EDITORIAL INFORMATION

Cometas, Meteoros y Asteroides wants to discover and show such things as: what are comets and meteors? Where do they come from? How have they influenced the climate and the evolution of life? The answers to many of these fascinating questions are the reason for this book. Here there is the fantastic possibility to consider the disappearance of the dinosaurs as the result of a cosmic event that could well have been the impact of a comet. The cosmic theory of the geographical changes of the axis of the Earth is researched, and many scientists believe that the North Pole is located near Hawaii, and the South Pole somewhere in Africa.

OUR REVIEW

Gibilisco is a mathematician very interested in astronomy and cosmology. In this occasion he enters an exciting field, the one dominated by the small bodies that inhabit the Solar System, those that can somehow affect the Earth. The author not only describes in a simple, clear way the characteristics of these famous objects, but also suggests us the analysis of the latest theories that talk about their influence in the past history of our planet.

Armored with a very divulgative kind of language, Gibilisco will teach us to look for and find comets, describe their orbits, shape and behaviors, and even will deal with some as well known as the Halley. Then he will show us the signals that they can have left on the Earth and their more than probable influence on it. Controversial themes such as the relationship between the comets and the origin of life, the ecological catastrophes produced by these or the future danger that they can represent for us, are treated with objectivity and simplicity. The book, originally published, as so many others, after the arrival in 1986 of the Halley comet, is useful to have a good review of these fascinating bodies and to emphasize the importance of their presence in our cosmic neighbourhood.
