--New York Times Book Review "Will leave readers who aren't rocket scientists slack-jawed"
--New York Times "Billings performs a brilliant sleight of hand...the ending is a poignant reminder that humankind may yet find a way to the stars, but people -- the ones we know, the ones we love, the ones we lose -- are our entire history and our full universe."
--The Washington Post "The search for Earth-like worlds orbiting distant stars is just a step in the age-old quest to learn whether or not we are alone in the universe. In his compelling, wide-ranging survey, Billings steps back to look at this broader picture, largely through richly textured portraits of some of the giants of the field...[an] extraordinary tale of scientific discovery."
--Scientific American "Fascinating... A great outline of the subject, bringing what's often treated as science fiction down to Earth where it can be understood."
--Kirkus Reviews "Exoplanet detection is space science's hottest field, one which science writer Billings surveys here with exceptional clarity while peering over the shoulders of the planet hunters' leading pioneers...a fascinating and informative read for both casual and serious astronomy buffs."
--Booklist "Readers will find [Five Billion Years of Solitude] incredibly engaging...Billings has created a book that is not only entertaining, but educational as well."
- Universe Today "Billings communicates scientific and technical detail fluently, and there is much here to please any geek who does not already know how, say, it is possible to see a distant planet next to a star that outshines it as an exploding nuclear bomb does an unlit match."
--The Guardian "Astrobiology, the study of alien life, has been a dream--until now. Suddenly the detection of life on other planets no longer seems quite so peculiar. Lee Billings explains how the impossible dream became possible after all."
