It's a fairly true-color representation of what Earth would look like from space. These deposits, and the carbon-12 ratios they show in the inclusions, date life on Earth to more than 4 billion years ago. In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust. These images, honored in Nikon’s annual Small World photo competition, are reminders of the colorful wonders invisible to the naked eye. Together, these elements make up roughly 75 percent of the rocks on Earth today, he explains. Maybe earth was already covered in water (scientists not completely sure). Our 4.54-billion-year-old planet probably experienced its hottest temperatures in its earliest days, when it was still colliding with other rocky debris .

The senior paleontologist at London's Natural History Museum presents an account of life on Earth from the Big Bang to the advent of humankind, based entirely on the evidence of fossils, stones, and other natural artifacts Chalcedonies include many types of cryptocrystalline quartz gems and feature a number of different colors. It is the most ancient fragment of Earth’s crust yet found and contains zircons that date back nearly 4.4 billion years. The solar system, the sun and the earth formed about 4.5 Gyrs ago. By 2.3 billion years ago a bacterium emerged that could convert sunlight into usable energy. The bodies in the Solar System formed and evolved with the Sun. Our Solar system is believed to have precisely that age, it was just forming then so it could not yet be called a proper Solar system. Nasa's Goddard Space Flight Center has taken a stab at visualising the Martian world of 3.7 billion years ago ahead of its Mars Atmosphere and . A lot of the water that is now locked up in glaciers was in the ocean, which means the . Earth was born at midnight on this 24-hour clock, 4.5 billion years ago, but its violent history began well before that, when huge ancient stars that had reached the ends of their lives exploded. For the test, they collected zircons just older than 4 billion years—each about 100 microns across or roughly the width of a human hair—from the Jack Hills region of Western Australia. And both have a useful feature: they have more than one type, or isotope. These and other seemingly fantastic scenarios are the very possible realities explored in Peter Ward's Future Evolution, a penetrating look at what might come next in the history of the planet. E A Bell et al, Proc. More than half of the ancient zircons tested reveal early interactions between water and rock, in a range of different environments. Land masses could then exist and, when it was cold enough to rain, the oceans formed. 4 billion years ago, the atmosphere of Mars could have been rich in oxygen and thick enough and warm enough to support oceans of liquid water - a critical ingredient for life. The age of the rock was estimated to be 3.8 billion years, 700 million years from the Earth's creation. This was before humans carved its wonders on stone, before trees etched the seasons in their rings, before plate tectonics buckled Earth’s surface to expose the ancient layers in growing mountain belts. Other zircons bear the signatures of dissolved minerals that crystallize to form rocks like chert or banded iron formations in lakes or oceans. According to the developers, it can be useful for studying the past of the Earth. The oldest material found in the Solar System is dated to 4.5682 +0.0002 −0.0004 Ga (billion years) ago.

Using the chemical fingerprints of zircons, the team identified an array of sediments likely present on early Earth, where the oldest biochemical reactions could have brewed. Once upon a time, about 4.5 billion years ago, the Earth was an unformed doughnut of molten rock called a synestia — and the moon was hidden in the filling. It's key events … In The Deep History of Ourselves, LeDoux argues that the key to understanding human behavior lies in viewing evolution through the prism of the first living organisms.
