Move to another planet? Sounds interesting! In our imaginary spaceship, let's check out the planets in our solar system. Mercury is closest, but it has no air, and it's either sizzling hot or bitterly cold. The atmosphere on Venus is poisonous; plus, human beings would cook there. Mars might work, but you'd always have to be in a protective shelter. And if you got to the outer planets, you couldn't even land as they are mostly made of gas! Our home planet is looking good. Why is Earth so comfortable for plants, animals, and people? As Robert E. Wells explains, it's because of our just-right position form the sun, marvelous atmosphere, and abundant water. Our planet is very special and perfect for us, and that's why we must do all we can to keep Earth healthy.

"Tender and illuminating. A beautiful debut." --Rebecca Stead, Newbery Medal-winning author of When You Reach Me A heartrending and hopeful story about a nonverbal girl and her passion for space exploration, for fans of See You in the Cosmos, Mockingbird, and The Thing About Jellyfish. Twelve-year-old Nova is eagerly awaiting the launch of the space shuttle Challenger--it's the first time a teacher is going into space, and kids across America will watch the event on live TV in their classrooms. Nova and her big sister, Bridget, share a love of astronomy and the space program. They planned to watch the launch together. But Bridget has disappeared, and Nova is in a new foster home. While foster families and teachers dismiss Nova as severely autistic and nonverbal, Bridget understands how intelligent and special Nova is, and all that she can't express. As the liftoff draws closer, Nova's new foster family and teachers begin to see her potential, and for the first time, she is making friends without Bridget. But every day, she's counting down to the launch, and to the moment when she'll see Bridget again. Because as Bridget said, "No matter what, I'll be there. I promise."

Why Earth’s life-friendly climate makes it exceptional—and what that means for the likelihood of finding intelligent extraterrestrial life We have long fantasized about finding life on planets other than our own. Yet even as we become aware of the vast expanses beyond our solar system, it remains clear that Earth is exceptional. The question is: why? In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is what makes it uniquely able to support life, and it is nothing short of luck that made such conditions possible. The four billion year-stretch of good weather that our planet has experienced is statistically so unlikely that chances are slim that we will ever encounter intelligent extraterrestrial others. Citing the factors that typically control a planet’s average temperature—including the size of its moon, as well as the rate of the Universe’s expansion—Waltham challenges the prevailing scientific consensus that Earth-like planets have natural stabilizing mechanisms that allow life to flourish. A lively exploration of the stars above and the ground beneath our feet, Lucky Planet seamlessly weaves the story of Earth and the worlds orbiting other stars to give us a new perspective of the surprising role chance plays in our place in the universe.
