An international study led by Almudena Prieto, a researcher at the Instituto de Astrofísica de Canarias (IAC) has found places where new stars are forming, as faint star clusters, around the centre of an evolved galaxy. This is the first time that young populations of stars have been picked out and dated in this type of galaxies dominated by very old stars, which can be called “rejuvenated old galaxies”. The research has combined observations from various telescopes, both ground based and space based, and has used innovative techniques of data analysis. The results are published in the
La Fundación CajaCanarias organiza la octava edición de su Foro Enciende el Cosmos, que este año volverá a contar con la participación de destacados científicos e investigadores de reconocido nivel nacional e internacional. Esta iniciativa de carácter divulgativo pretende expandir, desde la exploración científica, la comprensión del Universo en su conjunto, relacionando el pasado con el presente y con una clara búsqueda de respuestas de cara al futuro. El programa se divide en tres sesiones, a celebrar los días 13 de febrero, 20 de marzo y 10 de abril, en el Espacio Cultural CajaCanarias de
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
