This book is a Weekend Pocketbook on Everything You Should Know About the Milky Way, the galaxy we live inside but can never step outside to see. How do you map a galaxy when you are trapped inside it?For thousands of years, humans looked up at the bright river across the night sky and turned it into myths. Then astronomers learned to count stars, measure distances, see through dust, and slowly uncover the shape of our home.
The Milky Way is not a quiet island of stars. It is a living system. Gas collapses into new suns. Stars die and return their material to space. Explosions carve bubbles around us. The ashes of old stars become the raw ingredients for planets, oceans, bodies, and life. The monster black hole at the center is mostly quiet today, yet surrounded by signs of a violent past. What do streams of old stars reveal about smaller galaxies the Milky Way has swallowed?We also look outward to our neighborhood: the Large Magellanic Cloud, Andromeda, and the strange gravitational dance shaping our future.
What Will Happen When the Milky Way and Andromeda eventually collide? What happens to the Sun, the Solar System, and the galaxy we call home?
