Plate tectonics is a fundamental factor in the sustained habitability of Earth, but its time of onset is unknown, with ages ranging from the Hadean to...
Precursors of the molecules needed for the origin of life may have been generated by chemical reactions promoted by meteoritic and volcanic particles approximately...
Life most likely started during the Hadean Eon (4.5 to 4 billion years ago). However, the environmental conditions which contributed to the complexity...
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...
Once the Earth was fully formed about 4.5 billion years ago, its subsequent evolution was governed by complex geophysical processes. The planet, however,...
A lunar rock sample collected by Apollo 14 astronauts in 1971 contains traces of minerals with a chemical composition common to Earth and very unusual...
New research from the Universities of Bristol and Bath suggests life originated on our planet a lot earlier than previously thought.
An artistic conception...
About 4 billion years ago (Hadean eon), our planet was entirely different than it is now. It was barren, smooth and almost entirely under water with a...
An analysis of rock samples collected from the Superior Province, the region in Canada just north of the Great Lakes, suggests the samples contain components...
A small fragment of a mineral called zircon extracted from a remote rock outcrop in Australia confirms that the Earth’s crust first formed at least 4.4...
