Book review – Alien Oceans: The Search for Life in the Depths of Space

8-minute read

This is the second of a two-part dive into the story of oceans on Earth and elsewhere, following my review of Ocean Worlds. That book gave a deep history of how our oceans shaped Earth and life on it and briefly dipped its toes into the topic of oceans beyond Earth. Alien Oceans is the logical follow-up. How did we figure out that there are oceans elsewhere? And would such worlds be hospitable to life? Those are the two big questions at the heart of this book. If there is one person fit to answer them, it is Kevin Peter Hand, a scientist at NASA’s Jet Propulsion Laboratory and their deputy chief for solar system exploration.

Book review – Terrestrial Impact Structures: The TanDEM-X Atlas (2-Volume Set)

7-minute read

When Google Earth first launched in 2001, I, like many others, found myself poring over satellite imagery. Identifying familiar and unfamiliar landmarks always brought a certain thrill, and spotting craters was part of that. But to properly map impact structures, you need a better dataset. The stunningly produced Terrestrial Impact Structures is a large-format atlas that maps all currently accepted ones, plus some likely candidates, and makes for an instant must-have reference work for any geology or astronomy library.

Book review – End Times: A Brief Guide to the End of the World

6-minute read

If the end of the world is something that keeps you up at night you might want to skip this book. Some might snigger at the “rogue robots” in the book’s subtitle, but End Times is a serious look at so-called existential risks. Former foreign correspondent, reporter, and editor with TIME magazine Bryan Walsh takes an unflinching look at the various disasters that could wipe out humanity, the people whose jobs it is to seriously think through catastrophic threats, and how, if at all, we can prepare ourselves.

Book review – Fire in the Sky: Cosmic Collisions, Killer Asteroids, and the Race to Defend Earth

6-minute read

Can you have too many books on the same topic? Not four months after the publication of Cosmic Impact in February 2019, which I reviewed earlier this year, Scribner books published Fire in the Sky in June. The former book was written by astrophysicist Andrew May, while Gordon L. Dillow is a newspaper reporter and war correspondent, coming at the subject from a different angle. Despite touching on many of the same events and topics, he provides a wealth of new information in what is a thoroughly researched work of popular science. But first, let’s go to Arizona and turn back our clocks some 50,000 years.

Book review – The Story of the Earth in 25 Rocks: Tales of Important Geological Puzzles and the People Who Solved Them

Judging by the title of this book, you might expect it to talk of 25 remarkable kinds of rocks and minerals. But in the preface, geologist and palaeontologist Donald R. Prothero makes clear that his book looks as much at famous outcrops and geological phenomena. Bringing together 25 readable and short chapters, he gives a wide-ranging tour through the history of geology, celebrating the many researchers who contributed to this discipline.

Book review – Catching Stardust: Comets, Asteroids and the Birth of the Solar System

Asteroids and comets have a bad reputation. Looking back over the books I have reviewed, they usually come up in the context of impact and destruction. But there are other important reasons to study them and geologist and cosmochemist Natalie Starkey here steps up as their enthusiastic spokeswoman. Whether as frozen time capsules, possible vehicles dispersing the basic chemicals required for life, or even future mining quarries, Catching Stardust champions the importance of scientific research on these celestial objects.

Book review – Cosmic Impact: Understanding the Threat to Earth from Asteroids and Comets

The idea of an asteroid or comet impacting with planet Earth and causing a catastrophe for mankind has long been given a cold shoulder in scientific circles. But with the notion that the dinosaurs met their fate at the hand of a rather large space rock it does not seem so outlandish anymore. NASA has started monitoring near-earth objects, but is there really something we could do if one was heading our way? Astrophysicist and science writer Andrew May provides a delightful little primer on these questions with Cosmic Impact, injecting this oft-hyped topic with a healthy dose of realism.

Book review – Four Revolutions in the Earth Sciences: From Heresy to Truth

Try as we might, science is very much the work of human beings with all their foibles. As such, scientific advances aren’t always straightforward and can run into opposition within scientific circles when new ideas run counter to currently established ones. In Four Revolutions in the Earth Sciences, American geologist James Lawrence Powell demonstrates this by taking the reader through the history of four ideas in the earth sciences that initially weren’t accepted. This was a book I very much wanted to read.

Book review – Cataclysms: A New Geology for the Twenty-First Century

Was the asteroid impact that caused the extinction of the dinosaurs a one-off? Or are other mass extinctions in earth’s deep history perhaps also linked to impacts of extraterrestrial bodies? Many scientists are reluctant to accept this idea. In Cataclysms, Rampino argues that it is high time to cast off the spirit of Lyell that continues to haunt geological thinking and embrace a new era of catastrophism.

Book review – The Ends of the World: Volcanic Apocalypses, Lethal Oceans and Our Quest to Understand Earth’s Past Mass Extinctions

Aaaah… the Apocalypse. Who doesn’t love Hollywood’s favourite movie trope? The spectacle, the drama, and the foreboding knowledge that – oh, spoilers – everyone dies at the end. There has been no shortage of good eschatological writing in recent years. Some books to come to mind are Erwin’s imaginatively titled Extinction, Wignall’s recent The Worst of Times, or Alvarez’s T. rex and the Crater of Doom – those pesky dinosaurs remain a popular subject. Do we really need another popular science book about mass extinctions? Given the continued developments in our understanding, and given that you get not one, not two, but all five for the price of one, I’d say yes. As far as I can tell the last comparable book was Hallam & Wignall’s 1997 Mass Extinctions and their Aftermath, published by Oxford University Press, which was a more academic treatise. So, get your bucket of popcorn ready and roll on the Apocalypse!
