For Pluto, summer has always started with a trip to the planetarium. It’s the launch to her favorite season, which also includes visits to the boardwalk arcade, working in her mom’s pizzeria, and her best friend Meredith’s birthday party. But this summer, none of that feels possible. A month before the end of the school year, Pluto’s frightened mom broke down Pluto’s bedroom door. What came next were doctor’s appointments, a diagnosis of depression, and a big black hole that still sits on Pluto’s chest, making it too hard to do anything. Pluto can’t explain to her mom why she can’t do the things she used to love. And it isn’t until Pluto’s dad threatens to make her move with him to the city—where he believes his money, in particular, could help—that Pluto becomes desperate enough to do whatever it takes to be the old Pluto again. She develops a plan and a checklist: If she takes her medication, if she goes to the planetarium with her mom for her birthday, if she successfully finishes her summer school work with her tutor, if she goes to Meredith’s birthday party . . . if she does all the things that “normal” Pluto would do, she can stay with her mom in Jersey. But it takes a new therapist, a new tutor, and a new (and cute) friend with a checklist and plan of her own for Pluto to learn that there is no old and new Pluto. There’s just her.

The solar system most of us grew up with included nine planets, with Mercury closest to the sun and Pluto at the outer edge. Then, in 2005, astronomer Mike Brown made the discovery of a lifetime: a tenth planet, Eris, slightly bigger than Pluto. But instead of adding one more planet to our solar system, Brown’s find ignited a firestorm of controversy that culminated in the demotion of Pluto from real planet to the newly coined category of “dwarf” planet. Suddenly Brown was receiving hate mail from schoolchildren and being bombarded by TV reporters—all because of the discovery he had spent years searching for and a lifetime dreaming about. A heartfelt and personal journey filled with both humor and drama, How I Killed Pluto and Why It Had It Coming is the book for anyone, young or old, who has ever imagined exploring the universe—and who among us hasn’t?

Presents an introduction to the Solar System and the physical features of the eight planets that revolve around the Sun, in a text that includes learning activities.

Pluto has been subject to controversy since its discovery in 1930, and questions over its status linger. Is it a planet? This book provides the historical, philosophical, and astronomical background that allows us to decide for ourselves whether Pluto is indeed a planet.

A classic introduction to the story of Earth's origin and evolution—revised and expanded for the twenty-first century Since its first publication more than twenty-five years ago, How to Build a Habitable Planet has established a legendary reputation as an accessible yet scientifically impeccable introduction to the origin and evolution of Earth, from the Big Bang through the rise of human civilization. This classic account of how our habitable planet was assembled from the stuff of stars introduced readers to planetary, Earth, and climate science by way of a fascinating narrative. Now this great book has been made even better. Harvard geochemist Charles Langmuir has worked closely with the original author, Wally Broecker, one of the world's leading Earth scientists, to revise and expand the book for a new generation of readers for whom active planetary stewardship is becoming imperative. Interweaving physics, astronomy, chemistry, geology, and biology, this sweeping account tells Earth’s complete story, from the synthesis of chemical elements in stars, to the formation of the Solar System, to the evolution of a habitable climate on Earth, to the origin of life and humankind. The book also addresses the search for other habitable worlds in the Milky Way and contemplates whether Earth will remain habitable as our influence on global climate grows. It concludes by considering the ways in which humankind can sustain Earth’s habitability and perhaps even participate in further planetary evolution. Like no other book, How to Build a Habitable Planet provides an understanding of Earth in its broadest context, as well as a greater appreciation of its possibly rare ability to sustain life over geologic time.

Do you wonder if humans are the only beings who wonder if they are alone in the universe? Our sun is a star. In the night sky are all kinds of stars, and orbiting those stars are planets like the ones in our own solar system. Could those planets have life like we do on Earth? Planet Earth is not too big, not too small, not too hot, and not too cold. It’s just right. Our very own Goldilocks planet . . . . Follow a young girl as she explores these questions in this gorgeous book about the wondrous search for another Goldilocks planet.

The Latest Scientific Discoveries Point to an Intentional Creator Most of us remember the basics from science classes about how Earth came to be the only known planet that sustains complex life. But what most people don't know is that the more thoroughly researchers investigate the history of our planet, the more astonishing the story of our existence becomes. The number and complexity of the astronomical, geological, chemical, and biological features recognized as essential to human existence have expanded explosively within the past decade. An understanding of what is required to make possible a large human population and advanced civilizations has raised profound questions about life, our purpose, and our destiny. Are we really just the result of innumerable coincidences? Or is there a more reasonable explanation? This fascinating book helps nonscientists understand the countless miracles that undergird the exquisitely fine-tuned planet we call home--as if Someone had us in mind all along.
