Researchers at the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), publish today in the journal Astronomy & Astrophysics the first results of a detailed study of nearly a thousand blue supergiants in the Milky Way. This is the biggest sample of stars of this type which has been studied until now. The study has used over 15 years of high quality observations taken mainly with the NOT and Mercator telescopes at the Roque de los Muchachos Observatory in La Palma. The analysis of these data will allow researchers to improve their knowledge of the evolution ofAdvertised on

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-onAdvertised on
