A stunning visual exploration of the power and behavior of light across the entire electromagnetic spectrum.

Light allows humans to see things around us, but we can only see a sliver of all the light in the universe, also known as the electromagnetic spectrum. Renowned science communicators Kim Arcand and Megan Watzke bring the entire spectrum to life and present the subject of light as never before. Organized along the order of the electromagnetic spectrum--from Radio waves to Gamma rays--each chapter focuses on a different type of light. From ultraviolet light, used in microscopy to image plant cells and bacteria, to X-rays, which let us peer inside the human body and view areas around black holes in deep space, Arcand and Watzke show us all the important ways light impacts us. With hundreds of stunning full-color photographs, including new images from the James Webb Space Telescope, Light is a joy to read and browse.

Take a journey through the cosmos with Light from the Void, a stunning collection of photographs from the Chandra X-Ray Observatory's two decades of operation. The book showcases rarely-seen celestial phenomena such as black holes, planetary nebulae, galaxy clusters, gravitational waves, stellar birth and death, and more. Accompanying these images of incredible natural phenomena are captions explaining how they occur. The images start close to home and move outward: beginning with images of the Chandra launch, then moving into the solar system, through the nearby universe, and finally to the most distant galaxies Chandra has observed, the book brings readers on a far-out visual voyage.

Astronomers have made remarkable discoveries about our Universe, despite their reliance on the flat projection, or 2D view, the sky has offered them. But now, drawing on the vast stores of data available from telescopes and observatories on the ground and in space, astronomers are using 3D technology to go beyond a flattened view of the cosmos. In Stars in Your Hand, Kimberly Arcand and Megan Watzke offer an illustrated guide to exploring the Universe in three dimensions, with easy-to-follow instructions for creating models of stars and constellations using a 3D printer and 3D computer imaging.

Stars in Your Hand and 3D technology make learning about space an adventure. Intrigued by the stunning images from high-powered telescopes? Using this book, you can fly virtually through a 3D spacescape and hold models of cosmic objects in your hand. Arcand and Watzke outline advances in 3D technology, describe some amazing recent discoveries in astronomy, reacquaint us with the night sky, and provide brief biographies of the telescopes, probes, and rovers that are bringing us so much data. They then offer images and instructions for printing and visualizing stars, nebulae, supernovae, galaxies, and even black holes in 3D. The 3D Universe is a marvel, and Stars in Your Hand serves as a unique and thrilling portal to discovery.

Jax Bishop wonders how he'll ever finish his report on space that he left to the last minute. Now it's school break and the big soccer game is coming up. But when he turns on his laptop, Zaria from the planet Zix appears on his screen. She's made contact with Jax so she can interview an Earthling for her special Zorketh training. They decide to collaborate, and Zaria starts - by turning Jax's room into a black hole Things get weirder when Ollie, Jax's big shaggy dog, starts to communicate with Zaria. And when Jax's best friend, Jefferson, bursts into Jax's room, things really get complicated. Can Jax keep everything under control - or is his own personal alien at risk of being discovered?

Note to Teachers, Parents, Grandparents, and Caregivers: An Alien Helped Me with My Homework is for readers ages 8-12. It has black and white comic-style sketches at the beginning of each chapter and 35 high resolution images from NASA and other organizations. All of the science information has been fact checked by a senior astrophysicist. Each chapter ends with a simple simulation that the reader can try. Important words/concepts (e.g., the categories of black holes) are italicized in the text and defined in a glossary at the end of the book. Ideas to think about and interesting additional facts are provided in star-shaped inserts in the margins.
