"In graphic novel format, explores asteroids and comets, including their formation, differences, and impact on life on Earth"--

On a dark night as you watch the sky with your friends, a rock with a fiery tail shoots across the sky. A comet! Asteroids and comets hurtle through space, sometimes a little too close to Earth. But did you know that they are linked to life on this planet? From the asteroid Ceres to HalleyÕs comet, blast into space and enter the lonely existence of asteroids and comets.

With a fiery red explosion, a volcano becomes a disaster in the blink of an eye. Lava and ash shower down, covering the landscape for miles. Starting with molten rock beneath EarthÕs surface, each eruption can cause incredible damage and destruction. From volcano formation to studying volcanoes, prepare to jump into a scalding look at volcanic eruptions.

What determines whether complex life will arise on a planet, or even any life at all? Questions such as these are investigated in this groundbreaking book. In doing so, the authors synthesize information from astronomy, biology, and paleontology, and apply it to what we know about the rise of life on Earth and to what could possibly happen elsewhere in the universe. Everyone who has been thrilled by the recent discoveries of extrasolar planets and the indications of life on Mars and the Jovian moon Europa will be fascinated by Rare Earth, and its implications for those who look to the heavens for companionship.

This interdisciplinary book probes the subject of extraterrestrial intelligent life, offering scientific and technological implications, discussing the philosophical and religious connotations and rebuffing pseudo-scientific assertions such as ‘rare earth’. The author discusses such philosophical questions as: What is intelligence? What is consciousness? Should we expect ETIs to be conscious beings? Also discussed is the viability of future astronautics which would enable closer human contact with ETI.

Does ETI existence spell the death of Christianity? The increasingly popular answer is "yes". Marie George argues, to the contrary, that Christian belief is compatible with ETI existence, by examining Roman Catholic teaching and Scripture. She then makes a case that while Christian belief does not exclude ETI existence, it does render it improbable. George goes on to expose the faulty reasoning behind the common opinion that science indicates that the universe surely contains other intelligent life forms. She closes with speculations on what the Catholic Church might eventually say about ETIs. Central to her analysis is the cosmic role of Christ. "I appreciate arguments like those in Christianity and Extraterrestrials?, laid out carefully and investigated thoroughly. If more writers proceeded with Dr. George's care and courtesy, there would be new hope for peace in the world." John L. Barger, Ph.D. Publisher, Sophia Institute Press "Although some of Dr. George's claims are controversial, she is clearly an author seeking the truth and open to opposing arguments. Moreover, she has sought out the best sources and used them wisely-in short, an admirable scholarly presentation." Michael J. Crowe Cavanaugh Professor Emeritus, University of Notre Dame and author of The Extraterrestrial Life Debate, 1750?1900

Sir Isaac Newton famously said, regarding his discoveries, "If I have seen further it is by standing upon the shoulders of giants." The Evolving Universe and the Origin of Life describes, complete with fascinating biographical details of the thinkers involved, the ascent to the metaphorical shoulders accomplished by the greatest minds in history. For the first time, a single book can take the reader on a journey through the history of the universe as interpreted by the expanding body of knowledge of humankind. From subatomic particles to the protein chains that form life, and expanding in scale to the entire universe, this book covers the science that explains how we came to be. The Evolving Universe and the Origin of Life contains a great breadth of knowledge, from astronomy to physics, from chemistry to biology. It includes over 350 figures that enhance the comprehension of concepts both basic and advanced, and is a non-technical, easy-to-read text at an introductory college level that is ideal for anyone interested in science as well as its history.

The remarkable story of how our solar system came to be The birth and evolution of our solar system is a tantalizing mystery that may one day provide answers to the question of human origins. From Dust to Life tells the remarkable story of how the celestial objects that make up the solar system arose from common beginnings billions of years ago, and how scientists and philosophers have sought to unravel this mystery down through the centuries, piecing together the clues that enabled them to deduce the solar system's layout, its age, and the most likely way it formed. Drawing on the history of astronomy and the latest findings in astrophysics and the planetary sciences, John Chambers and Jacqueline Mitton offer the most up-to-date and authoritative treatment of the subject available. They examine how the evolving universe set the stage for the appearance of our Sun, and how the nebulous cloud of gas and dust that accompanied the young Sun eventually became the planets, comets, moons, and asteroids that exist today. They explore how each of the planets acquired its unique characteristics, why some are rocky and others gaseous, and why one planet in particular—our Earth—provided an almost perfect haven for the emergence of life. From Dust to Life is a must-read for anyone who desires to know more about how the solar system came to be. This enticing book takes readers to the very frontiers of modern research, engaging with the latest controversies and debates. It reveals how ongoing discoveries of far-distant extrasolar planets and planetary systems are transforming our understanding of our own solar system's astonishing history and its possible fate.
