English | PDF,EPUB | 2018 | 220 Pages | ISBN : 3319977008 | 5.03 MB

​The universe contains many unusual sights and sounds, most of which are either very difficult to witness or simply go unnoticed. With the right tools, time, and location, some of the often talked about but seldom seen and heard gems in our skies can finally be observed. This book introduces readers to the rare and ephemeral happenings above our heads. It offers a crash course in astronomical history, detailing the observations, assumptions, and inventions of different cultures over time as they turned their studies to the stars. Using this as a baseline to redefine truly "rare" occurrences, Jonathan Powell then provides modern-day astronomers at all levels with pointers for what they can witness and when. From phenomena as old and far-off as a supernova witnessed a thousand years ago, and as recent and nearby as Sputnik's famous beeping, this book covers everything that one must know to see, hear, and appreciate the astronomical events happening around us.

宇宙中包含许多奇特的景象和声音，大多数情况下既难以目睹又常常被忽略。在正确工具、时间和地点的帮助下，我们可以观测到平时常被谈论但很少有人见到和听到的一些天空中的稀有现象。这本书向读者介绍了头顶上那些罕见而短暂的事件。它提供了一门天文历史速成课，详细说明了随着时间推移的不同文化对星体观察的研究、假设以及发明。以此为基础重新定义真正的“罕见”现象，乔纳森·波尔则为不同层次的现代天文学家提供了观测什么和何时观测的指导。从一千年前被观测到的一颗超新星到最近且接近地球的人造卫星发射时发出的著名鸣叫声，这本书涵盖了人们需要了解的一切，以便观测、听到并欣赏我们周围发生的天文事件。
