"How I wonder what you are ... let's explore beyond our star! Each evening, stars light up the sky and the moon appears in one of its many phases. But what else is out there in the nighttime sky? Based on the familiar nursery rhyme, Twinkle, Twinkle, Nighttime Sky introduces children to the many spectacular things in outer space ... from constellations and astronauts to galaxies and nebulas. In this book, the nighttime sky truly twinkles!"--
