UK’s Alien Worlds is still one of my favourite documentaries. Speculation based on science in general is something that I’ve always found fascinating. So It’s no surprise that Imagined Life jumped high on the list of my priorities the moment it was released.

Just like the aforementioned programme, this book is a greatly entertaining and informative tour around the universe in search of life. The book starts off with solid base in physics, chemistry, and biology laws to explain the more outlandis

Kind of disappointed in this one, but that's more on me than the authors. Both are professors of astronomy and physics, not xenobiologists - but still, where are the aliens?

The book focuses on the types of potentially habitable planets out there (a more narrow focus than their earlier, better book Exoplanets: Diamond Worlds, Super Earths, Pulsar Planets, and the New Search for Life beyond Our Solar System), and then how life could potentially evolve there and what type of technology it might de

Off to a weak start (for me). The science is at (pretty much) YA-level, and there's a lot of repetition between topics (water world, Europa analog, etc). On the plus side, lots of good info if you are at YA level on planetary/exoplanet science. And the (purely decorative) illustrations are nicely done. I haven't quite given up.... (yet).

Well, I did give up. DNF, not recommended.

Fascinating predictions for what might be discovered and how life might take shape on exoplanets, particularly the Trappist system 40 light years away.
Kasey Haught
This one was a bit disappointing. The authors approach the subject rather lightly, and it's clear this is an introductory book on astrobiology for less advanced readers, which is one thing, but doesn't excuse a few pervasive misrepresentations of developmental processes when they do go on to imagine life.

In particular, they repeatedly describe hypothetical worlds developing advanced intelligent organisms under ecological conditions that would likely preclude the production of sufficient oxygen

Repetitive

It is hard to make et life boring, and this book isn't quite that bad. But there's only about half a book of content, which means lots of filler and repetition.

Imagined Life by James Trefil & Michael Summers has the extended title of A Speculative Scientific Journey Among the Exoplanets in Search of Intelligent Aliens, Ice Creatures and Supergravity Animals

Let me start with my interest in buying this book. I’m a big science fiction fan but also a fan of the science community, in particular astronomy. I love hearing the discoveries of those who are doing the wonderful work of discovering extrasolar planets, those planets around stars other than our own

Some of the science went over my head but ultimately a really interesting book. It's really great for people who are interested in book space and biology since the authors explain a lot of Earth's biology and evolution to prediction how life might form on different exoplanets ...more

This is a little wacky, but entertaining and thought-provoking.

I have a poster in my house from a science fiction magazine in the 1940s, depicting an imaginary scene on Pluto. The text reads, “This world of cold and eternal twilight would most likely be inhabited by winged bat-people with heavy protecting fur.”

Of course, the science in this book is updated, and Trefil and Summers talk like scientists, not poster-writers, but some passages in the book sound just a little bit like that poster. The

An amazing book that makes you look at the possible planets and life that could exist on them. I had a lot of fun reading it. It is definitely able to ground your thoughts on what is likely and what isn't. If you are writing a sci-fy novel, this book will help with the science part and the rest you can distort at your leisure. I had a fantastic time, and I'm sure you will too! ...more

The authors use this text to expand upon the possibilities of life on the exoplanets they study. Their focus is on forms of life already known to exist: carbon-based and dependent on liquid water. They also speculate about several other possibilities, giving us a run through on the basic types of exo-planets discovered in recent years and some local moons and planets of interest, as well as rogue planets ejected from their natal systems to roam the universe without a star to call their own.

This book is one part classical sciences, one part astronomy and one part thought exercise. The authors tightly lay out the physical laws of the universe, and how these laws can enable life in the distant cosmos. Readers are taken through ice worlds, water planets, tidally locked planets and rogue planets and the likelihood of life among them. Imagined Life is written for the lay reader, and serves as thought fuel for amateur astronomers. The text begins and ends with the difficulties in definin ...more

free audiobook on library website. I originally just wanted a distraction from moments when my brain wont shut up an don't feel like doing anything. iv had two "potential astronauts" in my life & have also learned information, from various sources. only listened to 6ch, may come back some other time to finish this book. the preface makes it sound just slightly interesting/new information, but don't skim! continue the book. it was done slightly different but some has been done before, though done ...more

I almost chose the shelf for fantasy :) But this is a well-informed, scientifically based speculation on what life might be like on the several different kind of planets if ever we can get out there, such as one that always has one face turned towards its star (e.g. Mercury), a frozen planet (e.g. Neptune) and even a planet wandering without a sun. Fun to speculate, hard to think that the latter might have life intelligent like ours (or more rather since we seem to want to destroy ourselves with ...more

Fun read, though a bit too fantastic for my taste. I liked how the author discussed a lot of the foundation theories of science to base the hypothesis of what life would look like on other types of worlds, but it seemed like they made large jumps. in advancement, that would require sooo many other elements to fall into place. I did particularly enjoy the points in the book that described how different types of telescopes and spectrometers work in identifying how planets are composed. I also like ...more

I wanted to rate it more highly but wish that the "weight" of each chapter were more consistent. I enjoyed the opening chapters laying the groundwork and science for the rest of the book. And then each imagined scenario weakened as things got more speculative -- which is totally understandable but which left me with a deflated feeling as I plowed through the last third of the book.

Overall a fun a stimulating read, but you can't get my gears turning like that and then slow down! :)

This brief survey of what we know about the development of life and how life might develop on the types of exoplanets we know about was very accessibly written and extremely interesting. I wish the authors had gone into a bit more detail on some topics, but the nature of a survey is that it’s impossible to do so I suppose! All in all a great introduction to a more scientific conversation about what kind of life might be out there, how it would work, and how we might look for it.

Pretty weak as speculation goes.
There is nothing in it one cannot find surfing the internet.
I would recommend this book for highschoolers, as the science in it is very thin and the imagined life is almost nonexistent.
All in all, it is nothing more than a descriptive list of a few interesting exoplanets.
Not worth the time nor the money.

This may be though provoking for somebody who is just getting started in arm-chair astrobiology or alien life but it's nothing groundbreaking. It doesn't really go into detail of how life would emerge or evolve beyond "one it's there here is a core tech it would need to cope with it's planet". The content felt light and more of a light read at bedtime than something to really get you thinking. ...more

Very easy to read speculations about what life and technology would look like and how they would develop on other planets and exoplanets. It is a little repetitive in that the authors do refer back to previous chapters quite often, but overall is a good book for the laymen.

Very thought provoking and hacked by very scientific and sound theories. Nothing seemed too far out, and if it did it was easily made understandable by the authors. It really shows you the how important it is for more of a focus on Astrobiology

Very enjoyable. If I was writing SF this would be in my reference section in order to create plausible life forms on other worlds. Short but very informative without being too difficult for the lay person

Very interesting and thorough explanations of what other potential life forms there could be and how they would evolve in different conditions ( like water world, ice planets etc). Notably, we are but a small speck in the universe.

This was cool, a little repetitive at times but I was able to tolerate it for sure.
I’m new to astronomy, so this was certainly an entry point for me.

I can totally see why more advanced readers wouldn’t enjoy this though.
