An international research team, with participation by the Instituto de Astrofísica de Canarias (IAC) shows that the satellite galaxy NGC 5195 has passed twice through the disc of the Whirlpool Galaxy (M51), in relatively recent times, stimulating star formation, and defining the structure of its arms. The research is published in the prestigious The Astrophysical Journal. The Whirlpool Galaxy M51, is a ”grand design” spiral galaxy: its spiral form is dominated by two well defined arms. Discovered by Charled Messier in 1771 M51 lies some 31 million light years from Earth, As it is face-on

Research, in which the Instituto de Astrofísica de Canarias has participated has analyzed object 2023 FY3, a member of a group of asteroids which have trajectories similar to that of the Earth. The available data suggest that it could collide with the Earth during the next hundred years, but its small size implies that it is not a major threat The study of the physical characteristics and the dynamical evolution of object 2023 FY3, in which the Instituto de Astrofísica de Canarias (IAC) and the Complutense University of Madrid (UCM) have participated, enhances our limited knowledge about the

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
