Specks of dust, pushed into dense clumps, collided, stuck together, and grew. While the gas disappeared, the growing bodies clashed in a final violent phase, leaving a series of planets, and much debris. The planets jostled and moved around as they sought a stable arrangement, knocking many small fragments out of the system altogether while others formed a distant icy fringe. The massive violent collisions of this time gouged out vast craters from the newborn planets, and sometimes created moons. Such was the birth of our Solar System. Only recently have scientists begun to find subtle clues of these ancient, violent times. Remarkably, they are still there, if we look carefully at the Earth's oldest rocks, at Mars and the Moon with their ancient surfaces, and at the asteroids, which are themselves startlingly varied small worlds. Clues are also to be found in the meteorites that have landed on Earth. From such splinters, from the precious collection of lunar rocks brought back by the Apollo astronauts, and the information gleaned by spacecraft and the Mars rovers, we are slowly building up a picture of the early days of the planets. Simone Marchi, a planetary scientist involved with several space missions including Dawn, captures the excitement of these discoveries. We learn of the evidence for an early dramatic rearrangement of the big planets; for a once warm and wet Mars where life perhaps still lurks today; and for the huge collisions that have shaped our own planet and affected life's trajectory upon it. For all their destructive power, cosmic collisions have played a critical role in creation. Without them, we would not exist. [b] Simone Marchi presents the emerging story of how cosmic collisions shaped both the solar system and our own planet, from the creation of the Moon to influencing the evolution of life on Earth. [/b] The Earth emerged out of the upheaval and chaos of massive collisions in the infancy of the Solar System, more than four billion years ago. The largest of these events sent into orbit a spray of molten rocks out of which the Moon coalesced. As in ancient mythological tales, this giant catastrophe marks the birth of our planet as we know it. Space exploration has shown that signs of ancient collisions are widespread in the Solar System, from the barren and once-habitable Mars to the rugged asteroids. On Earth these signs are more subtle, but still cataclysmic, such as the massive asteroid strike which likely sparked the demise of the dinosaurs and many other forms of life some 66 million years ago. Signatures of even more dramatic catastrophes are concealed in ancient rocks. These events wreaked havoc on our planet's surface, influencing global climate and topography, while also enriching the Earth with gold and other rare elements. And recently, modern science is finding that they could even have contributed to developing the conditions conducive to life. In Colliding Worlds, Simone Marchi explores the key role that collisions in space have played in the formation and evolution of our solar system, the development of planets, and possibly even the origin of life on Earth. Analysing our latest understanding of the surfaces of Mars and Venus, gleaned from recent space missions, Marchi presents the dramatic story of cosmic collisions and their legacies.
