Deep Sky Objects pdf epub mobi txt 電子書 下載 2024
Veteran comet hunter and eloquent popular astronomy writer David H. Levy takes amateur sky-watchers on a fascinating journey into deep space in this enthusiastic and informative survey of the many far distant yet observable objects in the night sky. Light years beyond our solar system, deep sky objects include such intriguing phenomena as double and triple stars, nebulae, galaxies, and quasars. Designed to be accessible for even beginners, Levy's clear, elegant descriptions will guide astronomy buffs in any hemisphere and locale (light-polluted cities as well as dark countryside) to the wonders of our enormous universe. As the discoverer or co-discoverer of twenty-one comets, including the famous Shoemaker-Levy 9 that crashed into Jupiter in 1994, Levy has devoted many decades of experience to observing the night sky. Over the years, he has located over 300 deep sky objects, of which more than 100 'best and brightest' are featured in this book. Levy offers a physical description and a discussion of each object's history and beauty, as well as a star atlas to aid in finding the objects. Proceeding from objects closest to our solar system to those farthest away, Levy gives readers an awe-inspiring glimpse into the structure of the cosmos. Complete with both colour and black and white photos, plus many helpful illustrations, "Deep Sky Objects" is the ideal guide to the wonders of the universe for both experienced and novice star gazers.
