Just in time for the third North American total solar eclipse of the twenty-first century, this book explains how to safely observe solar eclipses, how long eclipses last, and why they result in a blackout period during the day.

This book teaches readers about what solar and lunar eclipses are, what causes them, and how often people around the Earth can witness them with their own eyes. The book is complete with labeled images when needed, simple text, and more facts. Aligned to Common Core Standards and correlated to state standards.--

"Did you know that the Sun and the Moon appear the same size in the sky? That's because the Sun is 400 times bigger than the Moon, but also 400 times farther away. It's been called "the great coincidence" but is it really just coincidence? Come take a journey through the solar system to learn secrets of the Sun and Moon, and get a front-row seat as they line up to show us the amazing eclipse miracle!"--Back cover.
