Book Description

January 24, 2012 046502193X 978-0465021932
In 1543, Nicolaus Copernicus fomented a revolution when he debunked the geocentric view of the universe, proving instead that our planet wasn’t central to the universe. Almost five hundred years later, the revolution he set in motion is nearly complete. Just as earth is not the center of things, the life on it, it appears, is not unique to the planet. Or is it?
 
The Life of Super-Earths is a breathtaking tour of current efforts to answer the age-old question: Are we alone in the universe? Astronomer Dimitar Sasselov, the founding director of Harvard University’s Origins of Life Initiative, takes us on a fast-paced hunt for habitable planets and alien life forms. He shows how the search for “super-Earths”—rocky planets like our own that orbit other stars—may provide the key to answering essential questions about the origins of life here and elsewhere. That is, if we don’t find the answers to those questions here first. As Sasselov and other astronomers have uncovered planets with mixes of elements different from our own, chemists have begun working out the heretofore unseen biochemistries that those planets could support. That knowledge is feeding directly into synthetic biology—the effort to build wholly novel forms of life—making it likely that we will first discover truly “alien” life forms in an earthly lab, rather than on a remote planet thousands of light years away.
 
Sasselov tells the gripping story of a moment of unprecedented potential—a convergence of pioneering efforts in astronomy and biology to peer into the unknown. The Life of Super-Earths offers nothing short of a transformation in our understanding of life and its place in the cosmos.

Editorial Reviews

Review

Kirkus Reviews (starred review)
“Short, cogent and stimulating”

Andrew H. Knoll, Fisher Professor of Natural History, Harvard University, and author of Life on a Young Planet
“In engaging prose, Dimitar Sasselov explains how remarkable breakthroughs in astronomy are reframing one of humankind’s oldest questions—are we alone in the universe? The Life of Super-Earths provides nutrition for the lively mind.”
 
Hans Ulrich Obrist, Co-Director of Exhibitions and Programmes, Serpentine Gallery
“Dimitar Sasselov once told me that ‘biology is the future of astronomy,’ a statement which amazed and intrigued me. In this new brilliant book he explains why his expanded notion of astronomy includes biology, and geology and chemistry, in its exciting search for new planets, new worlds, and new life. Sasselov is one of the great public intellectuals of the 21st century. He inspires artists, architects, philosophers and many others. It is urgent to read Sasselov.”
 
Nature
“In this short, sharp look at the [extrasolar planet] subset called ‘super-Earths’ — rocky or oceanic, but more massive than Earth—astronomer Dimitar Sasselov gives us the science and the speculation about life on other worlds.”

New Scientist
“[W]hat is life and how did it come about? Astrophysicist Dimitar Sasselov argues that we are on the brink of being able to answer this question, and his enthusiasm is infectious…. Only by knowing what is possible, says Sasselov in this inspirational book, can we ever understand how life got going on Earth and why it has the characteristics it has.”

Washington Post
“In his new book, Harvard astronomy professor Dimitar Sasselov lays out an optimistic case for extraterrestrial life and explains why super-Earths—rocky planets that are more massive and larger than Earth—may be better equipped to harbor the stuff of life.”

The Daily Galaxy
“[A] brilliant new study.”
 
Discover
“In this slim but absorbing introduction to the epic search for life on extrasolar planets, Sasselov explores how astronomy, geology, and biology are conspiring to give us a radical new vision of a universe in which our living Earth is ‘just another planet.’”
 
Library Journal
“As the codiscoverer of several extrasolar planets, Sasselov provides an insider’s view on planet hunting…. An interesting read.”

 

CHOICE
“Sasselov takes readers firsthand through the recent exciting discoveries of large Earth-like planets. Enough super-Earths have been discovered to enable the study of their relationship to the origins of life itself…. The well-constructed logic in this book provides plenty of support for the more interesting view that the universe is in the early phases of the evolution of carbon-rich star systems that will continue to generate life on other planets…. [A] masterfully clear statement about the possibility of life on exoplanets.”

5.0 out of 5 stars Super Earths is SUPER! January 24, 2013
Format:Hardcover
Since 1993 over 600 extra solar planets have been discovered.

While interesting what most people find truly fascinating about these newly discovered planets is the likelihood that any of them could harbor life.

It's with this real question in mind that Harvard professor Dimitar Sasselov examines what we know about life on Earth and what these newly discovered planets tell us about its likelihood elsewhere.

In short Sasselov says:

1) Far from being less hosbitable to life Super Earths are more likely to harbor it than our planet. Why this is so amazingly has to do with another interesting disclosure by Sasselov.

2) Life on Earth has a lot to with the fact that Earth has plate tectonics. Plate tectonics is the process by which continents slowly move around Earth and in so doing reshape the way the Earth looks and suffle environments to better give life a chance to arise. According to Sasselov Super Earths have better plate tectonics because they are more likely to have it than planets that are small as ours is.

3) Most importantly, when he crunches the numbers Sasselov's estimate of the likelihood of planets with life in our galaxy is somewhere in the neighborhood of 100 million.

As mentioned at the outset the search for other planets cannot help but be a search for other life. Thanks to Professor Sasselov's excellent book, readers can have a SUPER understanding of recent developments in this exciting field.

In many respects this book is excellent. It has a lot of interesting information about the discovery and composition of exoplanets. The discovery techniques are gone into in commendable detail, especially the transit method. There is also a fair bit of historical background as well. The composition relies more on computer models but the breadth of possible planets (sort of like a planetary "main sequence") is also gone into in some detail. The astronomy end of the book is great.

The biology part is a very different matter. Things start off well enough as the details of the origins of terrestrial life are reviewed. Then the author makes the plausible enough claim that a certain amount of geological activity is necessary for the development of life and earth's is just barely adequate. Super-earths, he asserts, with their greater geological activity would be more hospitable to the development of life.

By this point we have arrived at the last chapter. The book has built up to and has been pointing to the climax promised in the the book's title, "The Life of Super-Earths". I was expecting the author to tie up the biology and astronomy and show how life on super-earths would differ from life on earth. Naturally this would be somewhat speculative but that doesn't matter.

What we receive instead is a rather lame chapter on synthetic biology. Super-earths disappear from the narrative and we get a description of what biologists are hoping to do in the laboratory. All in all, I felt cheated. The promised punch line never came.

The book can be recommended nonetheless as a relative recent recapitulation of events surrounding exoplanets, both discovery and theory.

The Kindle edition was quite serviceable with a few flaws. There was an amusing glitch where exponents were linked to chapter notes. The print index was printed without the page numbers and was unlinked making it completely useless except as suggestions of terms to search for. Finally, the book was organized into two parts of six chapters each but only the parts are marked on the progress bar. Sparse progress bars are a particular annoyance as it doesn't give the reader enough indication about how much further he has to read before reaching a convenient stopping point.

Amazing and quick read. Really insightful about physical, as well as chemical, requirements for life elsewhere in the cosmos. Easy enough for a beginner to pick up, but original enough to interest space fanatics, too
