100 Things to See in the Night Sky
Dean shares his handy field guide for the best stargazing experience whether in your own back yard, camping, or travelling—including information showing you which planets, constellations, stars, and manmade objects you can see with a telescope, or just your naked eye!
Each object is presented as a separate entry, with background information on the makeup, appearance, and history of the object, along with easy-to-follow instructions on how to find it. For astronomy and space fans of all ages, this guide helps you explore the galaxy and see the stars—while keeping your feet on the ground.
Facts From Space!
From Super-Secret Spacecraft to Volcanoes in Outer Space, Extraterrestrial Facts to Blow Your Mind!
Dean's first book will take you from the Earth to the edge of the universe and back.
How did turtles, flies, meal worms, and bacteria become the first living things to go the far side of the Moon? How do you go to the bathroom in zero-gravity? Where should we look for aliens? You will see a Martian sunset, swirl in Jupiter’s Great Red Spot, skim the corona of the Sun, and fall into a black hole.
