Book review – Life in the Cosmos: From Biosignatures to Technosignatures

8-minute read

Are we alone in the universe? For the moment, this question remains unanswered, though there are many ways to tackle it. Just how many was something I did not appreciate until I sunk my teeth into Harvard University Press’s new flagship astronomy title Life in the Cosmos. Written by astrobiologist Manasvi Lingam and theoretical physicist Abraham “Avi” Loeb, this is a book of truly colossal proportions, clocking in at over 1000 pages. It boldly goes where few academic books have gone before by seriously and open-mindedly considering the possibility of extraterrestrial technological intelligence on par with, or far beyond humans. I found myself gravitating towards this book on account of more than just its size.

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 – 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.
