David Levy’s Guide to Observing Meteor Showers（ISBN=） 英文原版

　　Meteors occur when a meteoroid, a speck of dust in space,
enters the Earth’s atmosphere. The heat generated when this happens
causes the surrounding air to glow, resulting in ‘shooting stars’.
During the most spectacular meteor storms larger particles give
rise to fireballs and firework-like displays! Meteors are a
delightful observing field – they do not require a telescope, and
they can be seen on any clear night of the year, even in bright
twilight. It was the sight of a single meteor that inspired David
Levy to go into astronomy, and in this book he encourages readers
to go outside and witness these wonderful events for themselves.
This book is a step-by-step guide to observing meteors and meteor
showers. Any necessary science is explained simply and in clearly
understandable terms. This is a perfect introduction to observing
meteors, and is ideal for both seasoned and budding
astronomers.
