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

An international piece of research, led by the Instituto de Astrofísica de Canarias (IAC) has found clues to the nature of some of the brightest and hottest stars in our Universe, called blue supergiants. Although these stars are commonly observed, their origin has been an old puzzle that has been debated for several decades. By simulating novel stellar models and analysing a large data sample in the Large Magellanic Cloud, IAC researchers have found strong evidence that most blue supergiants may have formed from the merger of two stars bound in a binary system. The study is published in the

The Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) have collaborated in the research that reveals the structure of 74 exocomet belts, it means, belts with minor bodies outside our solar system, around stars close to us. Astrophysicists led by a team from Trinity College Dublin , with the Universidad de La Laguna (ULL) and Instituto de Aastrofísica de Canarias (IAC) collaboration- have for the first time imaged a large number of exocomet belts around nearby stars, and the tiny pebbles within them. The crystal-clear images show light being emitted from these
