的封面 Greg Roza: How Are Stars Born? (PDF)

The night sky seems so constant. In reality, stars are being born, burning, and dying all the time. There’s just so many of them, and they’re so far away that we barely notice without the help of sophisticated scientific tools such as the Hubble Space Telescope. In this book, budding astronomers will learn about the life cycle of a star. They’ll read how stars differ and how our sun compares to some of these stars. Incredible, colorful photographs and thought-provoking text will ignite imaginations.
