New model can predict carbon cycle presence on exoplanets

Life thrives at stable temperatures. On Earth, this is facilitated by the carbon cycle. Scientists at SRON, VU and RUG have now developed a model that predicts whether there is a carbon cycle present on exoplanets, provided ...

The first angstrom-scale view of weathering

Sedimentary rocks and water are both abundant on Earth's surface, and over long stretches of time, their interactions turn mountains into sediment. Researchers have long known that water weathers sedimentary rocks both physically, ...

Rocks show Mars once felt like Iceland

Once upon a time, seasons in Gale Crater probably felt something like those in Iceland. But nobody was there to bundle up more than 3 billion years ago.

Geoscientists use zircon to trace origin of Earth's continents

Geoscientists have long known that some parts of the continents formed in the Earth's deep past, but the speed in which land rose above global seas—and the exact shapes that land masses formed—have so far eluded experts.

Venus' ancient layered, folded rocks point to volcanic origin

An international team of researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic ...
