Our solar system lies in a suburb of a vast celestial city, a colossal community of stars, bound together by gravity; the Milky Way galaxy. Today, astronomers are piecing together the evidence which is allowing them to see our galaxy in a new and exciting way, allowing us to take the Earth on an incredible journey through space and time to see how different neighborhoods of our vast star city would appear if we could visit them close up.
