Twinkle, Twinkle, Nighttime Sky is the second board book in the Skytime series, based on a cozy and familiar nursery rhyme. Young readers are introduced to the vast, remarkable sky beyond our solar system.

When we look up at the stars, what we see is only a small piece of our huge universe. What else is out there in the nighttime sky? 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.
