Publisher's Summary

Comet begins with a breathtaking journey through space astride a comet. Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark. 

Were the fates of the dinosaurs and the origins of humans tied to the wanderings of a comet? Are comets the building blocks from which worlds are formed? Comet is an enthralling adventure, indispensable for anyone who has ever gazed up at the heavens and wondered why. 

PLEASE NOTE: When you purchase this title, the accompanying PDF will be available in your Audible Library along with the audio.

Lots of important science and cosmic perspective

This book starts with the quaint musings of ancient Chinese record keepers on the fortune brought by different shapes of comets.

It follows our evolution in thought about comets to the present day, where we recognize them as leftovers from the formation of the solar system. We see in them the building blocks of life. We credit them for the formation of Earth's oceans. Comets are a lot more than bad omens in the sky. Except for that one time 65 million years ago!

I love how much knowledge Sagan was able to connect seemingly effortlessly to these rare visitors.

I enjoyed a lot this book

I learned so many new things from this book! It opened my appetite and I look at the Universe in a totally different way now.
It may be boring for some and amazing for others.

Great Book! Needs more MacFarlane

I really enjoy Sagan's work, even though some of it is now outdated (which he would love, by the way). But the narrator for the majority of this book doesn't seem to quite click with the material.

Beautifully Written and Very Informative

The science fiction lover in me drives me to read the occasional popular science text such as A Brief History of Time or Comet by Sagan and Druyan. This is an excellent survey of our understanding of comets for the non-specialist. It opens with a long historiography of the ancient, medieval and early modern world’s view of comets as harbingers of disaster. Then moves into the scientists who evolved our current understanding of these fascinating celestial bodies. Halley and Newton stood out most strongly to me, but they were by no means the only ones. The book winds up with explorations of the probable impact (pun intended) of comets on the development of our planet and the life upon it. If you’ve any curiosity about any of these issues, you’re likely to greatly enjoy Comet.

Enchanting!

I thoroughly enjoy reading anything that Carl Sagan writes, so saying that this book is extraordinarily good is definitely a biased opinion. however, I enjoyed one perk that I didn't expect from this audiobook. I enjoyed the narration very much. The narrator was clear, enunciated very well, and never failed to read with considerable enthusiasm. I highly recommend this book for anyone who is curious, and anyone who enjoys good narration.

I’m not sure that I can take much more .....

I’m really trying to like this book but after only four insufferable rambling chapters, it’s not looking very likely.

Airborne Sky God

The night sky filled my dreams with comets in their intimacy. Virtually sleep through time itself.

Not as great as other Sagan's books

The narration is terrible - sounds like text-to-speech most of the time, and spoils it a lot.
The book itself... I love Sagan, and have enjoyed pretty much everything else he wrote, but this one feels like there's just not enough to talk about for a whole book, so the material is spread very thinly.
Overall, so far it's the least favourite of Sagan's books for me, I am afraid.
