The Andromeda Galaxy, our nearest neighbouring spiral galaxy. Our galaxy will collide
The Andromeda Galaxy, our nearest neighbouring spiral galaxy. Our galaxy will collide with the Andromeda galaxy in 3-5 billion years. The Milky Way contains around three hundred billion stars, and the Andromeda galaxy is over twice as massive with a trillion stars, but the space between stars is so immense that any kind of direct collision is near impossible.
