  • Artist's impression of LP 791-18 d

    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

  • Crescent Nebula (NGC 6888)

    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

  • Programa INVESTIGO

    On 28th April last, 11 people joined the Instituto de Astrofísica de Canarias through the "INVESTIGO Programme" for hiring young job seekers to carry out research and innovation initiatives, financed by the Canary Islands Employment Service through the Recovery, Transformation and Resilience Plan-Next Generation EU Funds. A welcoming ceremony was held in the classroom at the IAC Headquarters where the new staff was received by Alfonso López, coordinator of Instrumentation at the IAC, and Anselmo Sosa, manager of the Office of Transfer and Institutional Actions (OTAI). The different heads of

  • Comparison between a trail of stars and an edge-on galaxy IC5249

    A study carried out by a team of researchers at the Instituto de Astrofísica de Canarias (IAC) has shown that an unusual thin structure of stars, recently discovered by the Hubble Space Telescope, could be a galaxy seen edge-on. This finding goes against the original interpretation in which a fleeing supermassive black hole was leaving a trail of stars in its wake. The new interpretation is published in the journal Astronomy and Astrophysics Letters. A mysterious trail of stars formed eight thousand million years ago and recently discovered by the Hubble Space Telescope has been a challenge

  • Quasars interacting with other galaxies

    An international scientific team, including the researchers from the Instituto de Astrofísica de Canarias (IAC) Cristina Ramos Almeida, Patricia Bessiere and Giovanna Speranza, has discovered that quasars, some of the brightest and most powerful objects in the Universe, are mainly ignited by mergers between galaxies. The finding sheds new light, after years of controversy, on what causes the emission of large amounts of energy in the most powerful active nuclei. The research has used observations from the Isaac Newton Telescope (INT) and the William Herschel Telescope (WHT) at the Roque de

  • Galaxia diminuta RX J2129-z95

    Using first-of-their-kind observations from the James Webb Space Telescope (JWST), an international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, finds a unique, minuscule galaxy that emitted its light more than 13 billion years ago. The galaxy, detected through gravitational lensing, is one of the smallest ever discovered at this distance and has an extremely high star formation rate for its size. This discovery could help astronomers learn more about galaxies that were present shortly after the Universe came into existence. The paper is published in
