From Publishers Weekly

Steel estimates that a massive asteroid capable of wiping out a fourth of humanity can be expected to collide with Earth roughly once every 100,000 years. In the immediate offing, he maintains, we can expect smaller cataclysmic impacts similar to the Tunguska explosion of 1908, which devastated a vast expanse of Siberian forest (he believes that an asteroid blew up in the atmosphere above the Tunguska River). Written in clear prose for the layperson, this gripping report advocates the creation of an international search program to detect, intercept and divert Earth-menacing asteroids and comets. Steel, an English astronomer based in Australia, served on two NASA committees investigating potential impact hazards. He endorses the theory that asteroid collisions caused not only the dinosaurs' extinction but also many other mass extinctions during the past few hundred million years. Steel's hypothesis that the Taurid meteoroid stream poses the major risk to Earth is bound to be controversial, as is his speculation that the Taurid Complex of meteor showers produced huge storms and Tunguska-type explosions on Earth around 4500 years ago?and that Stonehenge was built to observe and predict these cataclysms.

From Library Journal

Here is a recipe for a fascinating literary dish: Take the history of comet impacts on Earth. Add the latest scientific findings from astronomers and geologists. Stir in related theories about the origin of Stonehenge and the extinction of dinosaurs. Mix well with statistics on the chances of future terrestrial collision and the evidence from the recent comet explosion on Jupiter. Spice liberally with science fiction-like images of catastrophic scenarios. Bring to a simmer with government plans for detection and interception of an approaching "death star." Serve immediately to horrified millions. The result is guaranteed to satisfy the appetite of interested lay readers for all the facts, scientific beliefs, and uncertainties about the danger of comets and asteroids crashing into Earth. The head chef is author Steel, an Australian astronomer and world authority on comet hazards. The appetizer is a foreword by Arthur C. Clarke. Gourmet reading!?Valerie Vaughan, Western Mass.

4.0 out of 5 stars Death from Space! - sometime., October 15, 1998

By A Customer

This review is from: Rogue Asteroids and Doomsday Comets: The Search for the Million Megaton Menace That Threatens Life on Earth (Paperback)

Three events in the past decade have caused a great deal of interest in objects around us in space. Giotto's encounter with Halleys Comet, Hubble Space Telescope pictures of the Shoemaker/Levy comet crashing onto Jupiter and lastly the naked eye sightings of the Hale/Bopp Comet we have enjoyed earlier in the year. Originally from Somerset, Duncan Steel now works at the Anglo-Australian Observatory and his book provides a very readable account of the nature and movements of these very varied objects.

Ever since the first pictures of other planets and in particular their moons arrived, studies have been made of their cratering records. Pictures from space have also been the main method of detecting craters but this time down on earth where plate tectonics, erosion, sediments or vegetation tend to erase them.

Astronomy and Geology linked up when cosmic impact events were suggested as possible cause or trigger for some of the major extinctions we find in the fossil record. The effects of both solar and cosmic cycles on all aspects of life on the planet are now widely studied.

Mr. Steel gives an account of a very bright meteor seen by many people in 1993 in New South Wales. When asked for an estimate of how soon it would before another such sighting to occur the answer was given in years. One week later, however, an object estimated to be 2-3 meters in size and traveling at 30Km/Sec exploded 18Km overhead with the amount of energy produced by a Hiroshima Bomb. Events such as these and the trail of impacts left on Jupiter show that objects in space are certainly not solitary. Lines of craters have been found on other moons in the system. Comet Hale/Bopp provided a spectacular sight a few months ago but for now the interest is in the debris and dust they and asteroids can leave behind often in highly eccentric trails across our orbit. Gravitational forces and solar wind affect the objects and the trails have a structure and it is the "busy" parts of the belt which give the peaks to meteor showers as we pass. The widely varying time scales which have been linked with extinctions and other cycles are the result of earth and solar system moving round the galaxy.

The possible effects of a large impact, global warming, ice ages, large fire storms or basalt floods have all been discussed elsewhere but the book considers several other theories. A large object landing in the ocean could cause a truly instant catastrophe.

This is the tsunami wave which can be caused by earthquakes or large undersea slope collapse. Islands in the middle of the Pacific can feel the effects of activity right across the ocean. The sloping continental shelves amplify the height of the waves and in low lying areas they can reach well in land. Observations of the cratering pattern on Mercury led to one theory where the shock waves from a large impact travel round the globe and fracture the crust on the opposite side. Reconstruction of the continents at the times of suggested impact events seems to make it possible to link basalt floods such as the Deccan traps with their "opposite" partner.

The remainder of the book deals with the problems involved first in detecting objects which may be a threat to the earth and also discusses what or how anything could be done about it. The pictures of S/L 9 described as a "string of pearls" as it approached Jupiter show just how much of a problem this could prove. For a book found

on the astronomy shelves in the library this one provided a very interesting read and shows that we on earth are not alone in space.

4.0 out of 5 stars Ignore speculation and you have a good book.., March 11, 2002

By	Jerald R Lovell (Clinton Township, Michigan United States) - See all my reviews (REAL NAME)

This review is from: Rogue Asteroids and Doomsday Comets: The Search for the Million Megaton Menace That Threatens Life on Earth (Paperback)

I liked the book, but do not rate it as highly as "Rain of Iron and Ice" by John S. Lewis and "Impact" by Gerrit L Verschuur. However, it is much better than "Fire on Earth" by John and Mary Gribben.
My chief reservation about Steel's work is that he seems easily drawn to flights of whimsy such as Clube's and Napier's contentions regarding Beta Taurid cometary impacts that have affected history on a mammoth scale. While these are captivating proposals, perhaps, there isn't enough hard scientific evidence for them clutter up what was otherwise a hitherto fine scientific presentation of a real problem by Steel. Up to the author's dalliance into the speculative, the book is a good read about a serious, overlooked, preventable threat. His admonitions should be taken seriously.

2.0 out of 5 stars Craters, December 18, 2000

By	Holy Olio "holy_olio" (Grand Rapids, MI USA) - See all my reviews

This review is from: Rogue Asteroids and Doomsday Comets: The Search for the Million Megaton Menace That Threatens Life on Earth (Paperback)

Duncan Steel is one of the best known advocates for a near Earth observation system, and he and others like him should be listened to. Unfortunately the book is not too great. It didn't hold my attention, partly because of the intrusion of some of his opinions. If nothing else is available on the topic, this could be an okay choice. See instead "Rain of Iron and Ice" by John S. Lewis
