A team of researchers from the Instituto de Astrofísica de Canarias (IAC), collaborating with other international institutions, has managed to find new galaxies in the Spiderweb protocluster. This was possible thanks to the James Webb Space Telescope, which is a project of the space agencies of the United States (NASA), Europe (ESA) and Canada (CSA). Exploring the populations of galaxies, and discovering their physical properties in large scale structures helps astronomers to understand galaxy formation and how their assembly is determined by their environment. The “ Spiderweb” protocluster
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
The Instituto de Astrofísica de Canarias (IAC) is joining the Earth Hour, a global movement that, once a year, reminds us that nature is the planet’s life support and highlights the environmental emergency that requires collective action.
