Guide to our Galaxy
Take a virtual journey through the Milky Way! This virtual journey shows the different components that make up our home galaxy, the Milky Way, which contains about a hundred billion stars. It starts at the black hole at the centre of the Milky Way and with the stars that orbit around it, before zooming out through the central Galactic Bulge, which hosts about ten billion stars. The journey continues through a younger population of stars in the stellar disc, home to most of the Milky Way’s stars, and which is embedded in a slightly larger gaseous disc.
