Long before oceans stabilized and continents formed, Hadean Earth was a world of molten rock, relentless asteroid impacts, and toxic atmospheres. Surface temperatures were extreme, and the young ...

Our Earth is about 4.5 billion years old and, through careful work, scientists have pieced together a timeline of its past. But much of its earliest history remains a mystery. Scant geological ...

Both the moon and Earth were pummeled by an unrelenting cosmic barrage, and this bombardment had profound effects on the development of our planet. Researchers from Curtin University in Australia ...

Earth formed 4.54 billion years ago. The first period of the history of the Earth was known as the Hadean Period which lasted from 4.54 billion to 4 billion years ago. During that time, Earth was ...

A new study says repeated asteroid impacts drove heat deep into the young Earth and kept its crust weak. This suggests heavy bombardment may have helped form continents while erasing most Hadean rocks ...

In May 2018, the island of Mayotte, between Madagascar and Mozambique, began to experience a series of earthquakes that led ...

Earth is the only planet we know of with buoyant, silica-rich continents. But, despite decades of research, geologists still don’t agree on how they formed. “The continents started appearing around ...

New ANU research is set to radically overturn the conventional wisdom that early Earth was a hellish planet barren of continents. An international research team led by Professor Mark Harrison of the ...

In Earth’s early days, more than 4 billion years ago, the surface was a dangerous and unpredictable place. Violent volcanoes, crashing meteorites, and constant tectonic activity repeatedly resurfaced ...
