The Mystery Of Meteors

Brilliant comeback after 25 years for an inaugural Juniper Prize-winner.

"What are asteroids, comets, and meteors made of? What can scientists do if an asteroid is headed toward Earth? Learn how astronomers prepare for space objects hitting Earth, from tracking them to building asteroid-hunting telescopes. Budding astronomers will learn all about meteors, asteroids, and comets, including the history of asteroids hitting Earth and the differences between space rocks"--

Hurtling through the atmosphere, in a blaze of light and reverberating percussions, the arrival of a meteorite on Earth is a magical, rare, and precious sight. These characteristics have accordingly ensured a long, yet often controversial history. For all this, meteorites are cosmic messengers. They tell us about the entire history of the solar system, their story carrying us from the very earliest moments, when solid material first began to form in the solar nebula. Indeed, meteorites played a key role in the origins of Earth's oceans and the genesis of life. Meteorites additionally tell us about the origin and evolution of the asteroids, and they tell us about impacts upon the Moon as well as the volcanic history of planet Mars. Much is known about the structure and chemistry of meteorites, but for all this, they still harbor many scientific mysteries that have yet to be resolved.

"Quillan Hedgeson, a hedgehog, and Raymond Ratzburg, a rat, are students (and crime solvers) at Elm Tree Elementary school. When a famous local meteorite goes missing, Q and Ray set out to solve the case, using their wits and a series of disguises"--

Presents information about the asteroids, comets, and meteors found in the solar system, describing their physical components, orbits, and the effects of their possible collisions with the Earth and other planets.
