Everyday, the sun sets and the sky grows dark. Twinkling stars start to shine, and we watch the moon as it changes phases throughout the month. But the sky we see each night is only a small piece of our huge universe. What else is out there in the nighttime sky? Twinkle, Twinkle, Nighttime Sky is the second board book in the Skytime series, following Twinkle, Twinkle, Daytime Star. Based on the familiar nursery rhyme, the Skytime series first introduces kids to the bright star that lights our daytime sky, and now explores the universe beyond our solar system! Readers learn about constellations, how the moon affects the tides, astronauts and the moon landing, our Milky Way galaxy and the billions more galaxies out in space, phenomena such as comets and nebulas, and so much more. Twinkle, Twinkle, Nighttime Sky is a must-have for children who love marveling at the stars and learning about astronauts and planets. With breathtaking illustrations of space and fascinating facts, this book puts our one-of-a-kind planet in perspective!
