西蒙娜·马奇（Simone Marchi）讲述了宇宙碰撞如何塑造太阳系和我们自己的星球的新故事，从月球的诞生到影响地球上生命的进化。
40多亿年前，在太阳系诞生初期，地球经历了大规模碰撞的动荡和混乱。这些事件中最大的一次将熔化的岩石喷入轨道，月球从中聚结。正如在古代神话故事中一样，这场巨大的灾难标志着我们所知道的地球的诞生。
太空探索表明，从贫瘠、曾经宜居的火星到崎岖不平的小行星，古代碰撞的迹象在太阳系中广泛存在。在地球上，这些迹象更加微妙，但仍然是灾难性的，例如大约6600万年前，小行星的大规模撞击可能导致恐龙和许多其他生命形式的灭绝。更为戏剧性的灾难的特征隐藏在古老的岩石中。这些事件对地球表面造成了严重破坏，影响了全球气候和地形，同时也使地球富含黄金和其他稀有元素。最近，现代科学发现它们甚至有助于创造有利于生命的条件。
在《碰撞世界》一书中，西蒙娜·马尔奇探索了太空碰撞在太阳系的形成和演化、行星的发展，甚至可能是地球生命起源中所起的关键作用。通过分析我们对火星和金星表面的最新了解，马奇从最近的太空任务中收集到了这些信息，他讲述了宇宙碰撞及其遗产的戏剧性故事。
Colliding Worlds: How Cosmic Encounters Shaped Planets and Life (PDF)
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.
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.
