An informative look at how scientific theories have changed over time concerning the solar system.

The ancient Chinese thought they were magical dragons. Scientists thought they could only float on water since they were so big. Boy, were they wrong! Even today, notions about dinosaurs are being revised as new discoveries are made. This lively book offers fascinating insight into how certain theories were formulated, and then how those theories were proved or disproved.

A hilarious nonfiction picture book from the New York Times bestselling author and creator of Awkward Yeti. Oh hey, guess what? The Sun never stops working to keep things on Earth running smoothly. (That's why it's been Employee of the Month for 4.5 billion years.) So why does the Sun get to be the center of attention? Because it's our solar system's very own star! This funny and factual picture book from Awkward Yeti creator Nick Seluk explains every part of the Sun's big job: keeping our solar system together, giving Earth day and night, keeping us warm, and more. In fact, the Sun does so much for us that we wouldn't be alive without it. That's kind of a big deal. Each spread features bite-sized text and comic-style art with sidebars sprinkled throughout. Anthropomorphized planets (and Pluto) chime in with commentary as readers learn about the Sun. For instance, Mars found someone's rover. Earth wants the Sun to do more stuff for it. And Jupiter just wants the Sun's autograph. Funny, smart, and accessible, The Sun Is Kind of a Big Deal is a must-have!

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?

Zoooooooom! We're off on an exciting space adventure in our rocket to meet all the planets of the solar system. Join in with the rhymes and spot all the smiley-faced, friendly planets, from shimmering Saturn to mighty Mars. Little ones will have a blast (and be back in time for bed!) in this striking, read-aloud, story-led picture book. It's perfect for all would-be astronauts! A special edition where the words and pictures take you on a journey far beyond the page. This audio-enabled eBook comes with a gorgeous reading by Sarah Ovens, along with music and sound effects.

Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have existed for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.
