Editor’s note: As we begin to study worlds in our own solar system that might have life we use our home world as a testbed for the various ways to […]
By McKenzie Harris: In the shadow of South Australia’s largest mountain range beneath the outback soil lies a fossil record that reveals a rich history of life on Earth. Fossils […]
The Pilbara in northwestern Australia exposes some of the oldest rocks on Earth, over 3.6 billion years old. The iron-rich rocks formed before the presence of atmospheric oxygen, and life […]
Paleoarchean jaspilites are used to track ancient ocean chemistry and photoautotrophy because they contain hematite interpreted to have formed following biological oxidation of vent-derived Fe(II) and seawater P-scavenging.
As life on Earth rapidly expanded a little over 500 million years ago during the “Cambrian explosion,” Earth had tectonic plates slowly crashing into each other, building mountains and starting […]
This stromatolite formed about 2.7 billion years ago and was collected from an ancient lake environment preserved in the Tumbiana Formation, a succession of clastic and carbonate rocks outcropping along […]
To learn about the first organisms on our planet, researchers have to analyse the rocks of the early Earth. These can only be found in a few places on the […]
Microfossils from Western Australia may capture a jump in the complexity of life that coincided with the rise of oxygen in Earth’s atmosphere and oceans, according to an international team […]
In June 2023, NASA’s Mars Exploration Program leaders joined their counterparts from the Australian Space Agency, ESA (European Space Agency), and the Australian Commonwealth Scientific and Industrial Research Organization (CSIRO) […]
