There's a billion-year gap in Earth's geological history. A new study seeks to explain the mystery.

A layer of rock just 520 million years old sat directly on top of ancient rock dating back 1.4 to 1.8 billion years.

Earth scientists often face huge challenges when researching Earth's history: many significant events occurred such a long time ago that there is little direct evidence available. Consequently, ...

Much of our understanding of Earth's past is derived from stratigraphic records exposed in rock outcrops or recovered from drilled cores. These records span immense time intervals, from thousands to ...

Tiny bits of Earth’s atmosphere have been drifting to the moon for billions of years, guided by Earth’s magnetic field. Rather than blocking particles, the magnetic field can funnel them along ...

While the planet has experienced much warmer periods in the past, scientists have found that the current rate of temperature rise is much faster than any warming seen in the last 65 million years.

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 ...
