What Is the Milky Way?

The Milky Way is just one of billions of galaxies in the universe. Yet by exploring the galaxy we call home, we have been able to uncover some of the universe’s many unknowns. This illuminating volume carefully breaks down the features of the Milky Way galaxy. It explains such characteristics as size, shape, and age; examines planets, stars, and star clusters; and delves into such concepts as black holes and dark matter. Important terms are explained, and, throughout the text, readers are invited to think critically about pertinent questions and concepts.
