Since the 1970s, planetary geologists have known that volcanic features cover large swaths of Mars. Early Mariner 9 images ...

Sediments from Scotland hint that ocean-atmosphere interactions continued more than 600 million years ago despite widespread ice.

When the supercontinent Pangea began to fragment around 200 million years ago during the Early Jurassic, it reshaped the face of the planet. Vast new oceans opened, continents drifted apart and the ...

A new international study published in Earth and Planetary Science Letters reveals that the boundaries between geological epochs and periods, even though randomly distributed, follow a hidden, ...

Sometimes to truly study something up close, you have to take a step back. That's what Andrea Donnellan does. An expert in Earth sciences and seismology, she gets much of her data from a bird's-eye ...

Scientists at MIT have found compelling chemical evidence that Earth’s earliest animals were likely ancient sea sponges.

Tardigrades, commonly known as water bears, may be better suited by a new name: Tardiguardians of the Galaxy. Unlike the fictional ragtag team of unenthusiastic heroes, the microscopic animals are ...

Scientists are trying to understand why the amount of CO2 in the atmosphere changed by about 90 parts per million (ppmv) between icy (glacial) and warmer (interglacial) periods in Earth’s history.

At the Cascadia subduction zone in the Pacific Northwest, one tectonic plate is moving underneath another. New experimental work at UC Davis shows how rocks on faults deep in the Earth can cement ...

Researchers discovered a new field of ancient tektites in South Australia, revealing a long-forgotten asteroid impact. These 11-million-year-old glass fragments differ chemically and geographically ...
