The Instituto de Astrofísica de Canarias (IAC) is demonstrating the quality and international relevance of the Canary Islands Observatories at the 245th session of the American Astronomical Society (AAS) meeting being held this week in Maryland (USA). This meeting, led by the American astrophysics community, brings together the world's most important research centres in this field to share lines of work and proposals for the present and the future. The IAC delegation in Maryland is headed by the director of the centre, Valentín Martínez Pillet, who is part of the panel of speakers with a

An international team, led by a researcher from the University of Liège (Belgium) affiliated to the Instituto de Astrofísica de Canarias (IAC), has discovered an extraordinarily light planet orbiting a distant star in our galaxy. This discovery, reported today in the journal Nature Astronomy, is a promising key to solving the mystery of how such giant, super-light planets form. The new planet, named WASP-193b, appears to dwarf Jupiter in size, yet it is a fraction of its density. The scientists found that the gas giant is 50 percent bigger than Jupiter, and about a tenth as dense — an

Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter present in the early universe into the sprawling strands of galaxies we see today. A new study using data from the Dark Energy Spectroscopic Instrument (DESI) has traced how this cosmic structure grew over the past 11 billion years, providing the most precise test to date of gravity at very large scales. DESI is an international collaboration of more than 900 researchers, included the Instituto de Astrofísica de Canarias (IAC), from over 70 institutions around the world and is managed by
