This is the paperback edition of Ringmakers of Saturn, commissioned for the 25th anniversary of the release of the original hardback.From 45 plates of photographs taken during the Voyager 1 flight to Saturn in 1980, the reader of this remarkable book sees that one of the photographs shows that the Aring is incomplete. The author sets out to explain this phenomenon in an understandable form.The famous Cassini and Enke gaps also fit into the author s explanation. The microphotography employed by the author answers many of the questions about Saturn asked since Galileo. The author further shows a relation to the welldefined crater on the earth s moon called Mare Orientale, and to the 1908 Tunguska explosion in the U.S.S.R.CREDENTIALS: Dr. Norman Bergrun is an alumnus of Ames Research Laboratory, NACA (National Advisory Committee for Aeronautics) predecessor of Ames Research Center, NASA where he worked twelve years as a research scientist.
