísica de Canarias (IAC), reveals that perturbations in the magnetic fields of galaxies may be related to star formation. The study has mapped the magnetic fields of about fifteen galaxies in the vicinity of the Milky Way. The data were obtained with the HAWC+ instrument on board SOFIA, an airborne infrared telescope on a Boeing 747 that was operational until September 2022. The results are published in The Astrophysical Journal. For decades, astronomers have studied the forces that govern the interior of galaxies -

    Nearly Two Million Objects to Study Dark Energy with DESI
    The first batch of data from the Dark Energy Spectroscopic Instrument is now available for researchers to mine. Taken during the experiment’s “survey validation” phase, the data include distant galaxies and quasars as well as Milky Way stars. The universe is big, and it’s getting bigger. To study dark energy, the mysterious force behind the accelerating expansion of our universe, scientists are using the Dark Energy Spectroscopic Instrument (DESI) to map more than 40 million galaxies, quasars, and stars. Today, the collaboration, which includes the Instituto de Astrofísica de Canarias (IAC)

    Evidence of water found in the atmosphere of an ultra-hot gas giant
    Using observations from the James Webb Space Telescope (JWST), an international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, has identified water vapour in the atmosphere of WASP-18 b, a massive extrasolar planet, a so-called hot Jupiter, with a temperature of around 2.700 °C. The result is published in the journal Nature. Exoplanet WASP-18 b is about 400 light-years from Earth, is 10 times more massive than Jupiter and has an orbital period of less than a day. Its extreme proximity to its star, its relative closeness to Earth, and its large mass

    Astronomers find Earth-sized world potentially covered in volcanoes
    An international research, with the participation of the Instituto de Astrofísica de Canarias (IAC), has discovered an Earth-size exoplanet that may be carpeted with volcanoes. Called LP 791-18 d, the planet could undergo volcanic outbursts as often as Jupiter’s moon Io, the most volcanically active body in our solar system. The study is published in the scientific journal Nature. LP 791-18 d orbits a small red dwarf star about 90 light-years away in the southern constellation Crater. The team estimates it’s only slightly larger and more massive than Earth. Astronomers already knew about two

    An old problem about the measurement of the chemical composition of the universe has been resolved
    Research carried out by a scientific team from the University of Heidelberg (UH), the Instituto de Astrofísica de Canarias (IAC) and the National Autonomous University of Mexico (UNAM) has allowed them to solve the abundance discrepancy, a puzzle over 80 years old, about the chemical composition of the Universe. They find that the effect of the variations in temperatura in the large gas clouds where stars are born has led to the underestimation of the quantity of heavy elements in the Universe. The results have been published in the prestigious journal Nature . All the stars are born, live
