Perceptions of meteors were diverse among the M!ori. Meteors were generally seen as omens of evil or death (Best 1955; Mackrell, 1985:21-28). A meteor may portend the death, or the rise and fall, of a 11. Blank.

A handy field guide for the best stargazing experience whether in your own back yard, camping, or travelling—including information showing you which planets, constellations, stars, and manmade objects you can see with a telescope, or just your naked eye!The night sky is full of amazing things to see—from shooting stars and constellations to planets and satellites—but it can be hard to tell what you’re seeing, or where to look for the best view. 100 Things to See in the Night Sky gives you a clear picture of what you can see on any given night, either using a small telescope, or just your naked eye. Each object is presented as a separate entry, with background information on the makeup, appearance, and history of the object, along with easy-to-follow instructions on how to find it. For astronomy and space fans of all ages, this guide helps you explore the galaxy and see the stars—while keeping your feet on the ground. It is said that astronomy is one of the few remaining fields in which amateurs can make a real contribution to science, and nowhere is this more true than in the field of meteors and meteorites.Although meteors are isolated and unpredictable, it is possible to predict when meteor showers - usually associated with old comets - are due they last a couple of days, during which many meteors can be observed in a single night. Equipment for watching, counting and even measuring meteors can range from the simplest (a chair) to sophisticated all-sky cameras.What is unique about meteors in astronomical observation is that many survive entry into the Earth\'s atmosphere and impact the ground - the only easily-analysed extraterrestrial material available to science.What is unique about Richard Norton\'s book is that it is both a field guide to observing meteors, and also a field guide to locating, preparing and analysing meteorites. In addition to giving the reader information about observing techniques for meteors, this book also provides a fully detailed account of the types of meteorites, how and where to find them, how to prepare and analyse them. It is thus the only complete book on the subject available at present. Part of the best-selling Draw 50 series this step-by-step guide to sketching and rendering astronauts, planets, asteroids, comets, spaceships, space stations, and other elements related to outer space exploration is for artists of all levels.In this new installment of Lee J. Ames\'s beloved Draw 50 series, readers will find easy-to-follow, step-by-step lessons for outer space drawing. In each lesson, six wordless steps provide everything needed to master drawing all kinds of planets, moons, comets, and meteors, as well as astronauts, rockets, spaceships, and other aspects--both natural and manmade--related to charting the cosmos.
