Rosetta isn’t the first probe that’s been sent to study comets, but it’s the most successful as the first spacecraft to closely observe a comet as it approaches the sun. For 10 years, Rosetta moved around the solar system, just so it could finally meet up with the right comet and release a lander to further study it. Readers learn about Rosetta’s incredible journey from just an idea to a fascinating robot with solar-charging batteries and other special features. From full-color diagrams of Rosetta to informative sidebars about the probe’s findings, readers are sure to enjoy this book’s STEM content.

This title explores how cells have formed the dazzling array of life that we see around us. No one knows how many millions of different species there may be on our planet, and new ones are discovered every year. Scientists classify living things into different groups in order to help make sense of this diversity of life. This book looks at the way classification has changed over time, including a recent suggestion to classify living things into three domains rather than six kingdoms.
