The banded iron formation, located in western China, has been conclusively dated as Cambrian in age. Approximately 527 million years old, this formation is young by comparison to the majority of discoveries to date.

Last autumn, the world was excited by the discovery of an exoplanet called Ross 128 b, which is just 11 light-years away from Earth.

Earth's oxygen levels rose and fell more than once hundreds of millions of years before the planetwide success of the Great Oxidation Event about 2.4 billion years ago, new research from the University of Washington shows.

Carbon-enriched rocky exoplanets have been proposed around dwarf stars as well as around binary stars, white dwarfs and pulsars. However, the mineralogical make up of such planets is poorly constrained.

inds of many evolutionary biologists, the continents were irrelevant early in the Earth's history, because they are assumed to have been barren of life until the first plants appeared, around 0.4 billion years ago.

A new instrument to search for potentially habitable/inhabited planets has started operation at the Subaru Telescope. This instrument, IRD (InfraRed Doppler), will look for habitable planets around red dwarf stars.

The current process for planetary protection policy development is inadequate to respond to increasingly complex solar system exploration missions, says a new report.
