Comets are small bodies, but of great cosmic relevance. Given its pristine nature, they may preserve valuable and unique information on thechemical and physical processes that took place in theearly solar system, and that may be occurring in the formation of other planetary systems. They might have even played a very important role in the origin of life on Earth. Beyond that, since ancient times comets have inspired awe, superstition, and also curiosity anddebate. Their sudden apparitions challenged the long-held view of the immutability of the heavens, which triggered a long debate on whether comets had a heavenly or terrestrial nature. Therefore, comets have a prominent role in the history of scienti?cthought, that goes back to the most ancient civilizations. The last apparition of comet Halley in 1986 was a landmark since it arouse a great expectation in the scienti?c community and in the public at large. For the ?rst time, a ?otilla of spacecrafts visited a comet. Agreat number of popular and technical books were written on Halley, and comets in general, around the mid-eighties. The interest in comets never subsided after Halley’s passage which is re?ected in the large volume of printed material on these bodies. I have taken the challenge to write a new book on comets that summarizes most of the recent advances on thesubject, including my own workdeveloped during the last 25 years.

In the gripping start to this young adult science fiction adventure series by popular Colorado radio host Dom Testa, the teenage crew of the starship Galahad must find a new home for humanity among the stars--if they fail, it will be the end of the human race.... When the tail of the comet Bhaktul flicks through the Earth's atmosphere, deadly particles are left in its wake. Suddenly, mankind is confronted with a virus that devastates the adult population. Only those under the age of eighteen seem to be immune. Desperate to save humanity, a renowned scientist proposes a bold plan: to create a ship that will carry a crew of 251 teenagers to a home in a distant solar system. Two years later, the Galahad and its crew—none over the age of sixteen—is launched. Two years of training have prepared the crew for the challenges of space travel. But soon after departing Earth, they discover that a saboteur is hiding on the Galahad! Faced with escalating acts of vandalism and terrorized by threatening messages, sixteen-year-old Triana Martell and her council soon realize that the stowaway will do anything to ensure that the Galahad never reaches its destination. The teens must find a way to neutralize their enemy. For if their mission fails, it will mean the end of the human race....

"I tremble when I recall the terrible appearance [the comet] had on Saturday evening in the clear sky, when it was observed by everybody with inexpressible astonishment. It seemed as though the heavens were burning, or as if the very air was on fire...[F]rom this little star stretched out such a wonderfully long tail that even an intellectual man was overcome with trembling; one's hair stood on end as this uncommon, terrible, and indescribable tail came into view...O wonderful almighty God! The heavens show thy might and the earth thy handiwork!" — Eyewitness account of a comet which appeared over Europe on December 24, 1680 The appearance of this comet caused so many panicked inquiries to be made of Pierre Bayle, one of the Enlightenment's greatest thinkers, that he decided to formally respond to them, hence the present work, which first appeared in 1682. The book's principle task was to undermine the influence of "superstition" in political life, and it was here that Bayle made the notorious suggestion, unique in the history of political thought until then, that a decent society of atheists is possible in principle. There is no other English translation of this book in print—the only other version was printed in 1708. This translation is based on a recently revised critical edition of the complete French text and includes a substantial interpretive essay that both elucidates the arguments of the work and indicates the importance of Bayle in the history of the modern Enlightenment.

Divided into two parts, the first four chapters of Comets and their Origin refer to comets and their formation in general, describing cometary missions, comet remote observations, astrochemistry, artificial comets, and the chirality phenomenon. The second part covers the cometary ROSETTA mission, its launch, journey, scientific objectives, and instrumentations, as well as the landing scenario on a cometary nucleus. Along the way, the author presents general questions concerning the origin of terrestrial water and the molecular beginnings of life on Earth, as well as how the instruments used on a space mission like ROSETTA can help answer them. The text concludes with a chapter on what scientists expect from the ROSETTA mission and how its data will influence our life on Earth. As a result, the author elucidates highly topical and fascinating knowledge to scientists and students of various scientific backgrounds, allowing them to work with ROSETTA's data.
