For roughly 2 billion years of Earth's early history, the atmosphere contained no oxygen, the essential ingredient required ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history. Our history. Research shows there are little-known ...

A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

Deaths of nearby massive stars may have played a significant role in triggering at least two mass extinction events in Earth's history, according to new research. The explosive supernova deaths of ...

Conventionally, the moon is thought to have formed during one big impact, but a three-impact model might make more sense ...

A rocky outcrop in a remote corner of northern Quebec appears serene in its eerie isolation on the eastern shore of Canada’s Hudson Bay. But over the past two decades, this exposed remnant of ancient ...

A new study traces a 120-million-year-old 'super-eruption' to its source, offering new insights into Earth's complex geological history. Geologists led by the University of Maryland and the University ...

Pollen grains are far more than allergens — they are also nature’s time capsules, preserving clues about Earth’s past environments for millions of years. Pollen’s tough outer shell enables it to ...
