A team of geologists from Curtin University has discovered unequivocal evidence for a hypervelocity meteorite impact 3.47 billion years ago (Archean Eon)...
In the new study, Dr. David Hernández Uribe from the University of Illinois Chicago used computer models to study the formation of magmas thought to hold...
About 2.5 billion years ago, free oxygen first started to accumulate to meaningful levels in Earth’s atmosphere, setting the stage for the rise of complex...
Stromatolites are solid, laminar structures reflecting complex interplays between microbial communities and their environment.

New research led by Curtin University geologists suggests that regions of space with dense interstellar clouds may send more high-energy comets crashing...
The nature of Earth’s earliest crust and crustal processes remains enigmatic due to the almost complete lack of a rock record older than 4 billion years...
A team of researchers from the United States and Austria has analyzed remnants of ancient asteroids and modeled the effects of their violent collisions...
Using a new gene-analyzing technique, researchers from MIT and elsewhere have found that all extant species of cyanobacteria can be traced back to a common...
Paleontologists have discovered the exceptionally well-preserved, 3.42-billion-year-old filamentous microfossils in a paleo-subseafloor hydrothermal vein...
Once the Earth was fully formed about 4.5 billion years ago, its subsequent evolution was governed by complex geophysical processes. The planet, however,...
Reconstructing the emergence and weathering of Earth’s continental crust in the Archean eon is crucial for our understanding of early ocean chemistry,...
A team of geobiologists from Germany has found biologically-relevant primordial organic molecules and gases in fluid inclusions trapped in 3.5-billion-year-old...
An analysis of rocks from the Honeyeater Basalt of the East Pilbara Craton, a stable block of crust in Western Australia, provides strong evidence that...
The surface of Earth was likely covered by a global ocean 3.24 billion years ago (Archean Eon), according to a new study published in the journal Nature...
A team of researchers from the University of Washington and NASA’s Ames Research Center has analyzed iron-rich micrometeorites collected from 2.7 billion-year-old...
When and how the Earth evolved from a molten mass into a rocky planetary body continually resurfaced by plate tectonics remain some of the biggest questions...
Researchers have found exceptionally preserved organic matter inside samples of rock from the 3.5-billion-year-old Dresser Formation in the Pilbara region...
Earth’s magnetic field protects and makes our planet habitable by stopping harmful high-energy particles from space, including from the Sun. The source...
A new theory on the thermal evolution of Earth explains why the planet’s upper mantle was cool enough to produce diamonds in the Archean Eon between...
Dr. Tanai Cardona, a researcher with Imperial College London, UK, studied molecular machines responsible for oxygenic photosynthesis and found the process...
